OK, then I'll do this that way. 
Also, d3dx9 provides support for multiple file format (PNG, TGA, BMP...). I 
assume I'll have to add those dependencies in the build process.

As far as I know GDI handles them, so you can use GDI functions here, and GDI 
in turn alredy has the dependency on the external libraries

Yes, but that would be very incomplete. GDI has only limited support for PNG and JPG files, and doesn't handle TGA at all.

Though this will be useful for DIBs, DDS and BMPs.

Just a friendly reminder, but when your patches get committed please do
remember to tell the devel list that the build dependencies have
changed.  It makes it much easier on package maintainers who otherwise
wouldn't know to build with the libraries that make your code actually
run ;)

Thanks,
