Sorry for my English )
I have several jpg files

I tried it

Is it ...

Thank you.
Did prefix "PNG32:"

Good afternoon.
Sorry for my English - translated the interpreter.
Such a problem.
When I change the size of png icons on tiny 15x15 pixels, then change the format icons - colors are indexed, but must be in RGB format /
How do I fix this?

Good afternoon.
Weácan and you can do something like the program to understand the file names on the Cyrillic (Russian and Ukrainian)?

/R works! Thank you. I do not know what sort relates to the functions of Windows.
can recommend you the first line in it withdraw? )

Thank you for your answers.
To solve the problem - I found the console program nconvert.
And with the help of her overtake BMP to PNG and vice versa with the persistence transparency necessary and alpha layer.
Unfortunately I do not know how to lay out here its BMP files that you can see them.
Try ...

when I do so
convert 1.png 1.bmp
I get a bmp file with alpha channel v1
if I open this file in Potoshop and resave in the bmp, I get a bmp file with alpha channel ver 3

If you do so
convert 1.png BMP3: 1.bmp
I get a bmp file without an alpha channel v3

This information gives FastStone

I read that it is impossible, but it can all still have some way either.
And then I had two days writing a program, but only now noticed that the obtained bmp files with alpha channel can not be read, because they have a version 1.
A need - 3
Help, please!

Pity.
Thank you for your reply.
We look forward to full support BMP
