[vb6]Alpha Image Control v2 - Final Update (15 Jan 2012)

[petersen]

Thanks, both are of 1-bit-4-planes. The one in my zip earlier is of 4-bit-1-plane, so it suits to complement.

I've now added another 4-bit-1-plane file to the said zip. The newly added one is only different in image width. What for? To facilitate testing -- if byte alginment is not right, this one would not be displayed. (Because of it, I myself have to revise my 4 BPP Read subroutine a little bit for my own programs). So I thought it would be of use if you are going to implement 4-BPP PCX

Edited: Re your last message

....Everywhere I've read says 4bpp should come in as 1bpp @ 4planes....

That is the trouble. Seems a lot, but most are just copycats, and narrative only. In practice, I haven't come across any program actually praticing that. Have you seen even a single one? (If yes, please furnish the URL, I am curious)

On the other hand, I've seen good-quality shareware program(s) go for 4-bit-1-plane only, despite programs capable of saving 4-BPP are so rare.
