GIMP :: Image Scaling Asymmetry
Apr 21, 2012
When I shrink an image, the result seems to be distorted.
I have an image 850x850.
I go: Menu > Image > Scale Image > and set height and width to 306 px
I get the same error no matter what scaling algorithm I use.
See images below, the one scaled by the GIMP has the black circle noticeable shifted to the right hand side. The white gap between the red and the black circles is 6 px on the LHS and it is 3 px on the RHS (measured at the widest part of the circles) . To compare, I have also scaled the image using another image manipulation program (IrfanView) - it scales it properly.
scaled by the GIMP....
scaled by Irfanview...
Is there any setting that you think I may have set incorrectly to get this problem? (Under the View menu, I don't have any "snap to..." checked.)
The test source file is the scaleBug.xcf attachment.
I'm on GIMP 2.6.11, Windows 7 64bit.

What is interpolation when scaling images in Gimp? it is under quality. I see there are None, Linear, Cubic, & Sinc (Lanczos 3)... what are these and which one is the best one?? and does it matter which one e.g. are they all the same?

I've imported an image into gimp, I then have imported another image using File open as layers.
Once this second image is imported it's obviously far too large, I want it to easily sit within the first image.
However when I right click > image > scale image it alter's both of them at once. It does this whether I have both images showing or not.

I want to create a collage image with numerous large photos, each in it's own layer during editing. In order to fit, all the images need to be scaled down to varying degrees, but when I'm starting out, I'm not sure what scale each image will need to be. With the default, if I shrink them too much then they get pixellated when I try to enlarge them again. Is there a way of enabling gimp to scale each image, but drop this version and reuse the original data on future scale operations (ie a "lossless" scaling operation)?
Currently I'm having to essentially create the collage twice - first time various shrink and expands til all images fit together, then start again but just rescale once to the required size.
I presume I'm correct in thinking there's no record function in GIMP yet, so I can't record my actions to GIMP then just delete redundant steps and replay...

Is there a way to do this with "handles" and not in the Layer ->Scale command?

I have a design that is approx 9 inches by 11 inches @ 250 dpi. I would like to increase the print size for canvas to 16 x 20. My question is, after I create my new image for 16 x 20, if I scale up my picture (design) layer to 16x20, will that produce poor quality? Or am I just "stretching" the pixels?

Is it possible to scale / resize a layer or selection about its center? I saw requests for this from 2010. This has to be possible.

Just a question about scaling and pixelation. I've been doing some 3D models in ZBrush at a 960x960 size, and wanting to scale them down to 48x48 size, very small icons for a game engine.
Anyway I started doing this with just normal scale in GIMP, but the picture just turned out like a big blur. With further investigation I found GIMP add-ons, Liquid Scale and Step Scale (I think that was it's name) where you can step down the scale of the picture and sharpen it during step downs etc.
Still not having much luck, I can get it to look better, but not good, still very pixelated and blurry. The required result I want is something along these lines - Picture
Using high res picture, I've tried PNG, GIF, PSD with not really much luck.
PS: Attached is the original model GIF and the resized picture.

I have a 4608 x 3456 pixel photo, trying to resize to 960 x 190 pixels for the web. I tried cropping and and scaling the photo, but it is still coming out very blurry, and still not sized properly.

While Gimp is great, one of its biggest downfalls is the way in which it handles resizing and rotating images.
- Open a new image.
- Draw / manipulate / play with your image.
- Add layers, colors and images included.
Now, let's say you want to trace an image that's at the bottom of your layer stack. But that image is the wrong size, so you select the area you want to trace, drop its transparency down to 10%, and attempt to scale it to the size you've been sketching on the layer above it. The moment you attempt to scale / rotate it, it shoots back to 100% transparency, which is unintuitive because you can no longer see what's beneath the layer. In Photoshop, an area that is being scaled / rotated stays at the transparency you gave it.
Is there a way to make this NOT happen?

