Digital Light & Color

A couple of Questions, 1. Often to almost always, when a Preview Window opens to show a view of a particular action, it appears very grainy. I set my previews to Medium Size. It becomes difficult to evaluate Sharpen and other transformations as a result. 2. Sometimes only after three or transformation actions, I get a MEMORY FULL splash screen, and cannot continue with my edit... I then close out of PWP, return and all is well again and can continue with the edits. I am careful to only have the image file that I am working to be the active one, all other image files are closed.
I am using latest upgrade to PWP Pro 3.5
Thanks,
Gary

The previews are low resolution images (for speed). Changing to Large Size doesn't change this. To evaluate (many) transformations you will need to set your preview window to 1:1 and scroll to a suitable region.

The apparent graininess is due to the fact that image windows are anti-aliased and preview windows are not. To anti-alias preview windows would slow down previews considerably, effectively defeating the purpose of preview. If you preview at a zoom factor of 1:1 or greater anti-aliasing is not an issue and this is what you need to do to preview sharpening, etc.

If you are running out of memory, first make sure you have a swap file of 4GB which is the maximum useful size under 32-bit Windows. If you are still getting out of memory errors, you are probably working with very large images. An upcoming version of PWP will support 64-bit Windows and remove many of the memory limits in the 32-bit version.
