I had to print a few images a yesterday and noticed how slowly the Print Preview dialog works. An user has requested that the dialog needs to be disabled. I suppose it needs an improvement to how the picture is handled. It would not help in that other user's case, but it will make setting up the print job faster in general.
My pics were 75 megs, grayscale (loaded from a deflated PNG, but I think it doesn't matter).
It appears that currently IrfanView downsamples the input picture for the preview dialog every time a setting is changed, such as center or uncenter, adjust margins etc. It also repeats the prorcess if the preview pic needs to be redrawn, such as when the user moves a window over the small pic. What if the program downsampled the picture once to an acceptable size for preview purposes, such as < 400*400 px² and then worked with that smaller image?
I'm not sure if it makes sense what I'm saying. If it does, then please move to the feature section.
