This is a simple task that involves nothing but operations that are already available and accessible through the PDB. I would suggest that you use a GIMP Python or Script-Fu script to perform this task. But of course you can also do this in C if you prefer that.

So what I'm basically trying to do is turn this image: http://mat.ulaval.ca/~fgingras/misc/1.png into this one: http://mat.ulaval.ca/~fgingras/misc/2.png Do you have to do it on hundreds of images? A simple script will suffice and you could use gimp in batch mode. Or even use Imagemagick to do scaling. In gimp in script-fu you'd use gimp-drawable-transform-scale-default, if I understand what you are trying to do. If the images are coming from a font you could also have the font scaled before rendering it -- e.g. use fontforge, or just assign a new fontmatrix in fontconfig (assuming Linux). (if you're doing it for a Web page, note that most of the newest Web browsers can do transformations too now, using CSS) Hope this helps.

Is there any quick way to copy a drawable in memory, in order to manipulate it, and then manipulate the original again? Basically, what I'm trying to do is transforming an image in a few different ways (every time using the original image) using gimp_drawable_transform_matrix_default, keeping results in memory, and then putting all these results in one image, which would be sent back to the core. I don't quite understand what you are up to. All the data is kept in the core if you use gimp_drawable_transform_matrix_default(). You just tell the core to transform the drawable. No data is actually sent to the plug-in. I assume that the drawable your plug-in is working with, is actually a layer. Then the easiest way to create a copy of the drawable is to duplicate that layer.
