jagged transitions in actual pixels

The code below displays images in actual pixel dimensions.
Actual size (call method “size” …) work perfect with nice smooth transitions between the display of the images no matter what size they are. However, in ‘actual pixels’, if there is a significant difference with the previous image, this mode works jagged with ugly transitions, specially with large images.

Is there a way to display images in actual pixel dimensions with a more smooth transition from one image to another?

	if scaled = "ap" then --> actual pixels
		set title of window "show" to "Actual pixels"
		set image scaling of image view "image" of window "show" to scale to fit
		try
			tell application "Image Events"
				launch
				set theImage to open file currentPath
				set dim to dimensions of theImage
				close theImage
			end tell
			set widthxx to (item 1 of dim) div 1
			set heightxx to (item 2 of dim) div 1
			set size of window "show" to {widthxx, heightxx}
			set size of image view "image" of window "show" to {widthxx, heightxx}
		end try
		return
	end if
