Added warning messages for font substitutions. + +3.04 (2014-may-28) +------------------ +New text extractor. +Added the pdftohtml tool. +Added the pdftopng tool. +New trapezoid-based rasterizer core (for performance). +Generate appearance streams for Line, PolyLine, and Polygon + annotations. +Added the closeWindowOrQuit command, and changed the default binding + for ctrl-W from closeWindow to closeWindowOrQuit. +Implemented the new AES-256 mode (R=6, Acrobat X). +Add an object cache. +Added a small cache for object streams. +Modify PSOutputDev to use LZW compression instead of RLE, with a + fallback to RLE if the "psLZW no" setting is given. +Pdfinfo now prints page rotation info. +Modified ImageOutputDev, used by pdfimages, to output the masks and + soft masks used when drawing images. +Remove non-printable characters from error output, just in case they + might cause problems for the terminal program. +Added initial support for Code3of9 bar codes in XFA forms. +Added the mapExtTrueTypeFontsViaUnicode xpdfrc command. +Apply stroke adjustment to rectangular images and clipping regions (in + addition to strokes and fills). +Decode JPEG 2000 images at less than full resolution if the full res + image isn't needed (i.e., if the raw image is higher resolution than + the output). +Implemented knockout groups. +Removed t1lib support. +Added support for images with 16-bit components. +Rewrote the Dict class to use a hash table; as a side effect, this + handles dictionaries with multiple definitions for a key, which are + in violation of the spec, but Acrobat appears to handle. +The transformed line width computation -- used to implement the + minLineWidth setting, and the hairline threshold in monochrome mode -- + was incorrect. +Pdftops was not correctly handling the case where it couldn't find + a 16-bit font -- this led to crashes and/or invalid PostScript. +A bug in FlateStream::getBlock() was causing problems with narrow + images. +Use the correct _WIN32 define instead of WIN32. +Use copy-on-write for the clip path in SplashState (when doing gsave), + for performance. +Added a Solaris-specific entry to the ghostscript font search path. +SplashState was initializing line width to 0 instead of 1. +Abort processing on a content stream after getting 500 errors + (undefined operator, wrong number of args) -- this avoids very long + processing time for malicious PDF files using bogus RLE encoded + content streams. +Added the psUseCropBoxAsPage xpdfrc option; "pdftops -pagecrop" now + sets psUseCropBoxAsPage; "pdftops -pagecrop -paper match" now uses + the CropBox as the page size. +Re-architected the AcroForm support code into a separate AcroForm + module. +Fixed the handling of overprinting/transparency interaction, using + the CompatibleOverprint blend mode. +The TIFF predictor code for the 1-bit-per-pixel case was broken. +For triangle and patch mesh shadings (types 4-7) with color functions, + interpolate the function parameter not the color. +Check the fontFile/fontDir commands before (instead of after) doing + Base-14 substitution in PS output. +Correctly handle non-embedded TrueType fonts that have an Identity + ToUnicode mapping (display and PS output were failing). +Added support for XFA form rendering, including an "enableXFA" xpdfrc + setting. +Handle PFB Type 1 fonts when generating PostScript output. +Unwind any extraneous saved graphics state at the end of the page + (before drawing annotations). +Added some integer overflow checks in the GString class. +Handle 16-bit components in JPEG 2000 images. +ActualText spans can end without a valid font, in which case + TextPage::beginWord was crashing. +The Domain entry in function shadings wasn't being parsed correctly. +Fixed a bug in the JPEG decoder - successive approximation + (progressive mode) coefficients weren't being handled correctly. +Added a better infinite loop test to the xref parser. +When generating PostScript, merge reused TrueType fonts (if their + code-to-GID mappings are the same). +Tweak the Gouraud triangle shaded fill code to end the recursive + splitting if the triangles get sufficiently small. +Do bilinear interpolation when upsampling images. +When skipping extraneous image data from an inline image, look for + EI<whitespace> instead of just EI. +When writing to stdout on Windows, pdftoppm now sets the file mode to + binary. [Thanks to Robert Frunzke.] +Accept strings as well as