Pictview - preload next image
Posted: 17 May 2011, 23:41
A popular feature in other image viewers is that of preloading the subsequent image.
Since the normal usage pattern is load image / stare at image for a few seconds / press key to load next image - it is a significant speedup (at the cost of RAM) to be loading and processing the next image while the user is looking at the current image - then when the user presses a key, page-flip, unload the previous image, and start loading the following one.
Some viewers keep more than one ahead in RAM - or predict and load in the other direction if the user starts flipping backwards. Even without those though, any version of preload would be a great timesaver. When I'm doing photography I often have to review thousands of images...
