Can someone give a hand and convert these BMPs to useful in-game BAMs? Maybe as an exchange I can try to create spell icons for someone. :)

Thanks. Is there a chance for doing that without loosing a quality? Icons colours are much simplified. I was using colours which were present in standard BG2 bams.

If you have php on your system, you could use this (quick and dirty =]) script: Attached File  img2bam.php   5.03K   150 downloads
If your image has less then 256 colours, it works on almost anything: gif, jpeg, png, bmp (not recommended, since php does not have native bmp support)... i think... (didnt really test it yet)

(BAM Workshop seems to fill the palette no matter how many colors are used in the image oO)

What's this? I don't recall seeing it before. Did you make it?

yes :)
with WeiDu I got interested in that kind of coding =)
PHP may not be the fastest solution for this, but well it's the language I'm most familiar with...

It's a bit of an unconventional solution, but if it works!

The only real problem I can see is that not many people have access to a webserver--and setting one up at your own computer just for using this might be overkill. With that in mind, it might be an idea to upload it to a website somewhere, where people can convert images through a file upload. We could do it right here on SHS, if you want to. :)

Why doesn't anyone speaking about the Item Graphics Converter from TeamBG ? (ouch, sorry , i'm a french guy :-/)

The site is down for the moment, but someone have surely the tool in his hard drive, as i have.

Here's the new version with RLE-Encoding: Attached File  img2bam.php   6.63K   110 downloads
It still doesn't work too well on images with more than 256 colors, but this is as far as PHP goes, i guess...

Now you can download it as an exe: Attached File  img2bam.rar   832.34K   174 downloads

@SConrad: I don't really think people will really use this script online, if they can download the exe... If you think otherwise, go ahead :]

.exe files are probably better than an online file upload, but you'll need to provide documentation for how to use the executable. :)

Just run the .exe from the CLI, so it won't close immediantly:

Usage:
       img2bam [Options] [Files]
Options:
       -C                No RLE-Compression

Can you assemble complex BAMs with this, such as creature animations? Ideally, I'd like an automated tool to dissemble and reassemble them (and even edit them a la TeamBG's Photoshop plug-in for MOS, PLT and TIS files, but that's another story).

The main problem with inventory (and description and spell) BAMs is getting the graphics to look right before assembling the BAM. Putting the BAM together is child's play compared with that.

Also, you should always downsample your graphics to 256 colours (8-bit) before putting the BAM together. I use PaintShop to do this with an octree optimised palette, error diffusion and colour bleeding reduction. This results in almost zero loss in most cases. If you try to automate this without those kinds of settings, your graphics can look incredibly crappy.

Actually, I never intended to do such a complex script, I was just playing around... But I'll have a look at it... =]

Of course, but PHP isnt that good at downsampling to a palette :/
