what you think? A question for GFX'rs, how do i transform to a 8bit bmp without color loss, i want to reduce filesize. Is there any other way?

Nice logo =]

I dunno if for example dUP like huffman compressed pics (you want stay on bmp, right?),

but just try things like Optimizing the color table.

1803 colors atm, I don't believe you need all, the human eyes could compare.

Just beautiful. No clue what you did pattern and..

Pattern was made with distortion wave to start off with

Looks good!

I converted it to an 8bit BMP for ya (attached), and it's about 50% smaller

To do this in photoshop with your BMP file open: open the image menu, mode, indexed color. In the pop up window you can make changes to the color depth if you want, but typically the default setting will provide the best quality image. Click the "Ok" button. Now, in the file menu select save as. In the pop up window that appears, change to BMP format and click the "save" button. Finally, another pop up window will appear which should have 8bit selected.... in the bottom of this window check the "compress (RLE)" option. This will convert and save your BMP file as 8bit.

Ok, an outstanding hint:

If you already have color palettes you can select them for your pic.

In the index color menu for example and palette go for custom.

Advantage: you reach better your size and compatibily

Disadvantage: You kill colors you maybe need.

Many programs bringing palettes with. I'm just testing eBabelizer Pro 6 by Equilibrium.

Looks interesting. with 26 pal-files inside.

Here start the real text:

I was bored, so already simulated what you would do. You can use drag'n drop in BitmapShrinker, but I suddenly recognized you will get an error. BMP Header defect. So once again save in PS or somewhere else. I'm sometimes too lazy waiting for PS load sequence and so making this kind of little jobs with irfanview or better xnview in seconds. Just open and save. Header should be fixed by automatic and with already one layer you don't need to care about a lost of others. A reason to call Adobe, hey ladies are you playing on your.. *g* ..sometimes anonymous bug reporting by email in hope don't have trouble in future. They waste energy in the reg-scheme, the PS core need.

After The Test with BitmapShrinker 1.0

Ok, comparing the three better candidates:

spez_125.bmp 24.354 Bytes,

spez_216.bmp 24.718 Bytes and

spez_252.bmp 24.862 Bytes

Damn, the grain increases very much

from spez_216.bmp you get a few with less, but anyway your soft looking is gone. Nah, in this case for the trash.

After the Test with XnView 1.91.1

Only the border is touched a bit on the right side, but nothing in the center, IrfanView is atm not on the machine, but think XnView was the only that give really what you need, because It has also better resizer mode Lanczos recommended than Bicubic, miniseconds slower with this size, but the quality stays better. I'm using it since XnView v1.68. I give you my cfg, If you like.

8bit-adaptiv-RLE.bmp 23.300 Bytes, meaned in the text above

8bit-dither-RLE.bmp 26.650 Bytes, produce not this yellow you have

After a Test with PS2 (had only that atm, switch soon back to CS3, but will give same result)

The index-selective.bmp looks good. hm.. small:

index-adaptive.bmp 23.620 Bytes but

index-selective.bmp 23.652 Bytes and

index-perceptive.bmp 23.624 Bytes looking ok, too.

At last a PhotoImpact test:

256opt-WeightGreen-MedianCut-Diff-RLE.bmp 26.886 Bytes

Ups, I forget Corel.

Made fun,

but JPEG or Gif have more possibilities, I think.
