File
Path of the texture file. The whole file is one texture; the rectangle to draw comes from the concrete class.

Edit documentationA texture provider that draws from a texture file it names, usually a hand-made atlas shared by many icons. The concrete classes differ only in how they cut the texture up: AtlasData uses one rectangle, the sliced forms use a row, a column or a grid of them.
The texture is loaded when the object loads, not when the icon is first drawn. A file that is missing leaves the provider without a texture, and the icon draws nothing.
Every position inside the texture is written in pixels of the source resolution, the size the atlas had when the icon was authored. The client only divides by those two numbers; it never reads the size of the texture it loaded. So a replacement texture at a different resolution keeps working as long as its layout is the same.
Properties
mTextureSourceResolutionHeight
U32 Height, in pixels, of the texture the coordinates were authored against. Vertical coordinates are divided by it to get V. Zero works as for the width.
mTextureSourceResolutionWidth
U32 Width, in pixels, of the texture the coordinates were authored against. Horizontal coordinates are divided by it to get U.
Zero turns the division off, and the coordinates are then used as U values as they are. The class defaults of the sliced forms, which are fractions, rely on that.
