Error message "Alpha channel is not supported in TIFF files"

  • When adding items you are prompted with a message that TIFF files are unable to process because "Alpha channel is not supported in TIFF files"
Applies to
  • CONTENTdm 
  • Project Client

CONTENTdm Project Client is unable to support TIFF files with an Alpha channel. A solution to this would be to use an image editor to remove that Alpha Channel. If this is happening on a large number of objects then you should review the file creation process and scanner settings. For additional assistance, contact OCLC Support and provide an example file.
