GdPicture Imaging

Hello Loic,

Version: Gd Picture Pro Activex Imaging toolkit version 5.12.8

We are facing an issue with opening tiff images compressed with JPEG compression [JPEG-In-TIFF]. The tiff images were able to be opened in MS Office Picture manager but not in the Windows Picture & Fax Viewer and Gdviewer.

Also, I came across a thread in this forum which informed me that

Code: Select all

TiffCompressionOJPEG

option is available for decoding JPEG-In-TIFF image formats. But my SaveAsTIFF function do not show this option in the drop-down list.

Please assist me at the earliest with a sample code, with decoding the tiff images so that the images are to be opened in the gdviewer.

Please find below the attributes of the tiff image that we are facing issue with:

SubFileType (1 Long): Zero
ImageWidth (1 Short): 1269
ImageLength (1 Short): 1648
BitsPerSample (1 Short): 8
Compression (1 Short): JPEG Original TIFF 6.0 spec
Photometric (1 Short): MinIsBlack

A solution to open this image in the Gd viewer would be highly helpful.

Please find the attachment which shows that TiffCompressionOJPEG option is not available.

Hi,

OJPEG compression is 100% supported for decoding purpose.
I think the problem is away.

Please attach the image you are trying to open for investigation.

With best regards,

I can provide a sample TIFF - other tiff utilities show its compression type as 6 (Old JPEG in TIFF?). This can be opened in Microsoft Document Imaging, Kodak, Kofax but not in GD PIC PRO 5.12.8 (ActiveX version) or Fax and Image viewer.
