Add (basic) support for transfer functions to Images (issue 6931, bug 1149713) #12219
Conversation
I completely overlooked the fact that `PartialEvaluator.handleSetFont` also updates the current `state`, which means that currently we're not actually handling font data correctly for cached /ExtGState data. (Thankfully, using /ExtGState to set a font is somewhat rare in practice.)
… 1149713) This is *similar* to the existing transfer function support for SMasks, but extended to simple image data. Please note that the extra amount of data now being sent to the worker-thread, for affected /ExtGState entries, is limited to *at most* 4 `Uint8Array`s each with a length of 256 elements.
