Functions

function autoDetectRenderer

autoDetectRenderer: <VIEW extends ICanvas = ICanvas>(
    options?: Partial<IRendererOptionsAuto>
) => IRenderer<VIEW>;

This helper function will automatically detect which renderer you should be using. WebGL is the preferred renderer as it is a lot faster. If WebGL is not supported by the browser then this function will return a canvas renderer. PIXI autoDetectRenderer
Parameter options
Options to use.

function autoDetectResource

autoDetectResource: <R extends Resource, RO>(source: unknown, options?: RO) => R;

Create a resource element from a single source element. This auto-detects which type of resource to create. All resources that are auto-detectable must have a static test method and a constructor with the arguments (source, options?). Currently, the supported resources for auto-detection include: - PIXI.ImageResource - PIXI.CanvasResource - PIXI.VideoResource - PIXI.SVGResource - PIXI.BufferResource PIXI autoDetectResource
Parameter source
Resource source, this can be the URL to the resource, a typed-array (for BufferResource), HTMLVideoElement, SVG data-uri or any other resource that can be auto-detected. If not resource is detected, it's assumed to be an ImageResource.
Parameter options
Pass-through options to use for Resource
Parameter
{number} [options.width] - Width of BufferResource or SVG rasterization
Parameter
{number} [options.height] - Height of BufferResource or SVG rasterization
Parameter

class BaseRenderTexture

class BaseRenderTexture extends BaseTexture {}

A BaseRenderTexture is a special texture that allows any PixiJS display object to be rendered to it.
__Hint__: All DisplayObjects (i.e. Sprites) that render to a BaseRenderTexture should be preloaded otherwise black rectangles will be drawn instead.
A BaseRenderTexture takes a snapshot of any Display Object given to its render method. The position and rotation of the given Display Objects is ignored. For example:
Example 1
import { autoDetectRenderer, BaseRenderTexture, RenderTexture, Sprite } from 'pixi.js';
const renderer = autoDetectRenderer(); const baseRenderTexture = new BaseRenderTexture({ width: 800, height: 600 }); const renderTexture = new RenderTexture(baseRenderTexture); const sprite = Sprite.from('spinObj_01.png');
sprite.position.x = 800 / 2; sprite.position.y = 600 / 2; sprite.anchor.x = 0.5; sprite.anchor.y = 0.5;
renderer.render(sprite, { renderTexture });
// The Sprite in this case will be rendered using its local transform. // To render this sprite at 0,0 you can clear the transform sprite.setTransform();
const baseRenderTexture = new BaseRenderTexture({ width: 100, height: 100 }); const renderTexture = new RenderTexture(baseRenderTexture);
renderer.render(sprite, { renderTexture }); // Renders to center of RenderTexture PIXI

