Dear Loïc, I have the same issue. The scanner we use is capable of high speed scanning, but when using color mode with 200 or 300 DPI the scanning speed radically decreases. I have tried using the above mentioned methods: TwainAcquireToFile, TwainAcquireToMemoryFile, TwainSetAutoScan(true), no filte...

Our client scans couple hundred pages at once and this issue can be replicated with 200 DPI at 200-300 pages too. Keeping this amount of file in memory causes errors, saving to pdf then merging together 200 pages seems more time consuming, but I gonna give it a try. If you have further suggestions p...

The reading of the BigTIFF file format wouldn't be a problem, because as I mentioned in my first post I'm saving the TIFF to the drive only for creating PDF files. The TIFF file is only opened with GDPicture then deleted. Is there a way to split the TIFF file i...

You have to select the sample.tif and a destination folder in the application and hit Start to reproduce the e...

The sourcecode: SetActualImage(0); int mpt = imaging.CreateClonedGdPictureImage(actualImage.handle); GdPictureStatus gdst = imaging.TiffSaveAsMultiPageFile(mpt, filename, TiffCompression.TiffCompressionNONE); for (int i = 1; i < imagesInTifFiles.Count; i++) { SetActualImage(i); gdst = imaging.TiffAd...

Hi, I'm using GDPicture for scanning images and saving them in PDF. When using TiffAddToMultiPageFile in iteration at the 46th call I get a GenericError and in the resulted PDF this page will be black or faulty as seen in the attachments. There are two ways of reproducing this error: Iteration with ...
