Image size
Hi all,
I need to have a pic finish at (width-3072 and height- 2048 pixels). When I click on file>new I put in those dimensions, but when I am done with pic and I export it, the picture shrinks to very small. The only way around this is to maximize the image in Gimp to 100% and use my snipping tool to outline the image, then "save as". This will save it large, but not the size I need.

My brothers and I took some pics and I added a couple things in one of mine, to try to fake them out. If the size of THAT image is way different than the rest, the fake out will not work. Am I missing something? How can I finish with the size I want. Thank you in advance, I appreciate it.

I normally use Faststone to re-size my images but it will not re-size my Gimp images.

Of course if you print it, it's a different matter. On your screen the picture at 100% zoom is displayed with the screen definition (around 100DPI) and if you export/print it it may be printed at 300DPI or 600DPI and so look 3x or 6x smaller. If you intend to print the image, make it big enough (in pixels). The "new image" dialog lets you enter an intended print definition (advanced options) and a size in physical units.

RE: Image size
I am not planning on printing it. I just want it to view on my PC. When I export, it shrinks the pic to about 6"by 4". I don't know what the problem is, it's driving me nuts though. This only happens with Gimp, if I bring in other pictures from the web, they are normal size, or at least I am able to re-size.

Other than this, I am coming along pretty good with Gimp. Thanks for you response.

RE: Image size
The 6x4 is just estimated by the way it looks. ALL other pictures from my camera OR from the web take up just about my whole 24" screen. The exported Gimp images just take up a very small area. As I said I have a work around with my snip tool, but can't get it as big as I need, but not too bad either. It's beat to do it that way!!

No I am not selecting "save for web" And I know Gimp should not be shrinking images...sounds strange, I know. It must be my computer for some reason. Thanks

RE: Image size
According to the specks it says my finished picture is 3072 x 2048, which is what I wanted. Except trust me it is not that size. As I said ALL my other ones are normal, they view large.

The image below is LITERALLLY how it shows when it is open on my computer, after I export from Gimp. That is what I should have said from the start...Thumbnail size. When I click on this posting picture, it expands some, but on my computer viewer it wont. I could try a different viewer, but if that was the problem all my pictures would be shrunk, not just Gimp photos. thanks for your help, I may just have to put up with it.

Trust me, if the Gimp says the image is 3074x2048 pix then that is the size in pixels. Viewable size can be a different matter.

This one. Same image 603x521 pix. Left hand side has print resolution set at 95 (that is my screen resolution, default is 72). Right hand side has been saved with resolution of 200.

If I open up in Gimp both will look the same, because Gimp is a raster editor and all it cares about are pixels, so it puts 1 image pixel = 1 screen pixel.

You can change this setting in the view menu, untick Dot for Dot. You have to do this for each image. Now you will see how it looks in some image viewers that pick up the setting.

Probably you have this setting different from your other images.

RE: Image size
Ofnuts and Rich,

Sorry, I am not very good yet with pixels, aspect ratios and the whole 9 yards. It is all new to me. I should have asked for clarification with some of your responses, I apologize for that.

That particular image I posted was tired and retried, but whatever I started with It exported close to thumbnail size. However I understand it sounds weird. Anyway I got it working OK now. Starting to understand what you all are saying. I appreciate you taking time out of your day to help us beginners. Thanks a bunch!

RE: Image size
Nope, unfortunately I did not have that defining moment when you say "AW that's the problem". It just simply started working. I didn't do anything different, I just tried it again, and it worked. I knew I was on to something this time cause the progress bar on the bottom actually loaded and prior to that it didn't, it just exported instantly, too fast to load a large image.

Gimp overall is coming along OK, it is starting to get fun now.

Seriously, I really appreciate your time and help. Sorry to have bothered you for nothing. But on the other hand your answers were very informative. Thanks again!