class Filter

class Filter extends Shader {}

A filter is a special shader that applies post-processing effects to an input texture and writes into an output render-target.
of the .
### Usage Filters can be applied to any DisplayObject or Container. PixiJS' FilterSystem renders the container into temporary Framebuffer, then filter renders it to the screen. Multiple filters can be added to the filters array property and stacked on each other.
import { Container, Filter } from 'pixi.js'; const filter = new Filter(myShaderVert, myShaderFrag, { myUniform: 0.5 }); const container = new Container(); container.filters = [filter];
### Previous Version Differences
In PixiJS **v3**, a filter was always applied to _whole screen_.
In PixiJS **v4**, a filter can be applied _only part of the screen_. Developers had to create a set of uniforms to deal with coordinates.
In PixiJS **v5** combines _both approaches_. Developers can use normal coordinates of v3 and then allow filter to use partial Framebuffers, bringing those extra uniforms into account.
Also be aware that we have changed default vertex shader, please consult .
### Frames
The following table summarizes the coordinate spaces used in the filtering pipeline:
Coordinate Space Description Texture Coordinates The texture (or UV) coordinates in the input base-texture's space. These are normalized into the (0,1) range along both axes. World Space A point in the same space as the world bounds of any display-object (i.e. in the scene graph's space). Physical Pixels This is base-texture's space with the origin on the top-left. You can calculate these by multiplying the texture coordinates by the dimensions of the texture.
### Built-in Uniforms
PixiJS viewport uses screen (CSS) coordinates, (0, 0, renderer.screen.width, renderer.screen.height), and projectionMatrix uniform maps it to the gl viewport.
**uSampler**
The most important uniform is the input texture that container was rendered into. _Important note: as with all Framebuffers in PixiJS, both input and output are premultiplied by alpha._
By default, input normalized coordinates are passed to fragment shader with vTextureCoord. Use it to sample the input.
import { Filter } from 'pixi.js'; const fragment = ` varying vec2 vTextureCoord; uniform sampler2D uSampler; void main(void) { gl_FragColor = texture2D(uSampler, vTextureCoord); } `; const myFilter = new Filter(null, fragment);
This filter is just one uniform less than .
**outputFrame**
The outputFrame holds the rectangle where filter is applied in screen (CSS) coordinates. It's the same as renderer.screen for a fullscreen filter. Only a part of outputFrame.zw size of temporary Framebuffer is used, (0, 0, outputFrame.width, outputFrame.height),
Filters uses this quad to normalized (0-1) space, its passed into aVertexPosition attribute. To calculate vertex position in screen space using normalized (0-1) space:
vec4 filterVertexPosition( void ) { vec2 position = aVertexPosition * max(outputFrame.zw, vec2(0.)) + outputFrame.xy; return vec4((projectionMatrix * vec3(position, 1.0)).xy, 0.0, 1.0); }
**inputSize**
Temporary framebuffer is different, it can be either the size of screen, either power-of-two. The inputSize.xy are size of temporary framebuffer that holds input. The inputSize.zw is inverted, it's a shortcut to evade division inside the shader.
Set inputSize.xy = outputFrame.zw for a fullscreen filter.
To calculate input normalized coordinate, you have to map it to filter normalized space. Multiply by outputFrame.zw to get input coordinate. Divide by inputSize.xy to get input normalized coordinate.
vec2 filterTextureCoord( void ) { return aVertexPosition * (outputFrame.zw * inputSize.zw); // same as /inputSize.xy }
**resolution**
The resolution is the ratio of screen (CSS) pixels to real pixels.
**inputPixel**
inputPixel.xy is the size of framebuffer in real pixels, same as inputSize.xy * resolution inputPixel.zw is inverted inputPixel.xy.
It's handy for filters that use neighbour pixels, like .
**inputClamp**
If you try to get info from outside of used part of Framebuffer - you'll get undefined behaviour. For displacements, coordinates has to be clamped.
The inputClamp.xy is left-top pixel center, you may ignore it, because we use left-top part of Framebuffer inputClamp.zw is bottom-right pixel center.
vec4 color = texture2D(uSampler, clamp(modifiedTextureCoord, inputClamp.xy, inputClamp.zw));
Or:
vec4 color = texture2D(uSampler, min(modifigedTextureCoord, inputClamp.zw));
### Additional Information
Complete documentation on Filter usage is located in the .

class FilterSystem

class FilterSystem implements ISystem {}

System plugin to the renderer to manage filters.
## Pipeline
The FilterSystem executes the filtering pipeline by rendering the display-object into a texture, applying its [filters]PIXI.Filter in series, and the last filter outputs into the final render-target.
The filter-frame is the rectangle in world space being filtered, and those contents are mapped into (0, 0, filterFrame.width, filterFrame.height) into the filter render-texture. The filter-frame is also called the source-frame, as it is used to bind the filter render-textures. The last filter outputs to the filterFrame in the final render-target.
## Usage
PIXI.Container#renderAdvanced is an example of how to use the filter system. It is a 3 step process:
**push**: Use PIXI.FilterSystem#push to push the set of filters to be applied on a filter-target. **render**: Render the contents to be filtered using the renderer. The filter-system will only capture the contents inside the bounds of the filter-target. NOTE: Using PIXI.Renderer#render is illegal during an existing render cycle, and it may reset the filter system. **pop**: Use PIXI.FilterSystem#pop to pop & execute the filters you initially pushed. It will apply them serially and output to the bounds of the filter-target. PIXI

