Ignore invalid page references in outlines.
This was shown by a file that had [null 0 0 1] as a link dest.
Attempting to parse that threw an error, which caused the whole
outline load to fail.
|
|
|
|
The hacky stdin workaround has never worked satisfactorily. Just nuke it.
|
|
Move the definition of the structure contents into new fitz-imp.h
file. Make all code outside of fitz access the buffer through the
defined API.
Add a convenience API for people that want to get buffers as
null terminated C strings.
|
|
Correctly transformed target coordinates for PDF.
Target coordinates for EPUB and HTML.
|
|
All link destinations should be URIs, and a document specific function
can be called to resolve them to actual page numbers.
Outlines have cached page numbers as well as string URIs.
|
|
In addition, make all callers passing 0 as a point pass NULL
instead.
|
|
As fz_drop_*()/fz_free() all must handle NULL.
|
|
|
|
Only Windows and Android have form filling text input implemented
properly so far. Neither of those build using the Makefile. We
therefore disable text input in Makefile built viewers.
|
|
Use a flag in the pdf_annot struct instead.
Don't pass pdf_document to annotation edit functions.
|
|
Account for used space before comparison, not after.

Since the removal of the begin_page device function, structured
text extraction has been unable to correctly establish the
mediabox for extracted pages.
Update the fz_new_stext_page call to take this mediabox
information. This is an API change, but hopefully most people
are calling fz_new_stext_page_from_page or
fz_new_stext_page_from_display_list which are updated here to
cope.
Update all the apps/tools to behave properly.

We want to turn pdf_page into a thin wrapper around a pdf_obj, so that
any updates to the underlying PDF objects will be reflected without
having to reload the pdf_page.
|
|
We had these reversed. Doesn't matter too much with a mouse, but
matters a lot more on a touch screen when the same signals are
used to do pinch zoom.
|
|
To return the proper size from fz_bound_display_list, which has been
broken since the begin_page device call was removed.
|
|
Allows us to remove the out parameter 'transform' from fz_begin_page.
|
|
This silences the many warnings we get when building for x64
in windows.
This does not address any of the warnings we get in thirdparty
libraries - in particular harfbuzz. These look (at a quick
glance) harmless though.

If a file cannot be saved incrementally, then don't accept that
as an option. In practise this means if someone asks to save
a file incrementally, and it was repaired, or it uses encryption
then throw an error.
Add a new function to ask if it's safe to save a file incrementally,
and use that in the appropriate places.

fz_pixmaps now have an explicit stride value. By default no change
from before, but code all copes with extra gaps at the end of the
line.
The alpha data in fz_pixmaps is no longer compulsory.
mudraw: use rgb not rgba (ppmraw), cmyk not cmyka (pkmraw).
Update halftone code to not expect alpha plane.
Update PNG writing to cope with alpha less input.
Also hide repeated params within the png output context.
ARM code needs updating.

Spot https and pass to curl. If curl isn't built with https
support we'll fail, but then we'd fail anyway without trying.

Resources are defined before they are used; so it's only logical to
have the resource dictionary before the content buffer in the argument
list.
|
|
Also remove redundant assignments.

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

In preparation of adding pdf_write_document that writes a document
to a fz_output stream.
|
|
Separate naming of functions that save complete files to disk
from functions that write data to streams.
|
|
Less risk of confusion with the text type used in the device interface.
|

Slow, but at least it won't crash.
Fix for bug 695742.

arrays
The list box and combo box can have values that are 2-element arrays. The first element
is the "export" value and the second element is the value that should be shown
in the list box UI. This fix ensures that we get the proper value to show in the UI.
Also, it adds the option to get the export values. These are needed if you wish to
update the field dictionary's V (value) entry, which is the currently selected values(s).
This fix works well with gsview. The other viewers will now display the proper content
in their UI, (unlike before this fix) but may need a bit more work to ensure that the
proper V (value) is updated with changes in the selections. In addition, we add
selection rectangles to the selected list box items.

It is conceivable that this might run into problems on 32bit
builds with suitably large bitmaps, but, hey, don't zoom that
far.
|
|
Include pdfapp.h after the UNICODE defines to ensure that the
correct version of the Windows string functions are used.
Thanks to Tamir Evan for this workaround.
