Reading psd layers from file performance problem

[kFk]

I'm reading layers from psd like this:

Code: Select all

Image im1("c:/test.psd[1]");
Image im2("c:/test.psd[2]");
Image im3("c:/test.psd[3]");
..

The psd file is large (ca 70Mb and 500 layers) and if I understand correctly ImageMagick reads whole file each time on each layer load.
Is it possible to speed up this process somehow?
Thanks in advance!