class MaskSystem

class MaskSystem implements ISystem {}

System plugin to the renderer to manage masks.
There are three built-in types of masking: **Scissor Masking**: Scissor masking discards pixels that are outside of a rectangle called the scissor box. It is the most performant as the scissor test is inexpensive. However, it can only be used when the mask is rectangular. **Stencil Masking**: Stencil masking discards pixels that don't overlap with the pixels rendered into the stencil buffer. It is the next fastest option as it does not require rendering into a separate framebuffer. However, it does cause the mask to be rendered **twice** for each masking operation; hence, minimize the rendering cost of your masks. **Sprite Mask Filtering**: Sprite mask filtering discards pixels based on the red channel of the sprite-mask's texture. (Generally, the masking texture is grayscale). Using advanced techniques, you might be able to embed this type of masking in a custom shader - and hence, bypassing the masking system fully for performance wins.
The best type of masking is auto-detected when you push one. To use scissor masking, you must pass in a Graphics object with just a rectangle drawn.
## Mask Stacks
In the scene graph, masks can be applied recursively, i.e. a mask can be applied during a masking operation. The mask stack stores the currently applied masks in order. Each PIXI.BaseRenderTexture holds its own mask stack, i.e. when you switch render-textures, the old masks only applied when you switch back to rendering to the old render-target. PIXI

class ProjectionSystem

class ProjectionSystem implements ISystem {}

System plugin to the renderer to manage the projection matrix.
The projectionMatrix is a global uniform provided to all shaders. It is used to transform points in world space to normalized device coordinates. PIXI

constructor

constructor(renderer: Renderer);

Parameter renderer
The renderer this System works for.

property defaultFrame

defaultFrame: Rectangle;

Default destination frame
This is not used internally. It is not advised to use this feature specifically unless you know what you're doing. The update method will default to this frame if you do not pass the destination frame.
Modifiers
- @readonly

property destinationFrame

destinationFrame: Rectangle;

The destination frame used to calculate the current projection matrix.
The destination frame is the rectangle in the render-target into which contents are rendered. If rendering to the screen, the origin is on the top-left. If rendering to a framebuffer, the origin is on the bottom-left. This "flipping" phenomenon is because of WebGL convention for (shader) texture coordinates, where the bottom-left corner is (0,0). It allows display-objects to map their (0,0) position in local-space (top-left) to (0,0) in texture space (bottom-left). In other words, a sprite's top-left corner actually renders the texture's bottom-left corner. You will also notice this when using a tool like SpectorJS to view your textures at runtime.
The destination frame's dimensions (width,height) should be equal to the source frame. This is because, otherwise, the contents will be scaled to fill the destination frame. Similarly, the destination frame's (x,y) coordinates are (0,0) unless you know what you're doing.
Modifiers
- @readonly

property extension

static extension: ExtensionMetadata;

property projectionMatrix

projectionMatrix: Matrix;

Projection matrix
This matrix can be used to transform points from world space to normalized device coordinates, and is calculated from the sourceFrame → destinationFrame mapping provided.
The renderer's globalUniforms keeps a reference to this, and so it is available for all shaders to use as a uniform.
Modifiers
- @readonly

property sourceFrame

sourceFrame: Rectangle;

The source frame used to calculate the current projection matrix.
The source frame is the rectangle in world space containing the contents to be rendered.
Modifiers
- @readonly

property transform

transform: Matrix;

A transform to be appended to the projection matrix.
This can be used to transform points in world-space one last time before they are outputted by the shader. You can use to rotate the whole scene, for example. Remember to clear it once you've rendered everything. {PIXI.Matrix}

method calculateProjection

calculateProjection: (
    _destinationFrame: Rectangle,
    sourceFrame: Rectangle,
    _resolution: number,
    root: boolean
) => void;

Calculates the projectionMatrix to map points inside sourceFrame to inside destinationFrame.
Parameter _destinationFrame
The destination frame in the render-target.
Parameter sourceFrame
The source frame in world space.
Parameter _resolution
The render-target's resolution, i.e. ratio of CSS to physical pixels.
Parameter root
Whether rendering into the screen. Otherwise, if rendering to a framebuffer, the projection is y-flipped.

