#31 Make it easer to remove plug-ins
FreeImage handles a lot of file formats from very broad fields. Many of these come with fat libs.
When file size is an issue (embedded/mobile) this becomes a problem.
Make it possible to easily exclude some plugs form compiling.
It seams there are some dependencies that make this unnecessary involved:

Also the way do remove plugs must be documented. Even if it is the current way (with depend. solved hopefully)

Testcase (test images not included)
Attached a patch witch make it easer to remove plugins.
To remove a Plugin:
1. Comment the relevant addNode() in Plugin.cpp FreeImage_Initialize
2. Remove the plugin code (and its lib)
These can be made to be #defined controlled, but I dont think the mess is worth it.
What the plug does is force using the FREE_IMAGE_FORMAT enum values for the Plugin lookup, without assuming both value and position (in the enum) match, as it was before.
This means that if you remove (comment out) a plug, and what to iterate over all fif-s, use the new FreeImage_GetLastFIF() instead of FreeImage_GetFIFCount():
for(int i=0; i < FreeImage_GetLastFIF(); ++i)
{
FREE_IMAGE_FORMAT fif = (FREE_IMAGE_FORMAT) i;
...
}
Patch (3.14.1) fixed load and save
I missed changing in Plugin.cpp
line 401 and 473 the load and save routines.
They used FreeImage_GetFIFCount with is incorrect - fif can be any number and should be checked against FreeImage_GetLastFIF
attached a new patch
