Hello! I am OCR-ing large amounts of images of historical texts scanned on a black backround. When using the "Deskew" preprocessing option, the triangles that form around the deskewed image are alwas light grey or white, and I cannot find an option to change the color of these triangles to black. Here is a sample deskewed image:
The "Deskew" option is very useful in general, because it is very good at straightening the text lines, but it becomes useless in my case because of the light triangles that form around the image. Is there any way to mitigate this issue? I am using FineReader 14 on Windows. Is this issue addressed in newer versions of FineReader?

Hi Ivan! In FineReader 14 (as well as in the newer versions) you can use Crop tool in the Image Editor to get rid of these light triangles before saving the recognized document. Hope it helps.
Best regards,
Yuriy
Thank you for your answer, Yuriy!
I should have mentioned that I am using Hot Folder to batch OCR multiple images at the same time. Is there a way to use the Crop tool (as a processing step) in Hot Folder?
Unfortunately, Crop is a manual-operated tool only. But you can modify your Hot Folder task to save the results of processing to an internal FineReader Document format. After processing is completed by Hot Folder, you can open this FineReader Document in the OCR Editor, all recognized texts will be there, ready to export or saving. To get rid of the triangles, apply Crop before saving or sending the document to the format of your choice (suppose it's most probably PDF).
Good idea. Thank you!
