Issue
When I load a B&W (1 bit) TIFF using the loadContent command, I receive the following error:
[ERROR] Could not open 'file:///C:/test_jp/single-ps7.TIF' because the TIFF file bit depth is not supported. Only 16 or 8 bits per sample is supported..
Applies to
Adobe Graphics Server
Adobe Document Server
Solution
There are many different TIFF formats and Adobe Server doesn't support all of the TIFF formats supported by Photoshop. A workaround would be to open the file in Photoshop and save as another type of TIFF or as a PSD.
AGS does not support:
- Saving compressed TIFFs
- B&W (1 bit) TIFFs (there are many variations of these)
- multi-page TIFF files
- TIFFs with transparency
- Planar TIFFs
- TIFFs with ZIP compression
- Adobe Server doesn't full support layered TIFFs
It can load a layered TIFF without transparency created in Photoshop but the output has only one merged layer with a white background.
- CMYK TIFFs that have more than 4 channels
Could not open 'some.tif' because the TIFF file number of channels is not supported. Only 4 channels are supported for CMYK files.
This error is usually triggered by alpha channels. Saving an image from Photoshop with the "Save Transparency" option selected will generate this error.
