Re: [Gimp-user] Resolution

[Barry Say <barry12 nspipes co uk>]

A small clarification.

I do a lot of stuff with A5 pages. At 100 dpi an A5 image will turn out at at about 825 x 1175 pixels. I find this gives sufficient resolution for most purposes, looks good when displayed at native size on the screen, and is the appropriate size to store as a page in an .odt document which can then be transformed to a .pdf which is reasonably economic in size. Thus a single image file can serve many purposes and if I wish to refine the post processing to improve quality or reduce storage  overheads then I only have one file to worry about thus making maintenance more straightforward.

Yes, I was a bit wooly in my description, but I think the method works.

Hi Leon,

1. If you select Image > Scale Image, The Scale image box opens.
2, Change the Image Size units to something convenient.
3. Note the width.
4. Change the resolution to what you require.
5. Change the width back to the original size, the height will follow.
6. Select Scale Image

The size of the image will remain the same in cm but its size in pixels will change.  I often do this to publish scans on the internet.
I regularly scan stuff at 300 dpi and preserve this as a record, but I will generally reduce the resolution to 100dpi fore web publishing to save on bandwidth.

Is there a way to change the resolution of a picture without it changing the size.

 

I cannot find a way to separate the two..

 

Thanks...Leon
