Hello!

May I see a stacktrace please.

If you can share a sample tiff file to reproduce the issue we can probably support this.

[i2534]

this file, can cause tiff: unsupported feature: compression value 2
then patched, it can cuase ccitt: missing End-of-Line(this problem is x/image's...)

confirming missing ximage/ccitt support for tiff compression type CCITT Group 3 1-D
