First, look at the car in my other email. There are two tinters. Perhaps you are using cartoon-like stamps that tint with the crummy tinter. The crummy tinter converts the image to greyscale, then maps white to the tinting color and maps black to black -- with everything else falling in between. There are two ways to fix this. One choice is to eliminate the crummy tinter. This requires that some of the stamps be reworked. The nice tinter, used on the sedan for example, preserves all greyscale values from black to white. The most saturated part of the input image is mapped to the tinting color. Other parts of the input image map to somewhere between the tinting color and gray. The dragonfly stamp is greyscale, and thus would not change at all when subjected to the nice tinter. To work, it would need to have some color added. Another choice is to change the crummy tinter. It would need to map white to white, and black to black. Other values fall along a curve (parabola? hyperbola? circle?) that passes through black, white, and the tinting color. This would work for the tint magic too, assuming the curve is calculated only once on mouse-down. So, what curve should I use? What shade of grey should map to the tinting color? (choices: median, mean, mode, 127, 192, grayscale of tinting color...) Attacking this problem from both sides (changing stamps, and changing the crummy tinter) might be best. Does anyone want to do the stamps? Search for *.dat files containing "vector". _______________________________________________ Tuxpaint-dev mailing list Tuxpaint-dev@tux4kids.net http://tux4kids.net/mailman/listinfo/tuxpaint-dev
