Hi, Ron!

I need (1), i.e extract an image which is the same size as the text area.
I will use a dedicated tool for OCR (2), which is the next step.

Basically this must be a primitive implementation of layout analysis. =)

And the image is here (I thought it'll make it attached):

Note: the red area is not really important.

Alex

PS: I've posted the same question here:

Do you mean

(1) extract an image which is the same size as the text area, or
(2) extract the text letter-by-letter

The latter is called Optical Character Recognition, and I do not know of
any such feature within IM.

No image attached. Please upload to your web site.

Sure.

Sounds reasonable, but also sounds like (1) above.
