: Changing the amount of pixels in an Image in GIMP (or Photoshop) for scaling purposes I'd like to paint an image from a video game with acrylics on a large piece of mdf board. The image

@Hamaas979

In GIMP when you use Image > Scale Image, set the Interpolation method to "None" when rescaling. This will keep the hard edges of the pixels.

In Photoshop the equivalent when using Image > Image Size, is to set the method to "Nearest Neighbour (hard edges)"

If you want to paint solid pixels on the image, probably best to do it before you rescale. In GIMP and Photoshop use the Pencil Tool to paint hard edged pixels.

I notice the image you posted seems to have more pixels than you probably need. If you rescale the image using these interpolation methods, to half the width and half the height, you will get single solid pixels. This will make it much easier to paint on with the Pencil Tool.

Example in GIMP, scaled down to give single pixels, and painting solid pixels using the Pencil Tool.

If you want "bigger pixels" to make a small image bigger but still pixellated, use Image>Scale image with "Interpolation: none" in the Quality section. This gives something likes this:



If you have too many pixels, use Filters>Blur>Pixelize to replace a rectangle of pixels by a single rectangle with their average color.
