Greetings,

I have a gif image that I would like to make the white bg transparent. How do I do this in Image Majick?

Thanks!

convert input.gif -transparent white output.gif

assuming the background is pure 100% white

Thank you. I will see if it works.

I have this error when running this command :



What is the matter?

May be I have installed a wrong version of ImageMagick ?

Can not read Russian but assume that the problem is that the convert.exe that is being used is the one built into Windows not IM the convert.exe

I think the work around is to rename the IM convert.exe to somethng like IM_convert.exe and use IM_convert instead of convert in your camand. I wonder if you could add the path to the IM convert comand e.g. c:/program files/imagemagick folder/convert

I can translate (from Russian) texts into my error window (above) :

Window title : "Application error".

Text after red cross : "Application initialization error (0xc0150002). Press OK to close application".

No, it is not.

I run my command (convert.exe with parameters) from "Far manager" (a file manager like Norton commander) in curent folder C:\ImageMagick>
