Re: annotate with inverted text colors?

Good point. Perhaps a shadow under that annotation?

Re: annotate with inverted text colors?

Thanks. Would there be any sane way to do this with annotate or something similarly simple? The text is just pixel text.

annotate with inverted text colors?

I would like to put a small watermark on images.

I would like the color of the text to be an inversion of the colors below it, on a pixel by pixel level, thereby insuring it showed up on everything.

Is this possible?

fade image to transparency?

I have a jpg with an arbitrary size.

using the commandline, I'd like to:

1. Crop the image at 100px height
2. Fade the last 30% of the image into transparency
3. Save as png

I've been reading the documentation for hours, but I can't figure this out for the life of me. How can I do this?
