What will VB6 accept? 64x64 in 256 colours? And how will it look on XP
and Vista desktops? The old icons are looking bad on Windows 7.
I don't know whether VB will *not* accept anything
as an icon resource, but I've never tried anything but
a 256-color 32x32.
You didn't mention what the old icons are. I'm guessing
that they're probably 16-color/4-bit. That used to be
common. With full-color display you can probably use
8, 24, or 32-bit. I doubt there's much difference. 256
colors is not very limiting with such a small image.
I've never used anything bigger than 32x32. I know that
on Vista 7 they can go up to 128x128... or is it 256x256?
But I've never tried that and I have no idea of where such
usage would be relevant. (I don't even know where 64x64
might be used. Maybe on very large Desktops?)
I have drawn one simple image in a bitmap, but it has rough edges. I
could do this better with a graphics program. I wonder if I should
download IrfanView or something else.
IrfanView can do a lot, but it's limited as a graphics
editor. If you don't have such an editor I'd suggest
downloading the GIMP. It's free. It's pretty good.
The GUI is a bit funky. There's no MDI parent window.
That's supposed to change in the next version. Other
than that it seems to work well.
Paint.Net is supposedly pretty good, too, but it requires
that you install a recent version of the .Net runtime.
That's something like 1/2 GB if you don't already have
it installed. Other than that, there are lots of free
programs that come with cameras, scanners, etc., but
most are not much good. And then there are the pro
programs like Photoshop -- very good but overproduced
and absurdly expensive. (I know a professional artist
who uses Corel instead. I don't know how the price of
that compares to Photoshop. I use Paint Shop Pro, but
they sold out to Corel, and it got extremely bloated even
before that happened.
Someone else might have better ideas about graphic
software. For myself, PSP5 is good enough for now. Aside
from that I'm waiting for the next version of GIMP to come
out and hoping that will be good enough to drop consideration
of all other options for good.
If you drew the image and it has rough edges than
you probably want to redraw it with anti-aliasing. Most
graphic editors will provide that option. It works by
blending the border pixels with the background color
so that you don't get sawtooth edges. That's the kind
of thing I had in mind when I said a graphic program
is much easier than drawing 1 pixel at a time.
