1. Win32Lib & Bitmaps or maybe GIF's

Hello Fellow Coders,
I was wondering if anyone has researched the ability
to bitBlt and transBlt GIF files (if possible)?
I am pretty sure that to use the GIF file Format you
would need a liscence. Am I right?
I am extensively useing bitmaps and have found that over
time (to include these bitmaps with my program) the expense of HD space =
is too great.
Does anyone have an alternative to oversized images
other than zip archives?
If I were to use JPEG what if any restictions would apply?
Is it possible to use this format with Win32Lib?
I want to shave some bytes by-way-of graphics and need
some ideas.
I cant use Euphoria bitmaps because of the limitation
of being only 256 color depth (8 bit)
Thanks in Advance all !

I think that the Portable Network Graphic (PNG) format is a great
alternative to GIF. It is a lossless format (JPEG loses info with more
compression), it has good compression (using zlib) and does more than 256
colors (a limitation of the GIF format).
At one point I started wrapping libraries for JPEG and/or PNG support for
Win32Lib but like most of my projects, I lose interest or free time before
completing the task. I'll see about finishing up the PNG lib since I am
more interested in the format....
For more info on PNG see http://www.libpng.org/pub/png/
and for a library see http://www.libpng.org/pub/png/libpng.html

You'd need to convert the GIF file to a windows bitmap as you
load it, there are some library's to do this (by Mike Carroll and
Michael Bolin) in the archive:

Only if you want to output to GIF format, it's free if you just read
them in

GIF files and JPEG's ;)

No restrictions, JPEG is totally open, not sure how you load JPEG files
though

GIF's are also limited to 8 bit

5. Re: Win32Lib & Bitmaps or maybe GIF's
I've run into the same problem with a project I'm doing. However I'm not
concerned so much with the disk space the graphics will take up, more with
the effect of loading three megabytes of bitmaps into memory. The way I
understand it, whichever graphics format I use, they will still need to be
converted to bitmaps once loaded in order to display them (with BitBlt etc).
Am I wrong? I reluctantly decided to just use 256 colours in the end (only
one meg of graphics).

FYI:
I'm making good progress on wrapping a library that will support the
following formats:
BMP files [reading, writing]
ICO files [reading]
JPEG/JIF files [reading, writing]
KOALA files [reading]
Kodak PhotoCD files [reading]
PCX files [reading]
PNG files [reading, writing]
PNM files [reading, writing]
Sun RAS files [reading]
TARGA files [reading]
TIFF files [reading, writing]
WBMP files [reading, writing]
Unfortunately, it will not be very 'generic' since I am using Win32Lib to
wrap the functions. But to Win32Lib users looking for support of more
image formats, rejoice!
I'll try to get a beta out by the end of this weekend...

Great, you seem to have covered most of the formats
contained in JASC PaintShop Pro.
I for one will rejoice at seeing them implemented.

Wow, way great!
Is it possible to do comparisons of pics, say for instance, read regions of a
gif to do pattern comparisons? So if one gif is a pic of a plate, and a plate
is occupying most of another pic, can Eu (your lib) be used to say there is
a plate in the second pic?

No, nothing that fancy. So far I've wrapped functions that will read the
files... and another function will create a DIB that can be displayed using
Win32Lib's 'drawBitmap' function. Unfortunately, the lib doesn't support
GIF's (Unisys copyright?), however, I've previously done some work with the
GIF library in the RDS archives so I could easily incorporate it into the
lib.
But functions will be provided which allow you to directly access the image
palette and bits so you could conceivably expand on the functionality...
Various color reduction and image effects will also be included.
In case anybody is wondering, the library I'm wrapping up is FreeImage.
http://home.wxs.nl/~flvdberg/
This is an easy to use, high level library, but I was only looking for a
general purpose image decoder for use in our Win32Lib programs (especially
support for JPEG and PNG). That and I wanted something that would be easy
to wrap (which it is... 8^)
