GetBlendModes
<static> GetBlendModes()
Description:
Returns an array which maps the default blend modes to supported Canvas blend modes.
If the browser doesn't support a blend mode, it will default to the normal source-over blend mode.
Returns: array - Which Canvas blend mode corresponds to which default Phaser blend mode.

SetTransform
<static> SetTransform(renderer, ctx, src, camera, [parentMatrix])
Description:
Takes a reference to the Canvas Renderer, a Canvas Rendering Context, a Game Object, a Camera and a parent matrix and then performs the following steps:
- Checks the alpha of the source combined with the Camera alpha. If 0 or less it aborts.
- Takes the Camera and Game Object matrix and multiplies them, combined with the parent matrix if given.
- Sets the blend mode of the context to be that used by the Game Object.
- Sets the alpha value of the context to be that used by the Game Object combined with the Camera.
- Saves the context state.
- Sets the final matrix values into the context via setTransform.
- If the Game Object has a texture frame, imageSmoothingEnabled is set based on frame.source.scaleMode.
- If the Game Object does not have a texture frame, imageSmoothingEnabled is set based on Renderer.antialias.
This function is only meant to be used internally. Most of the Canvas Renderer classes use it.
Parameters:
name | type | optional | description |
|---|---|---|---|
renderer | No | A reference to the current active Canvas renderer. | |
ctx | CanvasRenderingContext2D | No | The canvas context to set the transform on. |
src | No | The Game Object being rendered. Can be any type that extends the base class. | |
camera | No | The Camera that is rendering the Game Object. | |
parentMatrix | Yes | A parent transform matrix to apply to the Game Object before rendering. |
Returns: boolean - true if the Game Object context was set, otherwise false.
