- it aims to partially fix performance issue reported: https://bugzilla.mozilla.org/show_bug.cgi?id=857031; - the idea is too avoid to use byte arrays but use ImageBitmap which are a way faster to draw: * an ImageBitmap is Transferable which means that it can be built in the worker instead of in the main thread: - this is achieved in using an OffscreenCanvas when it's available, there is a bug to enable them for pdf.js: https://bugzilla.mozilla.org/show_bug.cgi?id=1763330; - or in using createImageBitmap: in Firefox a task is sent to the main thread to build the bitmap so it's slightly slower than using an OffscreenCanvas. * it's transfered from the worker to the main thread by "reference"; * the byte buffers used to create the image data have a very short lifetime and ergo the memory used is globally less than before. - Use the localImageCache for the mask; - Fix the pdf issue4436r.pdf: it was expected to have a binary stream for the image; - Move the singlePixel trick from operator_list to image: this way we can use this trick even if it isn't in a set as defined in operator_list. |
