requireBitmapSheetSize
Applies generic image safety and the independent bitmap-sheet input ceiling before allocating a provider sheet. The default sheet ceiling allows the default raster cache to retain a sheet and its largest copied glyph together. Raising this input ceiling may cause repeated decoding under a smaller cache, but never changes provider selection between cache modes.
Parameters
width
decoded sheet width.
height
decoded sheet height.
Throws
when the sheet exceeds an image or bitmap input ceiling.
