2016-04-04epub: Add stripped Charis SIL font to use as the default font for EPUB.Tor Andersson
2016-02-29Strip outlines when cleaning a pdf file.Robin Watts
Arrange to keep only the Outline entries that still refer to valid pages. More specifically, leaf outline entries that refer to pages that are elided are not dropped. Non leaf outline entries that refer to pages that have been elided are kept (for the sake of the children) but have NULL destinations.
2016-02-29Add mutool create tool, and PDF font and image resource creation.Michael Vrhel
Initial framework for creating pdfs This adds a create option to mutool for us to use in working on the API for creating content as well as adding content to existing documents. mutool create: Get page sizes and add them Start the parsing of the contents.txt file which may have multiple page information. Add the pages at the proper sizes. Further work on mutool create_pdf Remove the calls that were being made to the pdf-write device. Clean up several issues with the reading of the page contents. Get the content streams for each page associated with the page->contents Temp. created a pdf_create_page_contents procedure. I will merge this with pdf_create_page as there is significant overlap. Next is to add in the font and image resources and indirect references. Include pdfcreate in build Merge pdf_create_page_contents and pdf_create_page Add support for images in pdfcreate This adds images to the pdf document using a function stolen from pdf-device (send_image). This was renamed pdf_add_image_res and added to pdf-image. Down the road, send-image will be removed. Prior to that, I need to work on making sure that multiple copies of the same image do not end up in the document. Code was also added to create the page resources to point to the proper image in the document. Next fonts will be added in a similar manner, then I will work on computing the md5 sums of image and fonts to ensure only one copy ends up in the document. Then pdf-write will be reworked to use the same code as opposed to its current list of md5 sums that are stored in a device structure. mutool pdfcreate: support for WinAnsiEncoded fonts Added support for very simple fonts (WinAnsiEncoding). Methods added in pdf-font.c. Added first_width and last_width to fz_font_s and stem_v to pdf_font_desc_s. Ran code through memento with simple test of 4 page document creation including an image and a font. Fixed several leaks as well as buffer corruption issues (main changes in pdfcreate). Thanks to Robin for the help with Memento in finding leaks. Added StemV to pdf names as it was needed for the font descriptor creation. Fix for pdf_write_document rename to pdf_save_document Add resource_ids to pdf document structure The purpose of this structure will be to allow the search and reuse of resources when we attempt to add new ones to the document. Fix name changes from recent updates pdf_create branch updated to work with recent changes in master Initial use of hash table for resources To avoid adding in the same resource this adds a resource_tables member to pdf_document. The resource_tables structure consists of multiple fz_hash_table entries, one for each resource type. When an attempt is made to search for an existing resource, the table will be initialized in a brute force search for existing resources. Currently this is only set up for the image resources and accessed through pdf_add_image_res. If a match is found, the reference object is returned. If no match is found NULL is returned and the ref object created in pdf_add_image_res is added into the hash table. In this case, a command line such as create -o output.pdf -f F0:font.ttf -i Im0:image.jpg -i Im1:image1.jpg \\ -i Im2:image.jpg contents.txt will avoid the insertion of two copies of image.jpg into the output PDF document. CID Identity-H Font added for handing ttf This adds a method for adding a ttf to a PDF as a CID font with Identity-H mapping and a ToUnicode entry that is created using FT_Get_Char_Index This takes much care in the creation of the ToUnicode CMap to ensure that the minimum number of entries are created in that we try to use beginbfrange as much as possible before using beginbfchar. The code makes sure to limit the number of entries in a group to 100 and to not cross first-byte boundaries for the CID values as described in the Adobe Technical note 5411. Add missing file pdf-resources.c pdf-resources.c was missing and should have been committed earlier. Added to windows project file. Not sure where else it needs to be added for the other platforms. Clean up names and spacing Make sure that the visible functions have the proper namespace (e.g. pdf_xxxx) Also make sure we have a blank line prior to comment. Be consistent with static function naming in pdf_resources.c pdfwrite make use of image resource fz_hash_table The pdfwrite device now shares the structure that stores the resource images for pdfcreate. With this fix, pdfwrite now avoids duplicating the writing of the same images that are shared across multiple pages. Add missing file pdf-resources.c Initial work toward having pdfwrite use Identity-H Type0 encoding for fonts Finish of CID type0 Identity-H font for pdfwrite This adds in the proper widths which may have been stored in the source font in the width table (parsed from the W entry in the pdf file) or if the free type structure has its own cmap then we can get the width from free type. Widths are restructured into format described in 5.6.3 of PDF spec. Fix issue from conflict merging and multiple define of structure Clean up warnings and make mutool create use simple font

2015-04-06Update mutool subtools to use PDF_NAME_xxx rather than "xxx".Robin Watts
2015-03-24Rework handling of PDF names for speed and memory.Robin Watts
Currently, every PDF name is allocated in a pdf_obj structure, and comparisons are done using strcmp. Given that we can predict most of the PDF names we'll use in a given file, this seems wasteful. The pdf_obj type is opaque outside the pdf-object.c file, so we can abuse it slightly without anyone outside knowing. We collect a sorted list of names used in PDF (resources/pdf/names.txt), and we add a utility (namedump) that preprocesses this into 2 header files. The first (include/mupdf/pdf/pdf-names-table.h, included as part of include/mupdf/pdf/object.h), defines a set of "PDF_NAME_xxxx" entries. These are pdf_obj *'s that callers can use to mean "A PDF object that means literal name 'xxxx'" The second (source/pdf/pdf-name-impl.h) is a C array of names. We therefore update the code so that rather than passing "xxxx" to functions (such as pdf_dict_gets(...)) we now pass PDF_NAME_xxxx (to pdf_dict_get(...)). This is a fairly natural (if widespread) change. The pdf_dict_getp (and sibling) functions that take a path (e.g. "foo/bar/baz") are therefore supplemented with equivalents that take a list (pdf_dict_getl(... , PDF_NAME_foo, PDF_NAME_bar, PDF_NAME_baz, NULL)). The actual implementation of this relies on the fact that small pointer values are never valid values. For a given pdf_obj *p, if NULL < (intptr_t)p < PDF_NAME__LIMIT then p is a literal entry in the name table. This enables us to do fast pointer compares and to skip expensive strcmps. Also, bring "null", "true" and "false" into the same style as PDF names. Rather than using full pdf_obj structures for null/true/false, use special pointer values just above the PDF_NAME_ table. This saves memory and makes comparisons easier.
2015-02-03Update URW fonts.Tor Andersson
Add the new URW base fonts that include greek and cyrillic scripts. These new fonts remove the need for DroidSans as a generic fallback font.
2014-05-29Fix 694093: add vertical variant of CJK fallback font.Tor Andersson
Replace the DroidSansFallback TTF files with a TTC that has two fonts: The original and a copy where the OpenType 'vert' substitution lookup has been pre-applied by copying the uniXXXX.vert glyph data to uniXXXX.
