2018-11-14Remove TARGA output support.HEADmasterTor Andersson
It is not very useful.
2018-11-13Bug 697414: Allow more encodings in XML parser.Tor Andersson
Support some common FB2 encodings as well as UTF-8 and UTF-16.
2018-11-13Add fz_strncasecmp.Tor Andersson
2018-11-13Add more encoding tables.Tor Andersson
Add tables for Windows-1250, Windows-1251, and ISO-8859-1. Also add unicode_from_encoding tables. Move encodings from PDF namespace to Fitz.
2018-11-13Use first character's bbox even if it is empty.Tor Andersson
Otherwise we get unsightly [0 0 0 0] bounding boxes for lines with a single zero area character.
2018-11-13Bug 697206: Tweak when to use the PDF font metrics in fz_advance_glyph.Tor Andersson
Only use the PDF font metrics for stretched substitute fonts, in all other cases, trust the embedded font file instead.
2018-11-13Bug 700143: Ignore duplicate text objects in text extraction.Tor Andersson
Rendering modes like fill+stroke or fill+stroke+clip send the same text object multiple times. Only extract the text from the first instance.
2018-11-12Bug 699992: Use feBlend filters in SVG output for PDF blendings.Robin Watts
This doesn't cover all the PDF options, but it's better than nothing. This does mean we have to "enable-background" for all SVG files whether they use blending or not.
2018-11-08Fix 699343: Skip spaces before data in DCTDecode filter.Tor Andersson
2018-11-08Fix 699352: Call begin_layer for all marked content in PDF.Tor Andersson
Since we call end_layer without distinction, we should also call begin_layer the same way. Also change the XML to emit separate tags for beginning and ending a layer, since there is no guarantee the layer calls will be neatly nested with clipping pushes and pops; nor is there a guarantee that the PDF will even balance the BMC/BDC and EMC operators.
2018-11-07Fix typo.Tor Andersson
2018-11-07Fix 698971: Detect ICC colorspace mismatch in TIFF loader.Tor Andersson
Make sure that the ICC colorspace has the same number of components as the photometric interpretation.
2018-11-07Fix 700140: Ask LCMS transform to copy alpha channels.Tor Andersson
2018-11-07Make compression bomb detection optional.Tor Andersson
2018-11-07pnm: Take alpha into account when skipping over image data.Sebastian Rasmussen
2018-11-07Add explicit jmp_buf dereferencing to allow using fz_try from C++.Tor Andersson
2018-11-07Handle bogus font ascender and descender values.Tor Andersson
2018-11-07Fix 700030: Use actual font glyph widths when extracting text.Tor Andersson
Only use the PDF character widths when also stretching glyphs to match the PDF metrics.
2018-11-07Fix 700030: Tweak text extraction space adding heuristics.Tor Andersson
Ignore space-sized backward motions. Assume that these motions are either extreme levels of kerning, or something else fishy going on.
2018-11-07Fix 700043: Don't assume a font is t3 just because fz_outline_glyph fails.Tor Andersson
2018-11-01Bug 700040: tar: Handle posix, ustar and v7 tar formats.Sebastian Rasmussen
These formats are all almost identical to GNU tar format.
2018-10-26Guard all calls to the passthrough device in the test device.Sebastian Rasmussen
Without guards the device calls might end up with a device pointer being NULL, causing segfaults.
2018-10-26Avoid dropping stream/color converter twice upon exception.Sebastian Rasmussen
2018-10-26Rewrite try/always/catch macros to allow fz_context to be opaque.Tor Andersson
Hide fz_stack_slot and exception handling details too. Also make sure we have an initialized jmp_buf so we can safely throw from the always block even in the exception stack overflow case.
2018-10-26Use 14 bits of precision for image drawing, to allow for larger images.Tor Andersson
Now the image size limit is 131072 x 131072 instead of 32768 x 32768.
2018-10-25Make fixed point math precision in image drawing a #define.Tor Andersson
2018-10-25Handle premultiplied alpha in generic pixmap color conversion.Tor Andersson
2018-10-25Handle premultiplied alpha in pixmap color conversions (CMYK only).Tor Andersson
2018-10-25Fix asserts and checks in fast_xxx_to_yyy functions.Tor Andersson
fast_rgb_to_cmyk had || instead of && so always triggered incorrectly. Only throw, no need to both assert and throw.
2018-10-25Add and use fz_convert_pixmap_samples helper function.Tor Andersson
2018-10-25Drop SLOWCMYK path.Tor Andersson
If you want accurate CMYK, don't build with FZ_ENABLE_ICC=0.
2018-10-25Make alpha channel unmultiply and premultiply utility functions public.Tor Andersson
2018-10-25Guard loading embedded ICC profiles in images with FZ_ENABLE_ICC.Tor Andersson
Stops all the extra errors and warnings about missing ICC support.
2018-10-25Rename NO_ICC to FZ_ENABLE_ICC=0|1 to match other config.h options.Tor Andersson
2018-10-24Pass context to fz_paint_image to allow for printing warnings.Tor Andersson
2018-10-23Drop coords upon exception cloning path.Sebastian Rasmussen
2018-10-23Drop pixmap upon exception allocating draw device.Sebastian Rasmussen
2018-10-23Remove unnecessary exception handling.Sebastian Rasmussen
2018-10-23Drop hash table upon exception.Sebastian Rasmussen
2018-10-23Fix cleanup upon exception in the tiff filters.Sebastian Rasmussen
2018-10-23Remove extra blank lines.Tor Andersson
2018-10-23Dynamically allocate colorspace name, to allow arbitrary lengths.Sebastian Rasmussen
2018-10-23Remove unused variables in output-pcl.cTor Andersson
2018-10-23Add fz_write_pixmap_as_data_uri helper function.Tor Andersson
Also include "data:" schema in the data uri for fz_write_image_as_data_uri.
2018-10-23Allow SVG output to keep ID numbers unique across pages.Tor Andersson
This is required if embedding multiple SVG documents in a web page, for example.
2018-10-23Don't rely on CSS classes in HTML5 text output.Tor Andersson
This allows the output to be more easily embedded in other HTML documents.
2018-10-18Bug 699971. Fix bad read of mask type from display list.Robin Watts
We pack the mask type and the color parameters into a byte. We were unpacking it incorrectly, resulting in all masks being treated as luminosity ones.
2018-10-18Bug 699967: Follow ons.Robin Watts
1) Reset the margins at the start of each PCL job to avoid offsetting the page contents. 2) Fix height/band_height confusion in mono band writing.
2018-10-18Bug 699967: Fix crash with wide format output to color PCL.Robin Watts
Writing to wide format output was causing uncompressed lines of more than 32K to be written to a 32K buffer. I now recognise that there is an inherent limitation in PCL where image data can't be larger than 32K, so we'll have to split page output into subimages and hope they register well enough. This new commit does that (and solves the overwrite). I am seeing problems when feeding the output from this into gpcl due to the delta compression. We believe this is a bug in gpcl, and is being investigated as bug 699969.
2018-10-15Update lcms2 to lcms2mt.Robin Watts
Pull in the latest changes from mainline lcms2, and bugfixes from gs. This should now be the definitive version.
