How to use a pyvips in python to generate tiff format from mrxs #498

Open Fighting-bruceCHN opened 2 weeks ago

Fighting-bruceCHN commented 2 weeks ago

Hi, i want to ask if there is a method in pyvips that i can use to transfer a wsi image in mrxs format to the tiff format

Thank you su much for the help

Hello @Fighting-bruceCHN,

Yes, they work like any other image format, so maybe:

image = pyvips.Image.new_from_file("xxxx.mrxs")
image.write_to_file("yyyy.tif")

You'll probably want a certain type of tiff, perhaps:

image.write_to_file("yyyy.tif", compression="jpeg", tile=True, pyramid=True)

Thank you for your help, I have tried your code, does the result it produced a multi level tif or does it only contain certain level, my original mrxs cotains 9 levels, how can i edit the code so that it create a certain level tiles.? And also when i use image.write_to_file("yyyy.tif"), it produce a tif. file in size 65.3 GB. image.write_to_file("yyyy.tif", compression="jpeg", tile=True, pyramid=True) produce a file in 1.03gb

By default, libvips will open the highest resolution level. You can select a level from the MRXS file with the level= option, perhaps:

image = pyvips.Image.new_from_file("xxxx.mrxs")

When saving a TIFF, by default libvips will write a single uncompressed striped image. You can write other types of TIFF with the various save options.

MRXS files always contain the entire slide area, even if the specimen is much smaller, so there is a lot of wasted space. You can use the autocrop option to only load the specimen area.

I suggest:

image = pyvips.Image.new_from_file("xxxx.mrxs", autocrop=True)
image.write_to_file("yyyy.tif", compression="jpeg", Q=85, tile=True, pyramid=True)

The documentation has all the details:

The vipsheader program can be useful. For example:

$ vipsheader -a CMU-3.mrxs
CMU-3.mrxs: 109240x220696 uchar, 4 bands, srgb, openslideload