names for the BaseFont entry in font + objects. +Removed the TEXTOUT_WORD_LIST config option (with the new text + extractor, this is always enabled). +Fixed a bug in the JBIG2 decoder (the TPGD context for template #3 in + readGenericBitmap was incorrect). +Rewrote the PostScriptFunction code for performance. +Handle 8-bit OpenType CFF fonts that are missing required tables in + the OpenType wrapper. +Handle tiling patterns with reversed coordinates in their bounding + boxes. +Added support for 64-bit file offsets, i.e., PDF files larger than + 2GB. +Optimize the code that rasterizes pattern-filled image masks. +Added support for Mac OS X system fonts (Base-14 only). +The backdrop color in luminosity-type soft mask groups was not being + handled correctly. +Modified behavior of "pdftops -paper match -duplex ..." - it will now + duplex consecutive same-sized pages. +Tweak the handling of degenerate fills ('moveto lineto fill') to + match Adobe. +Don't honor the OPM=1 setting with ICCBased CMYK color spaces. +Whole-word searches were treating certain punctuation (Unicode number + separators and terminators) as part of the word, e.g., searching for + "foo" would not match "foo,". +Use the TextString class everywhere it makes sense. +Removed the unnecessary segment sort in Splash (performance + optimization). +Handle hyperlinks that use Widget-type annotations. +Fix up the integer overflow checks to avoid issues with clever + compilers. [Thanks to Nickolai Zeldovich.] +Correctly handle streams with missing Length entries in damaged PDF + files. +Added a compile-time option (LOAD_FONTS_FROM_MEM) to load fonts from + memory rather than temporary files on disk. +Added the psRasterSliceSize xpdfrc option. +Fixed a case in the JPEG 2000 arithmetic decoder where extra data is + present in packet i, and needs to be saved for use in packet i+1. +Fixed a bug in the JPEG 2000 decoder related to images with fewer than + 8 bits per component. +Handle the case in PSOutputDev where slice size overflows a 32-bit + integer. +Add (partial) support for TrueType cmap format 2. +Always pass FT_LOAD_NO_BITMAP to FreeType -- bitmaps apparently fail + with rotated characters. +Support fonts specified in ExtGState dictionaries. +Annotations with empty Border arrays should not draw a border. +Fix the CMap parser to handle large CID ranges. +Check for Type 3 CharProcs that call q or Q before the d0/d1 operator, + and treat them as uncacheable. +Invert the selection color when starting in reverse video mode. +Device{Gray,RGB,CMYK} cannot be mapped via a resource dict. +Changed the PS output for masked images (explicit and color key + masking): use a plain old clip path instead of rectclip to avoid + array overflows. +Check the StemSnapH/V arrays when converting Type 1C fonts to Type 1 - + if there are any duplicate or out-of-order values, skip that + StemSnapH/V array. +Added the psMinLineWidth xpdfrc setting. +Fix an obscure issue in converting TrueType fonts to Type 42, related + to empty glyph descriptions (12 zero bytes). +Pdftops now reports an error if there were any I/O errors writing to + the PS output file. +Fix vertical text (CJK fonts) in PS output -- offset the character + origin correctly. +Increased the number of digits used by pdfimages for the image number + from three to four. +Handle right-to-left (e.g., Arabic) ligatures correctly in the text + extractor. +Added the -loc and -locPS options to pdffonts. +Extend the object parser recursion limit to cover Stream::addFilters() + / Stream::makeFilters() - to avoid another possibility of stack + overflow. +Disable FreeType autohinting, because it can fail badly with font + subsets that use invalid glyph names -- except in the case of Type 1 + fonts, which look much better with light autohinting. +Modified the rasterizer pipeline functions to process a scan line at a + time (for performance). +Removed VMS build support (it hasn't been updated in ages). +Removed pdftotext's '-htmlmeta' option (use pdftohtml instead). +PSOutputDev's font/form setup code, and pdffonts, were not scanning + soft mask groups in ExtGState dictionaries. +Invalid DCT input (e.g., from a damaged PDF file) could overflow the + dctClip array. +When upsampling an image mask or image with a large resulting image + size, do it in stream mode instead of prescaling the whole image + (to avoid running out of memory). +Added infinite loop detection to pdffonts. |
