Is it possible to use fireworks cs4 batch command to change the same background color on multiple jpegs?

 

Thanks in advance,

Carl

    If you can find a command for this in the Batch Process dialog, then it can be done.

     

    However, I'd say this is unlikely. JPEGs are flattened, single-layer image files, so the concept of a background color doesn't really exist within that format.

    Sampling the top left pixel is an interesting idea.

     

    The other aspect of JPEGs that would make this tricky is that the color tends to be highly variable. Think of a photo, for example. The compression used in JPEGs works against the integrity of flat color—so even if you were dealing with a border around a photo, there'd be color variability where the border meets the image. You might have an easier time if you were working with an indexed color format like GIF or PNG-8.

     

    You can, incidentally, use Fireworks' History panel to create command scripts. So if you can perform a task in Fireworks, there's a chance you can convert it into a script from there. Once it's a script, it can be integrated into a batch process. That said, not all actions performed in Fireworks can be recorded properly, so extra work is often required to make a script actually useful and workable.

    Congratulations on finding a solution, and thanks for sharing!

     

    I had no idea you were working with so many images. Using Photoshop's Replace Color adjustment was a great idea.
