I have a web page with text. Could you show me how to modify a screen shot so that the clipboard contents contain a transparent background (BG). Then I would like to paste only the text into a new page which, again has a transparent BG, or a BG with a color that I can control. Deisred end state is text with my color BG.
Then if possible I would like to transform the text color from black to a different color that I can specify. Please show me also how that can be done, if it can be done.
You can not take a screen shot with a transparent background. You'll have to take a screen shot, then open the shot and remove the background like any other image.
In 99.9% of cases you get better results by simply retying the text, or copy and pasting the text into a new web page (as text, not an image). Screen shots of text for the web are not really a good method or working.
