Inpainting of text with transparent background

[xulihang]

OpenCV's inpainting cannot handle transparency. So ImageTrans will convert the color space from BGRA to BGR for inpainting. This works well for text with a colored background. But if the text has a transparent background, it does not work.

Possible solution:

If the percent of pixels with a 0 alpha value of a text area is over 25%, then set the part of the image corresponding to the text mask to transparent.

In v2.9.1, I added a transparent text mode to precisely remove the text.

It will remove text based on the text mask and near pixels' values.

It is recommended to check the process by text areas checkbox.
