Method and calculation
Reduce resolution within a chosen rectangle while retaining the surrounding pixels.
Inputs and settings
Pixelate Image Region accepts Left (%) (minimum 0, maximum 100); Top (%) (minimum 0, maximum 100); Width (%) (minimum 0, maximum 100); Height (%) (minimum 0, maximum 100); Pixel block size (minimum 2, maximum 100).
Worked example
Pixelate Image Region example — Left (%): 25; Top (%): 25; Width (%): 50; Height (%): 25; Pixel block size: 12. Preview instructions: Select a still photo, then use Left (%): 25; Top (%): 25; Width (%): 50; Height (%): 25; Pixel block size: 12. The result is a PNG with reduce resolution within a chosen rectangle while retaining the surrounding pixels.
Output and limitations
The chosen patch is reduced to a small intermediate grid and enlarged without smoothing. A larger block parameter creates fewer coarse cells. Block averages can preserve recognizable patterns; select the solid redaction tool when the original information must be removed.
