Hi, this is a call to all plug-in developers and everyone else who wants to help. The development version of The GIMP knows about image resolution and real-life units for a longer time now. But still a lot of plug-ins don't make use of this functionality. For consistency all plug-ins that touch dimensions or resolution should take care about correctly setting the image resolution and if they ask for lengths, size or dimensions they should do this using real-life units. Libgimp does provide functions for all this. The resolution and unit of an image can be retrieved and set through it. For interactive plug-ins there's the gimp_size_entry widget that handles most resolution stuff automagically. To help plug-in authors to change their plug-ins accordingly I have recently changed the Grid plug-in as a simple example. I have put a lot of comments into the code to make it easy for other developers to copy from it. The updated Grid code is in CVS. If you don't have CVS access, grab it from http://sven.gimp.org/files/grid.c Other plug-ins that already use the new functionality and can be used as examples include: - screenshot - tiff - png - newsprint - jpeg - psp Some plug-ins that come to mind that absolutely need the new functionality are: - print - ps - all blur plug-ins - most distort plug-ins - xscanimage This is not a very difficult task and an easy way to receive respect from the GIMP community, get famous and eventually rich. So, fire up your favorite editor and keep those patches coming... Salut, Sven
