Hi @charlesw , we need the function load LoadMultiPageTiffFromMemory. Is this pull request ready to be merged? |
|
The pull request looks fine. Unfortunately ran out of time tonight (just
trying to update dev branch to 5.2 then I'll merge this change in).

Are there any advantages to throwing in a multi-page image? Following the responsibilities, I would have expected an OCR module to focus on OCR. Consequently, there would only be flat interfaces for simple sources, like 1-page objects. In my opinion, the preparation of a multi-page image (splitting?) does not belong there. |

Using leptonica to read images directly can have significant performance advantages.

is not enough. Basically a multi-page processed as a block takes longer than when its individual pages are processed in parallel. This means that it would have to be investigated how leptonica processes. And all just to save yourself a split ? |
