Hello again,
my application draws a vector map from coordinates text files directly by "disk" read. A map load or refresh is very slow. Has anybody experience with this? Is it the fileread function or the graphics display that is so slow? I draw with the standard form.xxx commands. No complex drawing, just a few lines. Would keeping the coordinates in memory (array) speed up a redraw?
Thanks
Andy
