I have been looking at it. I am actually using (a similar) approach to read embedded bar-codes, but there I can test all images. The best I can see in ExtractImages is a way to check if there is only one image. However I can not check if there is additional text or other content, so that I do not mistakenly skip a page that has a single logo (for instance) and lots of other text information. I tried looking at PDFTextStripper, but that is hard to follow.
Is there any sure(-ish) sign that there is text on a page that I can use? Can I check for the existence of something that would tell me that there is additional content on the page other than the single image? 2017-10-30 15:53 GMT+02:00 Tilman Hausherr <[email protected]>: > Am 30.10.2017 um 14:04 schrieb Lachezar Dobrev: >> >> I have to process PDF files, that (supposedly) contain one big image >> per page, which is a result from a Document-Scanner.
