Question about IIGS toolbox programming: How does one generate and use custom icons in a program? I have some fairly small (maybe 15 by 25 pixels) shapes that I want to draw in a desktop program. I tried plotting them point by point but that is much too slow, so I guess using icons would probably be the fastest way. What I need to know is, after I generate the hex representation, (from the icon editor IconEd), how do I actually make an icon out of it, and then how do I print that icon on the screen? Or would it be easier to somehow read the icons in from a standard icon file? I don't know. I'm using TML Pascal so Pascal examples would be greatly appreciated, although I also know C. Thanks very much for any help. -- Jeff Hartkopf

[...] The DrawIcon function in the QuickDraw Auxiliary toolset is one way. I'm not familiar with the output ("Save as Source"?) from IconEd, but DrawIcon takes a pointer to the icon data, an x and y location, and a code specifying how to color the icon & how to draw it (8 choices, corresponding to what the Finder displays for selected/not selected, online/offline, and open/closed, in all combinations). --Dave Lyons, Apple Computer, Inc. | DAL Systems AppleLink--Apple Edition: DAVE.LYONS | P.O.

Network Comment: to #8734 by pnet01!crash!boulder.colorado.edu!tramp!hartkopf Jeffrey, Have you heard of a program called "The Icon Editor" or TIE? It can be found on GEnie or CompuServe it's a shareware pgm. You can look at the icons you have in your system and edit it or build your own icons and copy it back into your system icon file. It also edits in several colors. I have a copy if you'er interested if I can figure out how to upload it on this system. Mel

Okay, here goes (please excuse any typos, it's kinda late, and this seems to be a noisy line). Page 17-3, section entitled "QuickDraw II Auxiliary icon record" reads: An icon is a small graphic object that is usually symbolic of an operation or of a larger entity, such as a document. The QuickDraw II Auxiliary icon recore indicates whether the icon is icolor or black and white, the size of the icon, the height and width od the icon, the icon image, andthe mosk controlling the appearance of the icon, as shown in Figure 17-1. Note: At the time of publication, this record had not been included in the APW interface file. Offset Field $0 & $1 IconType Word - Bit 15 set to 1 = color icon set to 0 = black and white icon $2 & $3 IconSize Word - INTEGER; number of bytes in icon image $4 & $5 IconHeight Word - INTEGER; height of icon in pixels $6 & $7 IconWidth Word - INTEGER; width of icon in pixels $8 - $x IconImage x Bytes - Icon image; IconsSize bytes long, each row of pixels is 1+ (IconWidth - 1)/2 bytes wide $x - $y IconMask (Same as above) That's all there is on 17-3, 17-4 goes on to talk about how the displayMode, hich controls how the iconMask is applied. Hope this has been of some help. Jonah -- jstich@pro-avalon UUCP: crash!pro-nsfmat!pro-avalon!jstich ARPA: crash!pro-nsfmat!pro-avalon!jstich@nosc.mil INET: jstich@pro-avalon.cts.com
