As part of the production process some text appears in 2 of the colours only (black and blue). So I would like to:
- Separate each colour into its own graphic (layer?)
- OCR the text in each of these two layers.
- Replace the text with a newer font with the same text in - in these layers.
- Recombine the layers into a composite graphic.
The output could be bit mapped (PNG?) or vector (eg SVG) as downstream processing can handle either. (In the SVG case, md2pptx uses CairoSVG to turn a SVG into a PNG under the covers.)
Any thoughts on how to accomplish some of the above? I put it under “Mac” because that’s where I expect to be building this.
