How can one go about drawing a PICT resource grayed out? I tried setting the penpattern to gray and calling drawpicture, but this doesn't work. Has anyone done this before? I have a PICT button and i need to have some way of graying it out when the button is inactive. Michael O'Rourke

An easy way to achieve the desired effect is to gray out the image AFTER drawing it, by using the patBic penmode. For example: void DrawGrayedPict(PicHandle ph) { Rect r = (**ph).picFrame; DrawPicture(ph, &r); /* Here we go . . . */ PenMode(patBic); PenPat(gray); PaintRect(&r); } This, by the way, is the same technique used to draw grayed-out text in menu items, buttons, and so forth.

This should work on both Classic and Color Quickdraw Systems. ____________________________________________________________________ Have a day. :^| Murat N.

Draw the picture, and then draw a gray rectangle over it using a Bic pen (i.e. FillRect with patBic). Al
