Yeah you're right, thanks. I divided instead of multiplying.

As to the depth of the pixmap, it fails when loading so I can never get to the point to use the QPixmap::depth() function. The only data that the Locals and Expressions window displays for the image information is the following; width: 2000, height: 2000, nbytes: 16000000, format: 456327200, data: 0x6bcce780. Would I be wrong to assume that nbytes is the number of bytes? In any event, not sure that any of these values represent the depth.

But, thanks to your assistance, I've eliminated the SIGSEGV issue (at least for now) and now receive "can't find linker symbol for virtual table for `QPixmap' value" in the application output. I'm going to do some searching to see I if can figure this new one out. I'm sure I'll post again if I can't. So d_stranz, thank you very much for your support to date.
