I have a basic logo that I would like to see with various sized pixels. I tried just shrinking the image and then zooming in but the reduction created reduced opacity pixels along the edges. I would like all the pixels to be solid.

Failed experiment

  • Sorry, to be more clear: I WANT this to be pixelated. We want to make a representation of this logo using post-it notes. :-) – Tony Smith Apr 1 '15 at 16:14
  • Turn off anti-aliasing in your resizing tools. – DA01 Apr 1 '15 at 17:07
  • Its also posible to delete the alpha by duplicating the individual channel colors without resorting to a limitted palette. – joojaa Apr 1 '15 at 20:31

The easiest way is to change the image to Indexed Color instead of RGB via Image > Mode. All transparent pixels will be removed and none will be created when the image is downsized.

Alternatively, you can duplicate and merge the downsized layer repeatedly. Even a pixel with 1/256th opacity will be opaque after 8 iterations.

Unless your shape only contains 90º angles, it will have semi-transparent edges. The reason is that pixels are square, so Photoshop tries to compensate for half-pixels with transparency. I made a little diagram to show what I mean by half-pixels:

Half-pixels

  • @Tony Smith - thanks for clarifying that you want to make this with post-its, awesome idea. My recommendation would be using the original pixelated image you posted, and only use a post-it for a square that is 100% opaque. That should still give the same illusion from across the room. – Suki Apr 1 '15 at 16:20

The answer seems to easy too me so I guess I did not understood it well :)

But did you try: Filter > Pixel > Mosaic?
