Hi,
i have written an operation for gegl that writes OpenEXR float images, since
i noticed there does not seem to be one already and i could use it. This
version is quite usable within it's limitations. Limitations currently are:
- writes only 32 bit linear floating point images.
- only writes Y or RGB images with optional alpha.
- does not make use of OpenEXR specialties like layers, mipmaps
and multichannel.
It does support the tiled format; for simplicity, however, tiles are always
square.
I would like to see it included in the distribution; for now i have attached
a patch, which creates a new file gegl/operations/external/exr-save.cc and
makes a modification to the Makefile.am to build it. The patch is against
version gegl-0.1.6, but works with the git-version (as of 2011-07-13), too.
Sorry, for not providing a URL, but i do not have one right now.
The built operator is named 'gegl:exr-save' and has two properties:
path (string) - the filename to write to
tile (int) - the width of a tile (used for both x and y size);
the default is 0, which means a scanline file is written.
Any comments or suggestions for this?
Greetings - Rasmus
