(...) I could provide a MLCad specific bitmap element very quickly. This element could be sized, moved and rotated. Internaly MLCad would handle this element like a normal quad.

(...) BMP2DAT can be used as a start, but it's not generally viewed as a good final product. Other programs have an option to use a bitmap as a background image. That can be useful for drawing patterned parts. Steve (24 years ago, 30-Aug-00, to lugnet.cad.mlcad)

Well, assuming it's left in some bitmap format, I could update LDView to use a texture map to draw the image. However, adding bitmaps to a .DAT file in some ASCII format is going to make for some really big .DAT files. Alternatively, of course, it (...) (24 years ago, 31-Aug-00, to lugnet.cad.mlcad)

I was just thinking on offering something similar to bmp2dat. The other thing always is that it should be compatible to Ldraw and than you have to convert the bmp to something which LDraw can use too. Michael Travis Cobbs <tcobbs@san.REMOVE.rr.com> (...)
