Hello.

Is it possible to create a batch process to add a custom background to multiple pngs?

Thanks!!

Is it possible to create a batch process to add a custom background to multiple pngs?

I think not: it would be possible if the Batch convert 'Watermark' function had an option to use loaded input files as the 'watermark' on a selected fixed background, rather than applying a fixed watermark to all loaded input files.

This situation arises occasionally, and I think the possibility of including such an option was discussed once, so if it might be worth making a suggestion to add one. Edit: I have made a suggestion: Batch convert 'Watermark option' - Add option to apply loaded images to a fixed background.

This should, however, be possible using an NConvert script that applies each loaded input file as a 'watermark' to a fixed custom background.

@JuanMi73: See my edit above, I have made the suggestion.

Edit: I have been able to do it with nconvert and batch file.
