Magick.net : how to improve speed when load 1 bit tiff file

[hsilviu]

Hi,

I am using C# 2019 and Magick.NET-Q8-AnyCPU version 11.2.0.0 for loading 1bit tif files.
Everything works great but a bit slow with the way I am using it:

MagickImage mImg = new MagickImage(img.path); // takes about 22 seconds
mImg ?.Scale(745, 0); // takes about 17 seconds

The image is 74500x60500 with 2540 dpi (it is not my file and I can not request a different one) :

Is there any way to get a better time for processing?

Best regards,
Silviu

Those are images with huge dimensions. There is not much that you can do about it. They take a long time to process.

I know there are huge I just hoped for a way to save some time.
Thanks for your answer!
