Resizing an Image in Inkscape

Steps I use resizing an image with Inkscape.

In GIMP

1. Open image, Ctrl + D to duplicate, close original image.
   
   
2. Image > Scale Image. Change resolution to 300ppi.
   
   
3. Save image as filename.png.
   
   
4. Open the image in Inkscape. Click image so arrows are all around it.
   
   
   
   
5. In Inkscape menu click Object > Transform. Click the Scale tab. Next to Width, click the dropdown that says % and change it to px. Check the box that says Scale Proportionally.
   
   
6. Make the Width and Height what you want and click apply. Click the X in the right upper corner to close the Transform dialog. Your image is resized but you need to resize the canvas around it.
   
   
   
   
7. In the Inkscape Menu click File > Document Properties and about mid-way down, click the bar that says Fit page to selection. Click the X up in the corner of Document Properties to close it.
   
   
8. In the Inkscape Menu click File > Export Bitmap. It will rename your image with a number. You can choose to rename it or just leave it as is. Click Export. Close the dialog.
   
   
9. Close Inkscape. It will ask you if you want to save it. It's saved. No further saving required.
   
   
10. Open the new png image in GIMP.

That is one of the many things i love about Gimp and Inkscape.They both work so well together.
Very nice tutorial on image resizing, thanks O! =)

Very nice tutorial "O". got it bookmarked for later when I get back into Gimp again.

Great. Any good how to for inkscape is much appreciated.

Thank you everyone. I still wish I knew more about using Inkscape and the only way I'm going to do that is to bite the bullet and go into Inkscape and learn.

A few things here about Inkscape:

When you open a dialog in Inkscape and have applied it, the dialog does not automatically close. You need to close it by the X up in the right corner.

When I export an image, I still see the dialog and wonder if my image is saved. If I click Save again it asks me if I want to over-write the one I just saved. Inkscape only saves exported images as png images.

File > Save will save the image in Inkscape's native svg format. When you open an svg image in GIMP, it gives you the option of resizing it.

SVG images are viewable on the web. Here's one you can click to experience the feature: Click

Every time I play with Inkscape I find advantages it has over the expensive software that I have. It's bitmap tracer is infinitely better than the one that comes with Xara Xtreme 5. In fact they try to give the impression that tracing bitmaps is very difficult and costly. The one in Inkscape works perfectly and i use the word with precision, perfectly. Inkscape also has better editing features than some of the other 'expensive' applications I've tried have.
I am curious though, Inkscape and Gimp use the same color orange in places on their sites. Are they connected (made by the same people) or totally separate? I do know they use the same palette files.

I don't know the answer to your question about Inkscape and GIMP gms, but I'm very happy they are compatible.

Here is a link to the Inkscape Manual. Inkscape Manual

It doesn't really matter, it struck me as strange they work so well together and use some of the same colors. But they work, that's all that really matters. I converted the inkscape manual to an exe file a few months back.

You can find some great InkScape tutorials at
http://screencasters.heathenx.org/

This site in turn will have links to other incredible InkScape tutorial sites.
I just wonder why they haven't created a tutorial in almost 3 months. =\
Anyways I have learned a great deal there.All of the tutorials there are in video format.

Yes I think his are the best by far.

Excellent link and very nice tutorials. I've watched a few, now to do some. Hopefully it will get me better acquainted with Inkscape.

Thanks Rod.

Any time, here are a couple more for you. =)

I tried to do as instructed in this post and it seems to not work as expected. I have an image that is 7x8". I opened it in Gimp and changed the resolution so it is displayed as 2x3". I then saved it as png and opened it in Inkscape and the image is still 7x8". The instructions are unclear at that point. I don't want to scale in Inkscape because then I am throwing away print resolution. How do I convert this to a high resolution image?

When you use Image → Scale Image in Gimp resize with x & y dimensions.
If you need print resolution (300+ PPI) use Image → Print Size instead.
Set resolution & dimensions before any image manipulation.

Does not work. I have tried both Print Size and Scale and in both cases, the resolution changes, the image is correctly reopened by Gimp with the higher resolution, but imported into Inkscape, there is no change in the image size relative to the page.

If print size (2 x 3") is important to you why does it matter if screen size is 7 x 8"?
Screen size and print size are not related. Changing resolution does not change screen dimension.
Try this make a 7 x 8" image, default resolution (72 PPI) in Gimp.
Check the image size at the top of the Gimp Window.
Image → Print Size change the resolution to 300 PPI.
Check the image size at the top of the Gimp Window, it should be the same as before. That is why Inkscape shows the size as 7 x 8" even though you changed resolution. The only difference when you change resolution is when printing.

Think of resolution not in screen size but pixel density.

What you are saying is true if you are only going to view on screen. I don't think what you say is correct in our modern age of "printing". Just for example, lets say I have an image that at 72 dpi screen resolution is too large for the journal page so I rescale it to smaller but higher resolution. For the print version, the journal printer is much higher resolution than a monitor. Thus if you are going to print at 300 dpi, there is no point if giving the journal a 72 dpi image and that is what happens if you downsize and do not increase resolution. More importantly, you make a pdf for the digital version, if you make it from a 72dpi image, when someone tries to zoom into the image to actually see what data is there from the postage size image in the pdf, they will see the 72dpi worth of data. If the original image is 300 dpi, they will be able to zoom in and see something closer to the actual data.

I believe your original problem was regarding why Inkscape still shows a 7x8" image even though you changed resolution in Gimp. The experiment I mentioned in my last post using Gimp points out why.

I always recommend using 300+ PPI resolution for printing, for screen only 72 PPI is sufficient.
I suggest further reading,
Coming to Terms with DPI, PPI and Size
Display, Printing, DPI and PPI

I am not sure what you are suggesting and feel like we are back to the beginning. The problem I am having is that I cannot figure out how to make my image 300dpi in Inkscape. I don't know of any image resolution control in Inkscape, only a size control which downsamples the image. The resolution control in Gimp does not appear to be saved so that I can open images with increased resolution in Inkscape.

"If print size (2 x 3") is important to you why does it matter if screen size is 7 x 8"?
Screen size and print size are not related. Changing resolution does not change screen dimension."

This is not true. The screen is 72 dpi. A 8.5x11" page (as Inkscape works and our printed page will look) is 612x792 pixels. When I import an image that is 784x694 pixels (I am using this example because that is what I am trying to do) it should import it at 10.9x9.6". {as an aside, Inkscape is actually importing as 90 dpi for reasons I don't understand. Canvas did this exactly as I am describing}. If I want that to appear on the page as 3x2" then I have to increase the resolution of the image to 260dpi. I have been preparing figures for journal publication by doing exactly this procedure in Canvas for 25 years until they stopped supporting Macs. Now I am trying to replicate it in Gimp/Inkscape.
