batch invert of images

[tim.schork]

Hi all,

I am trying to invert a series of images and to save these afterwards using the command line options in irfanview. I can get the invert to work, but not the saving of the images after the invert operation. I am sure this is very trivial thing, but for some reason I can't get it to work.

Here is what I have tried:

"C:\Program Files\IrfanView\i_view32.exe" C:\test.jpg/invert=C:\test1.jpg"

Can anybody help me out on this one?

You have to use the /Convert option which saves the image and closes Irfanview. So your Command line becomes

"C:\Program Files\IrfanView\i_view32.exe" C:\test.jpg /invert /convert=C:\test1.jpg"

Note: You do not need to have the space before a / but it makes it easier to read.