method destroy

destroy: () => void;

method setTransform

setTransform: (_matrix: Matrix) => void;

Sets the transform of the active render target to the given matrix.
Parameter _matrix
The transformation matrix

method update

update: (
    destinationFrame: Rectangle,
    sourceFrame: Rectangle,
    resolution: number,
    root: boolean
) => void;

Updates the projection-matrix based on the sourceFrame → destinationFrame mapping provided.
NOTE: It is expected you call renderer.framebuffer.setViewport(destinationFrame) after this. This is because the framebuffer viewport converts shader vertex output in normalized device coordinates to window coordinates.
NOTE-2: PIXI.RenderTextureSystem#bind updates the projection-matrix when you bind a render-texture. It is expected that you dirty the current bindings when calling this manually.
Parameter destinationFrame
The rectangle in the render-target to render the contents into. If rendering to the canvas, the origin is on the top-left; if rendering to a render-texture, the origin is on the bottom-left.
Parameter sourceFrame
The rectangle in world space that contains the contents being rendered.
Parameter resolution
The resolution of the render-target, which is the ratio of world-space (or CSS) pixels to physical pixels.
Parameter root
Whether the render-target is the screen. This is required because rendering to textures is y-flipped (i.e. upside down relative to the screen).

class Renderer

class Renderer extends SystemManager<Renderer> implements IRenderer {}

The Renderer draws the scene and all its content onto a WebGL enabled canvas.
This renderer should be used for browsers that support WebGL.
This renderer works by automatically managing WebGLBatches, so no need for Sprite Batches or Sprite Clouds. Don't forget to add the view to your DOM or you will not see anything!
Renderer is composed of systems that manage specific tasks. The following systems are added by default whenever you create a renderer:
| System | Description | | ------------------------------------ | ----------------------------------------------------------------------------- |
| Generic Systems | Systems that manage functionality that all renderer types share | | ------------------------------------ | ----------------------------------------------------------------------------- | | PIXI.ViewSystem | This manages the main view of the renderer usually a Canvas | | PIXI.PluginSystem | This manages plugins for the renderer | | PIXI.BackgroundSystem | This manages the main views background color and alpha | | PIXI.StartupSystem | Boots up a renderer and initiatives all the systems | | PIXI.EventSystem | This manages UI events. |
| WebGL Core Systems | Provide an optimised, easy to use API to work with WebGL | | ------------------------------------ | ----------------------------------------------------------------------------- | | PIXI.ContextSystem | This manages the WebGL context and extensions. | | PIXI.FramebufferSystem | This manages framebuffers, which are used for offscreen rendering. | | PIXI.GeometrySystem | This manages geometries & buffers, which are used to draw object meshes. | | PIXI.ShaderSystem | This manages shaders, programs that run on the GPU to calculate 'em pixels. | | PIXI.StateSystem | This manages the WebGL state variables like blend mode, depth testing, etc. | | PIXI.TextureSystem | This manages textures and their resources on the GPU. | | PIXI.TextureGCSystem | This will automatically remove textures from the GPU if they are not used. | | PIXI.MultisampleSystem | This manages the multisample const on the WEbGL Renderer |
| PixiJS High-Level Systems | Set of specific systems designed to work with PixiJS objects | | ------------------------------------ | ----------------------------------------------------------------------------- | | PIXI.GenerateTextureSystem | This adds the ability to generate textures from any PIXI.DisplayObject | | PIXI.ProjectionSystem | This manages the projectionMatrix, used by shaders to get NDC coordinates. | | PIXI.RenderTextureSystem | This manages render-textures, which are an abstraction over framebuffers. | | PIXI.MaskSystem | This manages masking operations. | | PIXI.ScissorSystem | This handles scissor masking, and is used internally by PIXI.MaskSystem | | PIXI.StencilSystem | This handles stencil masking, and is used internally by PIXI.MaskSystem | | PIXI.FilterSystem | This manages the filtering pipeline for post-processing effects. | | PIXI.BatchSystem | This manages object renderers that defer rendering until a flush. | | PIXI.Prepare | This manages uploading assets to the GPU. | | PIXI.Extract | This extracts image data from display objects. |
The breadth of the API surface provided by the renderer is contained within these systems. PIXI

