2016-01-13Add lots of consts.Robin Watts
In general, we should use 'const fz_blah' in device calls whenever the callee should not alter the fz_blah. Push this through. This shows up various places where we fz_keep and fz_drop these const things. I've updated the fz_keep and fz_drops with appropriate casts to remove the consts. We may need to do the union dance to avoid the consts for some compilers, but will only do that if required. I think this is nicer overall, even allowing for the const<->no const problems.
2016-01-05Add pixmap struct accessors.Tor Andersson
2015-12-28Rename fz_image_get_pixmap to fz_get_pixmap_from_image.Tor Andersson
2015-12-15Rename fz_output_x to fz_write_pixmap_as_x etc.Tor Andersson
2015-12-15Rename fz_write_x to fz_save_pixmap_as_x or fz_save_bitmap_as_x.Tor Andersson
Separate naming of functions that save complete files to disk from functions that write data to streams.
2015-12-11Use fz_output instead of FILE* for most of our output needs.Tor Andersson
Use fz_output in debug printing functions. Use fz_output in pdfshow. Use fz_output in fz_trace_device instead of stdout. Use fz_output in pdf-write.c. Rename fz_new_output_to_filename to fz_new_output_with_path. Add seek and tell to fz_output. Remove unused functions like fz_fprintf. Fix typo in pdf_print_obj.
2015-02-17Add ctx parameter and remove embedded contexts for API regularity.Tor Andersson
Purge several embedded contexts: Remove embedded context in fz_output. Remove embedded context in fz_stream. Remove embedded context in fz_device. Remove fz_rebind_stream (since it is no longer necessary). Remove embedded context in svg_device. Remove embedded context in XML parser. Add ctx argument to fz_document functions. Remove embedded context in fz_document. Remove embedded context in pdf_document. Remove embedded context in pdf_obj. Make fz_page independent of fz_document in the interface. We shouldn't need to pass the document to all functions handling a page. If a page is tied to the source document, it's redundant; otherwise it's just pointless. Fix reference counting oddity in fz_new_image_from_pixmap.
2015-02-17Rename fz_close_* and fz_free_* to fz_drop_*.Tor Andersson
Rename fz_close to fz_drop_stream. Rename fz_close_archive to fz_drop_archive. Rename fz_close_output to fz_drop_output. Rename fz_free_* to fz_drop_*. Rename pdf_free_* to pdf_drop_*. Rename xps_free_* to xps_drop_*.
2014-08-20Add full-page color tinting option and key binding to X11 viewer.Tor Andersson
win32 supports tinting, but cannot change the color from the default.
2013-11-04Make sure declarations come first. This would not compile with default ↵Michael Vrhel
windows settings.
2013-10-31Fix segv bug in clear_pixmap_with_value functions.Tor Andersson
Image masks don't have a colorspace; check before dereferencing.
2013-10-31Special case clear_pixmap_with_value for CMYK colorspaces.Tor Andersson
2013-10-31Add CMYK support to PAM output.Tor Andersson
2013-10-11SVG: Fix clip stack handling etc.Robin Watts
fts_09_0919.pdf shows up some silly mistakes in the clip stack handling and in the handling of 0 sized pixmaps. Simple fixes.
2013-10-10SVG: Fix fts_01_0106.pdfRobin Watts
A gradient fill that doesn't fill the bbox should be see through (unless background color is set, but we'll worry about that case when I find an example file that uses it). Arrange for the pixmap we draw the gradient fill into to be transparent initially. Also ensure that when we convert to png we preserve transparency.
2013-10-10Add fz_new_png_from_pixmapRobin Watts
This accompanies the function formerly known as fz_image_as_png (now renamed to fz_new_png_from_image).
2013-10-09Fix typo in pixmap handling.Robin Watts
When creating a png, a typo meant that we ALWAYS converted the pixmap even when we had an rgb or grayscale image on entry. Also, treat mask pixmaps (no colorspace) as gray.
2013-09-27add support for .tga output to mudrawSimon Bünzli
SumatraPDF's testsuite uses Targa images as output because they're compressed while still far easier to compare than PNG and have better tool support than PCL/PWG.
2013-09-13Fix various compile warnings spotted by the cluster.Robin Watts
2013-08-30Use RLE coding scheme for glyph bitmaps.Robin Watts
Rather than generating fz_pixmaps for glyphs, we generate fz_glyphs. fz_glyphs can either contain a pixmap, or an RLEd representation (if it's a mask, and it's smaller). Should take less memory in the cache, and should be faster to plot.
2013-08-30Add simple banding to mudraw.Robin Watts
The most complex part here is to ensure that we can output various bitmaps in bands.
