Thanks, but i can't understand how this can be done. Is it possible to make so in DLTCP? And how? Or BAM workshop?

For best compatibility with all games, the transparent color should be pure green RGB(0,255,0) and the shadow color (if applicable) should be pure black RGB(0,0,0).  Depending on the tool you use to turn the images into a BAM, it may be necessary to have these transparent and shadow colors located at palette entry 0 and 1 respectively in your images.

Thanks, i tried, but the green background doesn't disappear at all:

The .bmp's color 1 in it's palate... that's considered to be "invisible", as it's the transparent color. In your picture it's the black, and in the other it's the paper color... but as .bam's files don't use full color blacks in everyframe, to increase data control in a multiframe data constructs.

What you can do is use a better conversion tools. Or use a different editing one. Say BAM workshop 2.

Thanks, yes, i have installed the latest version of Bam workshop 2. But it doesn't open PNG files:

And if i import BMB here, and save to BAM, the background in it is not transparent .

Hi, could anyone advise me please about bam-files.
Sometimes, when i import a new bam-file to the game, spots around the image appear:

It doesn't happen with every new image/bam. And i can't understand, on what it depends.

I don't know if i create bam-files properly, but this is my way:
1)I have a png-file painted
2)I place it on a completely black background and make bmp-file with proper size (about 55х55 px) and save with 32 bit in photoshop (i have tried another parameters, but it don't help).
3)I upload this bmp to DLTCP and make bam-file. 

It works well very often and most of the images look well. But sometimes there are black spots. As i understand, black background works as   "chromakey", and game and DLTCP delete it, but sometimes not completely.

I found a solution - i compress bmp file in MS paint to 256-colored bmp. Black spots disappear afterwards, but the quality suffers. Sometimes it is not seen, but in this case, for example, it is not pleasant:

Do you have any advice?

I have a programm bam workshop. But when i import bmp or png to it and save as BAM, DlTCP can't open it afterwards((.

Thank you