class RenderTexture

class RenderTexture extends Texture {}

A RenderTexture is a special texture that allows any PixiJS display object to be rendered to it.
__Hint__: All DisplayObjects (i.e. Sprites) that render to a RenderTexture should be preloaded otherwise black rectangles will be drawn instead.
__Hint-2__: The actual memory allocation will happen on first render. You shouldn't create renderTextures each frame just to delete them after, try to reuse them.
A RenderTexture takes a snapshot of any Display Object given to its render method. For example:
Example 1
import { autoDetectRenderer, RenderTexture, Sprite } from 'pixi.js';
const renderer = autoDetectRenderer(); const renderTexture = RenderTexture.create({ width: 800, height: 600 }); const sprite = Sprite.from('spinObj_01.png');
sprite.position.x = 800 / 2; sprite.position.y = 600 / 2; sprite.anchor.x = 0.5; sprite.anchor.y = 0.5;
renderer.render(sprite, { renderTexture });
// Note that you should not create a new renderer, but reuse the same one as the rest of the application. // The Sprite in this case will be rendered using its local transform. To render this sprite at 0,0 // you can clear the transform
sprite.setTransform();
const renderTexture = new RenderTexture.create({ width: 100, height: 100 });
renderer.render(sprite, { renderTexture }); // Renders to center of RenderTexture PIXI

class Texture

class Texture<R extends Resource = Resource> extends EventEmitter {}

A texture stores the information that represents an image or part of an image.
It cannot be added to the display list directly; instead use it as the texture for a Sprite. If no frame is provided for a texture, then the whole image is used.
You can directly create a texture from an image and then reuse it multiple times like this :
import { Sprite, Texture } from 'pixi.js'; const texture = Texture.from('assets/image.png'); const sprite1 = new Sprite(texture); const sprite2 = new Sprite(texture);
If you didnt pass the texture frame to constructor, it enables noFrame mode: it subscribes on baseTexture events, it automatically resizes at the same time as baseTexture.
Textures made from SVGs, loaded or not, cannot be used before the file finishes processing. You can check for this by checking the sprite's _textureID property.
import { Sprite, Texture } from 'pixi.js'; const texture = Texture.from('assets/image.svg'); const sprite1 = new Sprite(texture); // sprite1._textureID should not be undefined if the texture has finished processing the SVG file
You can use a ticker or rAF to ensure your sprites load the finished textures after processing. See issue [#3085]https://github.com/pixijs/pixijs/issues/3085. PIXI

class UniformGroup

class UniformGroup<LAYOUT = Dict<any>> {}

Uniform group holds uniform map and some ID's for work
UniformGroup has two modes:
1: Normal mode Normal mode will upload the uniforms with individual function calls as required
2: Uniform buffer mode This mode will treat the uniforms as a uniform buffer. You can pass in either a buffer that you manually handle, or or a generic object that PixiJS will automatically map to a buffer for you. For maximum benefits, make Ubo UniformGroups static, and only update them each frame.
Rules of UBOs: - UBOs only work with WebGL2, so make sure you have a fallback! - Only floats are supported (including vec[2,3,4], mat[2,3,4]) - Samplers cannot be used in ubo's (a GPU limitation) - You must ensure that the object you pass in exactly matches in the shader ubo structure. Otherwise, weirdness will ensue! - The name of the ubo object added to the group must match exactly the name of the ubo in the shader.
// UBO in shader: uniform myCoolData { // Declaring a UBO... mat4 uCoolMatrix; float uFloatyMcFloatFace; };
// A new Uniform Buffer Object... const myCoolData = new UniformBufferGroup({ uCoolMatrix: new Matrix(), uFloatyMcFloatFace: 23, }} // Build a shader... const shader = Shader.from(srcVert, srcFrag, { myCoolData // Name matches the UBO name in the shader. Will be processed accordingly. })
