I tried to crop 433 MB (half gigabyte) image via the custom selection command. Selection was created but when I executed the crop command nothing happened: Irfan was busy about a second and that's all. My guess is that it could not allocate memory but it DID NOT SAY anything.
In fact there was enough memory for about 3 such images. After the unsuccessful crop, my system information tool showed that Irfan had allocated 892,664 kB – twice as needed for display. Is not correct that in theory cropping could require at most twice the memory needed to display the image? You just copy pixels from one location to another and after the process is complete you discard the source data.
