Is the header burned into the image, so you need to do OCR on it, or is it metadata stored in the header of the image file?
hi and thanks for help,sorry for the late answer.
I upload one image to see it your self.Yes the header is in the image,i just want to export it to a new image that has only the header.Furthermore i want to export the date and the page number.Hope the image helps you,so you can help me!!

Extract the text. Hopefully all the images are aligned and you can just crop the image. Then do OCR on it.

croppedImage = originalImage(row1:row2, column1:column2);
my problem is i have a lot of pictures to do that task and must be general,not only for that picture.So i'm asking how i put the correct number of row and column so that be good for other pictures?
