+This tool is based on xpdf (currently 1.01). It uses the (mostly unmodified -
see below) xpdf PDF rendering engine. The Qtopia adaption was done with a new
OutputDev which renders directly to a QPixmap via QPainter calls.
Changes in 20020406:
- Font substitution handling improved.
- Unknown characters are simply ignored now.
- Fullscreen view added.
Changes in 20020407:
- Crash with FontName == 0 fixed
- Cleanup
- Prepare for CVS import
Changes in 20020408:
- Progress indicator added
- Problems with type 3 fonts (not fully supported by XPDF) solved
- Heavy optimizations in the image rendering code
-Changed in 20020413:
+Changes in 20020413:
- Fixed crash in find routine
- Stylus selection reworked
- Cursor-key navigation added
- Various crashes related to recursive calling of XPDF fixed
+Changes in 20020417:
+ - Fixed crash in XPDF regarding 0-length strings.
+ - Fast sqrt, rint and fabs functions added.
+
+Changes in 20020524:
+ - Ported to xpdf 1.01
+
Changes to xpdf:
- xpdf calculates nearly everything with doubles. Since ARMs are not equipped
with a FPU, all doubles have been replaced with a C++ class "fouble" (fixed
double), which operates on 32bit integers with fixed point arithmetic.
This gave a speedup of up to 800% for image rendering.
- No Font handling anymore - This means no embedded, no true-type, no type1-
fonts. The task to choose the right font is up to the Qt QFont class.
This works pretty well -- only Symbol fonts give problems.
- Everything that should be rotated (fonts, images) is simply ignored, because
a) the Qtopia Qt/E config has QPainter transformations disabled
b) the transformation is awful slow
c) do you really need rotated images on your iPaq ? ;)
ToDo:
- Clipping has been deactivated, because Qt/E had problems with QPainter
save/restore's with active clipping regions. I need to investigate this
in detail.
- Links are currently simply ignored.
Install:
- - xpdf-1.00
- Get the tarball for xpdf, version 1.0, untar it and ./configure it.
- (No special flags are needed for ./configure - it simply has to run)
-
- - qpdf
- Make sure your QPEDIR / TMAKEPATH variables are correctly !
-
- cd into the xpdf directory (xpdf-1.00) and untar the qpdf tarball. This
- should create a subdirectory qpdf.
- cd into this directory and start the script "./setup-qpdf". This
- incorporates the above mentioned patches into xpdf.
-
- Now do a make.
-
- Copy the files qpdf, qpdf_icon.png and qpdf.desktop to the appropriate
- directories on your iPaq or:
- If you want a ipk, just run ./mkipkg
+ - Qpdf is now fully integrated into Opie. For compilation and installation
+ instructions see http://opie.handhelds.org.
- compress / uncompress

+ If you run a normal familiar installation, the standard gzip (I tested
+ 1.2.4-33 ipkg) can handle the compression format used in PDF files, when
called as uncompress. The BusyBox version of gzip can _not_ handle this
old format.
- If you do not have a working uncompress installed on your iPaq, you can
- simply use the one in the contrib directory of the tarball (make uncompress
- a link to compress).
- [I could not find an official tarball for compress -- this is the SuSE
- version cross-compiled for ARM]
-
+ If you do not have a working uncompress installed on your iPaq, you could
+ simply use the old compress package.
+ (I could not find an official tarball for compress -- I used the SuSE
+ version cross-compiled for ARM for myself, but I will make an ipk soon)
+
Have fun ;)
