As several of you know, I'm working on a few projects right now, and the one that has me stuck is a little German village for a display at a nursing home. Doing the village from Kaukapedia, www.kaukapedia.com/index.php?title=Bastelbogen:_Romantische_AltstadtAs these are models from Hubert Siegmund, I thought I would do an internet search and see if there were any other models that might fit in. I found this: www.kartonmodellbau.org/publikationen/mittelalterliche-kleinstadt.shtml.enYou have the choice of downloading two plates from this village. The jpg's are low resolution, but the pdf's located up in the text, are very nice, with walls, a gatehouse and a couple buildings. They blow up very nicely, just viewing the pdf's, so I thought I'd have a go with Gimp. Several wasted pages later, I'm no closer to figuring this out than when I started. What process should I be using? Thanks

So, you are trying to scale these up? You can either import the pdf to gimp and go to Image and Scale or you can take a snapshot of part of the pdf and paste it into a gimp page. When you paste something it is its own new layer (with "marching ants" around it) so go to "Layer" and "scale." I use "View" to"show grid" when I'm scaling. You can "configure grid" Hope I understood the question.

First: What you want to do?
Once you know that, at what point do you got using GIMP?
Common problems using GIMP and PDFs:
What is the resolution that you are importing the PDFs is GIMP? The default is 100dpi, which is very low for carboard modeling purposes. 300 dpi is a better setting.
What is the size of the file you are working with? Some calculations may be necessary. At 300 dpi, an A4 sheet should be an image of 2480 by 3508 pixels.
Then you can measure the buildings to know at what size they'll be printed. 300 pixels will measure to 2.5 cm once printed (what you Americans call a "imperial inch"). There is a measure tool in the GIMP tool panel.
But really, firt you should tell us what you want to do.

On the two additional pages, I am wanting to scale up. Since the original Kaukapedia files were printed 'Fit to Page', they are not exactly 1:160 as indicated. The additional files are at 1:300.
When I enlarge the pdf to 175%, the distances from window top on one level to the window top at the next level up matches pretty close the printed pieces I have from the original site.
On the additional models, the pages are laid out with markers that look like they should be the corners of pages that were put together. Instructions are in the margins. I think that if I can get each page divided into two pages, I can adjust print to get where I need to be.
On the right hand 'page' of the one page there are two houses in vivid colors. I intend to wash out the color on them so that they will blend in with the already completed models.
I was just using the pre-set settings, which from what I'm reading here was 100 dpi, If I open at 300 dpi, that may fix my problem.

Open the PDF at 600dpi, since it has two sheets of miniatures per page the increased resolution will help.
Cut the image at the marks using the Crop tool.
Scale the image to the desired proportion, you may need to do some calculations to get the right size.
Print.

I'll give that a try tonight. Thanks

Thanks, guys. I'm still a Gimp-idiot, but I got done what I wanted done.

Gimp does throw curves from time to time. It is easy to get rusty and forget how things work if you don't use it often. Thank goodness for "undo"

You'll get the hang of it. What I like of GIMP is its free. It might not have the bells and whistles of photoshop but once you get used to it... It's great. Like they say go with the pdf file rather than the jpg since that has the better resolution when scaled up will not be mmmm blocky or pixallated.
Import to GIMP the pdf file. Select the half the page/part you want to scale up (I'm going by what you want to make one page into two). go to Edit>Copy (only copy the image on that one layer) or Edit>Copy Visible (copies what you can see regardless if they are on several layers) Create a new blank file with the appropriate size and resolution (most use 300 dpi) in that new file create a new layer (I don't use the background layer) with your mouse on the layer channel (window) right click and select New Layer... Mouse over the your working window (window where the image will appear) go to Edit>Paste Now the image should appear as like a ghost layer on the layer channer (Do not anchor it yet). On the working window (or whatever you guys call it) Go to Layer>Scale layer and adjust the scale... if you think you got the scaling right then anchor the layer. If it turns out wrong just select the entire layer and delete the image on it and repaste your image and start to scale it again.
Tip what you may do is in the original file image you can measure the parts... and measure the pasted rescale image (on the other file) using the Measure Tool in the tool box and calculate the percent you have to scale up. The scale layer tab or window can do percentage (or other type of measurement) rather than pixels. (I'm trying to do this with one of my work looking at the tabs and menus you need to open in GIMP).

Well, because I am not good at it yet, I didn't know where to find 'Scale'. Until they mentioned 'Crop', I didn't know it existed either.
But got it done. Probably just a tiny bit too big (83% larger instead of 75%), but not so bad anyone would notice. Two of those pages were city walls, so it didn't matter on them at all. One page was the gatehouse, so being a bit larger is probably better. Last page is two townhouses, and they don't look bad.
Thanks again for all the help.
