In our Application we convert the pdf in Tiff and save it.
In our tests we monitored followed issue:
If the pdf has more then 1000 Pages, the pdfConverter.SaveAsTIFF(filepath, tiffSettings) method occurs following exception. up to 1000 pages is everything ok and works fine.
System.Runtime.InteropServices.ExternalException (0x80004005): A generic error occurred in GDI+. at System.Drawing.Image.SaveAdd(Image image, EncoderParameters encoderParams) at #=z9q8xEPHRKjXP2gWUkdFasqh9lD6h9juyDlRWpOQmo3j_fSpNKA==.#=zK6vdKsI=(Bitmap #=zGIg6ARU=) at Aspose.Pdf.Devices.TiffDevice.Process(Document document, Int32 fromPage, Int32 toPage, Stream output)
Have you any idea?
if you want, we can deliver a sample application

Hi Asad
This issue is not a low prio issue, we can not convert pdf that has more then 1000 pages, now this ticket is open since 10 Months. Please set the prio of this ticket higher
Please note that the issues in free/normal support model are logged and investigated on first come first serve basis and they posses normal priority level. We offer paid/priority support option as well where you can report an issue that needs to be resolved on urgent basis and such issues posses the highest priority level. Nevertheless, we have recorded your concerns and escalated the issue to the next level of the priority. We will surely inform you as soon as we have some news about its resolution. Please spare us some time.
System.Drawing, Filesystem, Streams have many limitations. You are not using compression and you want to get a very large TIFF file with a resolution of 1984 x 2806 and 1089 pages, the file images size would be 24,250,305,024 bytes = 22.58 GB.
You can enable compression:
var tiffSettings = new TiffSettings { Compression = CompressionType.LZW };
An exception should not occur, and the file will be about 0.046 GB, which is 490 times less.
Please check our last response in this thread and use suggested option to prevent the issue. Please share your sample files and code snippet in case you still face any issues.
