If I place a png file that has intentional transparent space surrounding the image into a photoshop document photoshop seems to remove that surrounding space. This wouldn't bother me too much, except that what tends to happen is that if I resize the placed png after it has been placed I end up with hard edges where photoshop has not antialiased beyond the edge of the now cropped image, resulting in an ugly hard edge.
I end up having to work around this by, for example, adding an almost totally transparent pixel beyond the visible edge of the image I'm placing, within the source document, to force photoshop not to crop to the visible pixels, and thus include the antialiasing on the edge as it does everywhere else (to make the resized image look nice). This creates new problems though, such as causing photoshop to include that almost invisible pixel when applying effects such as glow/shadow etc.
Is there a way to prevent this phenomenon when placing PNG files?
Edit: Source PNG added by request (however it was created purely to illustrate my point. This happens with any placed image with transparency)
