Segovia via Tiff Sent: reede, 9. detsember 2022 03:29 To: [email protected] Subject: [Tiff] How to write multi-file TIFFs Hi all, I'm writing to ask about how to create a TIFF with multiple sub-images. Our writing code at Krita is unable to create this kind of files, creation fails with these lines logged: > krita.file: "TIFFLinkDirectory: Error fetching directory count" > krita.file: "TIFFRewriteDirectory: Error fetching directory count" A breakpoint on the TIFF error writing routine shows that both are issued the moment I call TIFFWriteDirectory for the second and further layers. TIFFCreateDirectory, which I saw suggested in tif_overview.c, does not have an effect here. Does anyone know the correct incantations to create this kind of files? I'm running LibTiff 4.4.0 at present.
