Re: [Libpgf-user] Problems building pgf tools on Ubuntu 10.10

[Leith B. <le...@le...>]

Hi,

I tracked down the problem. Ubuntu 10.10 has a newer version of
FreeImage than the one included with pgf. As such the FreeImage
headers in the pgf include directory conflicted with the installed
FreeImage binary.

It is a *really* bad idea to include library header files in Linux
source distributions.

I fixed this by removing the include folder from makefile.am. Also now
that FreeImage supports unsigned width and height I modified the
CImage::Create function to use unsigned int instead of int, and
removed the (WORD) casts.

I also modified the second Create function to use unsigned int for bpp
as it is a bad idea to mix unsigned/signed stuff.

The PNMPlugin.ccpp also likely needs an update to use unsigned ints
with the updated FreeImage functions. There are some more
signed/unsigned conversions in here too.

I now have the program compiled.

Unfortunately it appears the program won't open my 9.9GB TIFF data
that I want to compress:
Error: Could not load source file.

Does the FreeImage library handle BigTIFF files? ie files > 4GB.

If it doesn't I am going to have to write some sort of plugin for GDAL
to convert my files.

Does PGF define a format for storing geospatial information, or will I
have to define my own? (Possibly create a new standard for it)

Thanks,
Leith Bade
