[STR New] Link: http://www.fltk.org/str.php?L2310 Version: 1.3-feature It's great ! I started testing the first version (on Windows only), but didn't find the time to write my comments here. The lack of "normal" FLTK clipping was the most problematic point and I thought about the need for better scaling (other than the matrix functions) and positioning. I tried (and succeeded) drawing normal widgets and even the whole program window with some tricks, but the failed clipping made it unusable for general functions (e.g. missing text in the sliders). This is all solved with version 2 :-) Really good work so far! Version 3 added a simplification for widget printing, but I found that I would often need x/y position parameters, if I wanted to draw widgets without calling setorigin() frequently or messing with the widget coordinates (that were taken from an ordinary, existing window). Thus I added this in my test program (for version V2): static void print_widget (Fl_Widget *w, int X, int Y) { int ox = w->x(); int oy = w->y(); w->position(X,Y); w->damage(FL_DAMAGE_ALL); w->draw(); w->position(ox,oy); } This ensures that widgets can be drawn at arbitrary positions in the print area (X and Y are relative to setorigin()). The position is restored after draw() to be sure. AFAICT this doesn't work for windows though (x/y coordinates are ignored); therefore it might be better to adjust the widget positions by changing the origin accordingly in Fl_Native_Printer::printwidget(). Maybe. It would also be a good extension to have a method to get the current x_/y_offset (origin) for applications. Currently not working in my test: Transparency (real alpha or transparent pixels like in Fl_Pixmap). I didn't test real alpha channel images yet. Is there a chance that transparency can work with printing devices? I'll post my demo program that shows the effect with a pixmap. Look for porsche.cxx - the demo source porsche.pdf - the output when printing only page 2 (of 3 identical pages) You will need test/pixmaps/porsche.xpm for it to work. More comments to follow in a different posting.
