As a developer, I would like to save TIFF documents using Group 4 compression

A customer is interested in using PrizmDoc's Content Conversion Services feature to create TIFF files that use G4 compression.. Currently, CCS only creates TIFF files with LZW compression.

Having this ability will help optimize file sizes for black and white images.

Thank you.

    The work on this feature has been completed and will be available in PrizmDoc 13.13, Beta 2 on May 27, 2020 (tomorrow). If you want access to the beta version that includes this feature, please contact Accusoft Support on or after May 27th.

    The feature will be in PrizmDoc 13.13 final release which will be available on June 23, 2020.

    Hi Keith,

    It's looking like a mid-June timeframe for the 8-bit LZW and support for Group 4 compression in TIFF. That would be the soonest based on our schedule. I'll let you know if that changes.

    Hi Mark, just a quick follow up -- does the 8-bit color LZW feature plan to be made available by end of march/april?

    Not a problem! I'll created another feature request to address 8 bit color LZW and attach your info to that one since its a different need than this feature.

    Hi Mark, we would only need 8 bit color LZW.  Sorry for the confusion!

    Hi Keith,

    We can reduce bit depth. We would need to get a bit more detail. For example are you talking about reducing to 8bit grayscale or color. Is it only to 8bit or is 1bit needed as well? We can do all that, the question is just how much do we need to expose via the CCS API. Also, does this mean you don’t need to change the compression at this point?

    Let me investigate and I'll get back to you.

    I just reached out to another team to clarify and found out that they are using 8 bit depth with LZW.  Apologizes for the confusion about Group 4 compression, but it sounds like LZW is what we need, however the output tiff from prizmdoc is 24 bit depth.  Is there a way to specify a lower bit depth in the conversion api?

    Thanks Mark!

    I needed to confirm G4 compression was the only type needed. The team will need to review and I'll get back to you. The gating factor of how long is dependent on when we can fit it into the development schedule.

    Hi Mark,

    We would really appreciate that! Our major business cases are outputting to tiff or pdf.  Pdf file sizes looked great.  What is the usual turnaround time for a feature request like this?  The reason I ask is because we might not have enough time to wait as this project has a release date of march/april.

    Hi Keith,

    We can add Group 4 compression to the PrizmDoc Content Conversion Service. Are there other types of compression we should support (like JPEG for example)? If we add a new compression type, adding others at the same time would be more efficient.

    Our organization has a business case for converting images taken by phone into tiff format.  Due to how bloated the files are via LZW compression we will need to change the compression type or compress the files ourselves which is disappointing that PrizmDoc doesn't handle it.
