I only get to work on gtk for a few hours a week. Here's my problem. My test data consists of rectangles. I need to scale this data to make it larger and smaller and to pan around.
So, to the data I apply a scale. starting scale is to make all data fit within the screen. I apply a shiftX and a shiftY, for panning. To each coord I apply a scale,shiftX/Y The Y value has to be inverted to the 0,0 is in left lower corner. I'm using gtk2.0.6 on a solaris 7 box, with gcc 2.8.1 I have the following functions to assist me with gc2wc -> graphics to world coords wc2gc -> world to graphics coords Any assistance with the logic would be appreciated :) Any source examples would be helpful. I'm not a student, I'm a perl person by trade :) _______________________________________________ gtk-list mailing list [EMAIL PROTECTED] http://mail.gnome.org/mailman/listinfo/gtk-list
