Setting New Image Size
Surprised I could not turn this up in the Search. Whenever I open a new image to resize it, it does not change size, but sometimes I have seen it larger than this standard size. I need more space for my work, I dont like working with Zoom, or small print. How can I fix setting new image size so the entire background will increase?

RE: Setting New Image Size
If you want to chnag the size in pixels of an image, use "Image/Scale image". But keep in mind that the size in pixels cannot be changed lightly. When you reduce that size, it's final. You willl never go back to the original image by increasing the size. You will only get a blurry image.

If you want to add more space on the sides for additional content, use "Image/Canvas size". The layers sizes (which is what really matters) will remain unchanged.

Planning an adequate image size from the start is fundamental when working with bitmap images.

This is what I mean, the background.

If I set it at 600x400, 800x600, or 1024x768 pixels, the background is always physically the same size. It is only different if I save it as these sizes and then they are bigger or smaller in my folder. Then the end result where ever I share the image is at the size I saved it as "new image".

This is why I ask why it happens when setting new image size? Because I need more physical room while I work. I think there have been times they change, maybe not, if not then maybe mine is defective. Should I reinstall? Thank you.

RE: Setting New Image Size
I have a hard time understanding what you call "physical room" in an environement where everything quite virtual...

When you create an image from scratch, you can give a canvas size, which will be the size of the image when you save it (say, 800x600). You can create/work on a bigger image (say, 1600x1200) and scale it down when you "export"(*) it for use (to 800x600, for instance). but if you work from existing images, your size options may be more limited.

Of course, a smaller size in pixels produces a smaller size for the file, but disk space isn't really an issue these days.

(*) The recommanded workflow is to save the image as XCF. This is the file format that saves everything (layers, masks, selections, channels, paths...). Saving in any other format is "destructive", because you lose something that could be useful if you need to rework the image later. When you want the image in another format just use "save as...". Coming versions of Gimp will always save as XCF, and there will be an "export" menu item to save in varoius formats.

RE: Setting New Image Size
OK, thanks for your responses, I do appreciate them.

What I mean is

1.) I click: File > New
2.) I have several options (i.e. 600x400, 800x600, 1024x768 pixels etc)
3.) I choose 600x400 pixels and I get about a 5 inch by 8 inch space of white screen to work with.
4.) If I choose 800x400 pixels I get about a 5 inch by 8 inch white space to work with.
5.) If I choose 1024x768 pixels, I get about a 5 inch by 8 inch white space to work with.

I would like to have more white space to work with, but any option I choose, I get the same size of "physical" room, or work space (default white background).

RE: Setting New Image Size
It changes if I set the new image with inches-- rather than "pixels". The white background enlarges.

RE: Setting New Image Size
Perhaps, but what is important is the actual pixels. Everything else is secondary.

RE: Setting New Image Size
**UPDATE** Sigh.. once again, right after posting I found the answer to my question. Mid-bottom right of the white background> there is 50% to 100% and then even higher. So thats what I have been looking for since the start of this thread. I actually learned that right in the beginning of using Gimp. Well, now everyone knows!

Alright heres the deal. I really need a large picture. I know Gimp 'automatically' resizes a new image so it fits into a space. But really I want to work on a large Image and Gimp just isnt giving me enough room to work with.

Here is on a 19" monitor and these are the dimensions I am using, and this is how much white space Gimp is giving me to work with. (The same goes for Pixels, this is in inches):

This doesnt happen on your Gimp?

You are talking about the zoom display/control widget in the status bar? I thought you didn't want to work with zoom... or were you talking about some general desktop zoom tool?

RE: Setting New Image Size
I want to make an image that is the physical same size as my monitor. Everytime I set a "new image size", it was opening as a small white background size, and I couldn't work with that because the actual image was going to have to be as big as my desktop space. So I kept trying to make the image bigger and bigger! Only to have the same size white background opening up. If I make it the right size and set it to 100% (because Gimp will automatically resize anything over a certain amount of pixels), then I can work on a large white background.

An image in Gimp has no physical size. It has pixels. If you want an image as big as your desktop (wallpaper?), give it the right size in pixels.
