goddi Posted January 18, 2023 Report Share Posted January 18, 2023 Greetings, I was helping a friend with his PTE project. He was using V10. He had some Tiff images and they loaded correctly. However, he then upgraded to 11.0 Pro. But the Tiff images would not load. Is this a bug? When I converted them to jpgs, they did load correctly. Gary PS I just noticed that the file extension is 'tif', not 'tiff'. Wonder if that is the problem. But they loaded in the V10. ===================================== Quote Link to comment Share on other sites More sharing options...
Igor Posted January 18, 2023 Report Share Posted January 18, 2023 Hi Gary, Can you send me one sample TIFF file? 2. Windows or Mac version? Quote Link to comment Share on other sites More sharing options...

Greetings Igor, I've attached one of the TIF files. He is using Windows. I tried it in my Windows10, and it fails to load in my PTE V11, too.

Paul L Posted January 18, 2023 Report Share Posted January 18, 2023 Same load error here on Win 11. Quote Link to comment Share on other sites More sharing options...
davegee Posted January 18, 2023 Report Share Posted January 18, 2023 I am not sure what the problem is but a simple Open in Photoshop and Save As xxx.tif makes it load ok in pte v11. DG Quote Link to comment Share on other sites More sharing options...
jt49 Posted January 18, 2023 Report Share Posted January 18, 2023 As PTE 10, and lots of other programs (IrfanView, XnView, LibreOffice, Photshop, and many more) can show this image, the situation should be clarified Quote Link to comment Share on other sites More sharing options...

DG Greetings, The question is that the file worked in V10, but not in V11. I did open it in PS and saved it as a jpg and it worked. So, why would this tif work in V10 but not V11. The person I am helping is a newbee so I don't think he or others would have figure it out since it had worked in his earlier version. Looking at them in MediaInfo, they look the same. And it works in other photo programs. So it is a curiousity that I I hope Igor can explain. Thanks... Gary Quote Link to comment Share on other sites More sharing options...
Igor Posted January 19, 2023 Report Share Posted January 19, 2023 Gary, thanks for the sample TIFF file. I see this problem. In V11 we updated video/graphics encoders/decoders for TIFF. And it seems that the problem occured with certain TIFF images. TIFF container offers several options for a compression (JPEG, LZW, ZIP, etc).

Igor Posted January 19, 2023 Report Share Posted January 19, 2023 Honestly, I cannot understand why this TIFF file cannot be loaded in V11. In Photoshop I've saved a series of TIFF images with different options: no compression, ZIP compression, LZW compression (with one layer, or several layers), IBM format or Macintosh format. All created TIFF images were shown correctly in PTE 11. The only known issue with TIFF with JPEG compression - this format is not supported in V10 or V11.

goddi Posted January 19, 2023 Author Report Share Posted January 19, 2023 Thanks, Igor. I checked with my friend to see if he remembered how he created the image. All he can remember is that he must have scanned a print with a flatbed, but does not remember exactly how or with what. At least now we know what to do if this issue reoccurs. What is strange is that the MediaInfo does not show any difference between the original and being re-saved in PS. Thanks... Gary Quote Link to comment Share on other sites More sharing options...
denisb Posted January 19, 2023 Report Share Posted January 19, 2023 Hi, https://www.pteavstudio.com/forums/topic/35233-tiff-images-not-being-loaded-v110-pro/?do=findComment&comment=171129 Igor the default tiff from The Gimp is MIME Type : image/x-tiff-big They call it "BigTIFF variant file format" And Pte cannot load this tiff (But this not the case here) Denis Quote Link to comment Share on other sites More sharing options...
tom95521 Posted January 19, 2023 Report Share Posted January 19, 2023 I think maybe PTE does not like JPEG TIFFs. If I save in Irfanview with JPEG compression of TIFF then I see a black image. I see Igor already mentioned this. I don't know what other reason could cause this problem. Tom Quote Link to comment Share on other sites More sharing options...

Tom, TIFFs with a JPEG compression also didn't work in previous v10.5, too. Current code doesn't support this format. Quote Link to comment Share on other sites More sharing options...

Igor Posted January 20, 2023 Report Share Posted January 20, 2023 Denis, you're right. I checked saving of TIFF images in GIMP. The problem with BigTIFF files in PTE 11. BigTIFF is an unofficial extension of TIFF format which introduced 64-bit offsets to be able save images larger than 4GB. We use FFmpeg library 4.4 to decode TIFF images and this version doesn't support BigTIFF format. Earlier we used FFmpeg 4.1.1. For some reason they dropped support of BigTIFF format. We need to think how to solve this issue. Quote Link to comment Share on other sites More sharing options...
tom95521 Posted January 20, 2023 Report Share Posted January 20, 2023 I notice if I use MacOS Preview to export image as none compression TIFF it does not work in PTE 11 but it does work in PTE 10.5.9. Tom Quote Link to comment Share on other sites More sharing options...
denisb Posted January 20, 2023 Report Share Posted January 20, 2023 Igor, it's not important as you can untick "BigTIFF variant file format" in GIMP Denis Quote Link to comment Share on other sites More sharing options...
