Bioformats saving with compression is too slow



I’m also posting here as the bio-formats forum seems down.

Any format I want to use using BioFormats Export takes ages

Example: The 33MB Mitosis stack takes oaver 15 minutes to resave as a compressed tiff (JPEG2000). I’ve tried other formats and it’s the same, about one slice per second…

I’m experiencing this under Win10 and Java 8…

Anyone got any thoughts on this?




Nothing constructive to contribute beyond the fact that I have been using BioFormats from Apple OS-X an Java 8 and also experienced saving files with compression can significantly increase the time take to save.

The time seems to be consumed when saving each slice, the writeBytes() call, so at least you put in a progress bar.
