I received an image with colored lines that I need to include in a report. However, the image will be scaled down and the lines will be thin making it hard to see what color they are (especially in print).
This is a sample of the image. It doesn't make sense on its own, but it's just to show what my source image is.
Can I somehow increase the thickness of these lines? Somehow make them bleed to the surrounding area in their original colour? The latter aspect is important so a glow (of one colour) is not going to cut it.
If other software is more suitable to do this, please do share. Photoshop was just my first idea.
