WebGLTextureWrapper
Wrapper for a WebGL texture, containing all the information that was used
to create it.
A WebGLTexture should never be exposed outside the WebGLRenderer,
so the WebGLRenderer can handle context loss and other events
without other systems having to be aware of it.
Always use WebGLTextureWrapper instead.
Constructor
new WebGLTextureWrapper(gl, mipLevel, minFilter, magFilter, wrapT, wrapS, format, pixels, width, height, [pma], [forceSize], [flipY])
Parameters
| name | type | optional | default | description |
|---|---|---|---|---|
| gl | WebGLRenderingContext | No | WebGL context the texture belongs to. | |
| mipLevel | number | No | Mip level of the texture. | |
| minFilter | number | No | Filtering of the texture. | |
| magFilter | number | No | Filtering of the texture. | |
| wrapT | number | No | Wrapping mode of the texture. | |
| wrapS | number | No | Wrapping mode of the texture. | |
| format | number | No | Which format does the texture use. | |
| pixels | object | No | pixel data. | |
| width | number | No | Width of the texture in pixels. | |
| height | number | No | Height of the texture in pixels. | |
| pma | boolean | Yes | true | Does the texture have premultiplied alpha? |
| forceSize | boolean | Yes | false | If true it will use the width and height passed to this method, regardless of the pixels dimension. |
| flipY | boolean | Yes | false | Sets the UNPACK_FLIP_Y_WEBGL flag the WebGL Texture uses during upload. |
