This question is asking for an ImageMagick method not Photoshop.
I'm hoping someone will be able to tell me what to type in cmd to perform the following operation:
I have an image file with a black/grey background. There is bold blue text on top of that background. So basically, I'm looking to convert anything that isn't part of the text (i.e the backround) to transparent in the PNG. Here is my image:
I would also like to do this with an identical image where the text is coloured red. The point is so I will end up with images that only contain the text against a transparent background, so that I can place them on new background. I have tried
convert image.png -transparent black newImage.png in the ImageMagick cmd tool, but to no avail. I think if I new how to specify the range of black and grey rather than just 'black', I might have better luck, but the command line tool is overwhelming as I'm not a graphics person. No clue what I'm doing...
