PDF however is a neat subset, and although I know little of it, I suppose I could handle PDF saving with ADOBE docs - that is all of the bellow could be done for both PS and PDF. In the meantime, however, we will need the PDB API's for both vector and Text layers, I think them I should address these first. I will browse through the text-core today, to start to get a feeling of how it works. My idea of saving text as curves would be: - having implemented a "save vectors to postscript curves" (which I had done in python-fu for gimp 1.2), create a "vector from text" thouhgh the PDB, and them use this vector to save as postscript curves, filling with the text layer's color (which also need to come from the PDB API) Such a plug-in would need to know if a text-layer had been modified after it was stroke. Is there a flag for it already on the core? I understand that if there was no prevision for it, it may be hard to implement. /me switches to the GIMP, creates text layer, paints on it, and tries to edit the text, thus answering his own question. Good, it is there. We will need a PDB proc. for that too. You made no comments on the vector layers api, do you think they are feasible into 2.2? > "Joao S. O.
