Hi all,

I just want to decrease the resolution of my image. The problem is that every time I try it also affects the image's size.
I go to the Image menu, then Scale image.

Thanks guys,

DPC

Would Filters>>Blur>>Pixelise do what you want:

[attachment=436]

I wonder if it is this?

[attachment=437]
Left Image 
200x200 pix resolution 96 ppi Print size is 53 x 53 mm

Right Image
If the resolution is doubled to 192 ppi then to maintain the print size 53 x 53 mm the image size also has to be doubled to 400x400 pix

That is the way raster (bitmapped) images work.
