This commit implements a WebP reader and writer for both lossless and lossy WebP, export dialog options for selecting lossless/lossy and quality for lossy, and various internal support for the format. Since writing WebP to e.g. ODT documents would make those images unreadable by previous versions with no WebP support, support for that is explicitly disabled in GraphicFilter, to be enabled somewhen later.

It is a special case when there are additional 12 bytes of color bitfields after the info header. See also the useful comments at https://searchfox.org/mozilla-central/source/image/decoders/nsBMPDecoder.cpp#47 It turned out we generate this type of BMP files internally from EMF files, but in that case the bfOffBits of BITMAPFILEHEADER struct points to the pixel data. In case of Visio, bfOffBits points to the color mask. There was no better solution than preventing jumping back in the stream.

2021-05-05vcl pdfium render: handle widget annotations for form fieldsMiklos Vajna
Note that we render the bitmaps without FPDF_ANNOT, so comments are not rendered into the bitmaps, rather we create them on top of the bitmaps in Draw, explicitly. FPDF_FFLDraw() draws content which is already an annotation, but not yet interactive content; so this just fixes "missing text", as far as the user is concerned. Verified that e.g. vcl/qa/cppunit/data/PangramAcrobatAnnotations.pdf indeed still doesn't render comments into bitmaps after this.

2021-03-03tdf#140606 make PDF parsing more lenient and prevent a crashTomaž Vajngerl
If the external document can't be opened, it tried to continue with the export anyway, which eventually lead to a crash. This is fixed by handling this situation and prevent a crash, however the part of the document in this case isn't exported. The document couldn't be opened because of a parsing error - there was a unexpected null character instead of a whitespace, which made the parser panic. Fix this by making the parser more lenient in such a situation when there is an unexpected null and try to continue parsing. Bug document seems to be created with a buggy PDF writer, but other PDF readers don't complain when parsing the document so it looks to be a valid. qpdf --check doesn't complain either. Added a test that checks a document with a null parses.

2021-02-02tdf#139869 vcl: fix lazy-loading of BMP images with logic sizeMiklos Vajna
Regression from commit 7b355669c6ddeab2e6cec692d6afdff41c61d0fb (Function to load graphic swapped out (loaded on demand), 2018-04-14), the code assumes that the map mode and size of a graphic is the same when the image is not yet loaded and when it's loaded already. This was not the case for the BMP import, where ImplReadDIBBody() produced a map mode with scaling and MapUnit::MapMM as the map unit, while GraphicDescriptor assumed that the logic size is always MapUnit::Map100thMM. This resulted in SwNoTextNode::HasContour() using one map mode when the contour polygon is imported and an other one was used while renderin, effectively hiding the image. Fix the problem by extending GraphicDescriptor, so a format detector can opt in to provide its own map mode and size according to that map mode, this way the detector and the BMP import will create matching map modes and sizes, resulting in a visible image in the bugdoc.

2019-05-10introduce graphic format detector (and basic metadata)Tomaž Vajngerl
Currently we detect a graphic format in a ImpPeekGraphicFormat method, which is called when reading a graphic from a stream. The code is quite convoluted and doesn't help with readability of graphicfilter.cxx Additionally there exists an detection code written for the UNO class GraphicDescriptor, which duplicates the detection, but can in addition also extract other metadata at the same time. This introduces the initial implementation of GraphicFormatDetector class. It will first replace the code in ImpPeekGraphicFormat to detect the graphic format and then later also be extended to do what the GraphicDescriptor is doing. But currently it only duplicates the implementation of ImpPeekGraphicFormat. The problem with both of the current solution is that there are not any tests written. For the GraphicFormatDetector however the approach is to add test cases to check the current implementation and only then refactor the code.
