simple image conversion on files
Hello guys,
I am really frustrated. I have been trying to find a script that will do this for me but can't. I basically have thousands of .png files and I want to convert them to .bmp . It's as simple as that. The steps I take to do this in gimp are:
1) Open the .png file.
2) Goto file save-as.
3) Change the extension from .png to .bmp and save. (leaving the "advanced settings" to default.. that is save as 32bit "ARGB")

An example image is here:

I want to do repeatedly for all the image files. Can someone please help me. It's so simple but I don't really know much scripting.

Hi, thanks for help. I downloaded and the did the conversion like you said but the file size is not exactly the same as from gimp. I want to preserve the alpha channel and the output should be "ARGB" and not even "RGBA". I need this to do some more manipulation later. please tell me if you know how to do that.