I am designing a logo, and have used a gimp script to create (a) the text that I need, and (b) a ring to enclose it. The ring is in a separate layer with a transparent background (I set the entire background to Alpha), and it surrounds the text. I created the ring using a script to transform a letter 'O' into a 'glassy' style object, which I then resized into an oval of the correct size and shape using the 'scale layer' tool.
The logo looks OK, but would be much improved if I could make the surrounding ring thinner. The ring has a 'glassy' effect which is just what I want, but it is a little on the chunky side. It would look much better if I could transform it to be about half the thickness that it currently is, to match the slimmer text inside the ring. I would like to do this without losing the 'glassy' effect of the ring.
I have already tried creating the ring with the thinnest font I could find that gave me the right shape, but this doesn't go quite far enough. Is there any way that I can thin the ring so that it keeps it's size, position and 'glassy' effect, but ends up with a thickness of about 50% of it's current width? Effectively, I just want to transform a fat ring into a skinny ring!

Ive figured out how to scale images and remove their backgrounds, but when I go to paste them in a new location I lose their scaling.
What I'm trying to do is put multiple pictures (the items are scaled to actual size, which is important) onto a single 8.5 x 11 page.
So, I've taken some of my pictures, opened their files scaled them to where they need to be, and then removed the backgrounds. I saved that as a new file.
How would I then take those files and place them, with the scale I made them, into something that is this 8.5 x 11 page size.
When I try to do it now, it doesn't keep the scale.

I have been using Coreldraw for a few years now but I have never had a problem with scaling images. I created a circle and added some shapes to it. There is spacing between the shapes and the circle and they do not touch each other. When the image is at page size and it looks fine. But when I scaled it down using the shift key the shapes in my images touch the side of the circle and the spacing is gone. This is not what I want. There needs to be spacing between the shapes and the circle. I have included a sample of what I am talking about. How to make Coreldraw scale images properly?

New Responsive Scaling feature is great.
It's enabled me to add an Edge Animate file to my responsive Wordpress site using the Edge Suite Plugin.
Only problem for me is that although the 3.7MB file I’ve created scales perfectly on all devices it struggles to play on smartphones. (I assume it's too big and too power hungry to play smoothly on smartphones - even since I've added a pre-loader.)
So, in an ideal world, what I need is a separate low res Edge Animate file that only plays on smartphones.
Failing that, I’d be happy with a 'Down-level Stage' image which could replace the Edge Animate animation.
For a moment I thought I’d found a solution when I came across this Adobe TV movie: [URL]
Unfortunately this clever solution only works when the new Responsive Scaling feature is NOT selected. As soon as it is selected, the animation no longer changes from one layout size to another when the browser window is reduced.
I don’t mind whether the fix is in Edge Animate, Wordpress or the Edge Suite Plugin - I just want a solution!

My knowledge (lack of, really) with content aware scaling is that 1st you create a new layer of the background and then rescale accordingly. I did the following: -
1- Created a 2nd layer
2- used quick selection tool on my main subject ( a person) and named it.
3- deselected the selection
4- Edit menu --> Content aware scale
5- resized it to something smaller (chose my previous named selection channel).
6- Pressed "Enter"
The result is that I can now see 2 images; the smaller sitting on the larger. What now? All I want is the smaller image. If I throw away the original layer what I end up is the new layer with the white and gray default background showing as part of the image (which ends up being printed as well or if saved looking as is with the grey-white. Is what I should do the obvious--cut out via cropping the un-needed (gray-white) part?

I have been given an incomplete plan view of a site with access roads and have been asked to extend the roads to meet up with a main road off site. Not having any survey points I figure the most accurate thing to do was to screenshot a Google map image, import it into my drawings and trace it. I'm struggling to scale the map image to my existing drawings.
The problem I'm having is when i click the image to scale, it obscures the view of the drawing, so I can't see anything to reference. Is there a way to make the image transparent? Or to have it permanently at the back.

I have used paint.net for small photo touch-ups of my daughters. But now I'm starting a small business and actually starting to use more tools.
I had our logo done by a graphic designer and to save on money I am doing the layouts for ads, flyers, business cards etc. When I copy our logo into a new layer it is super big compared to my canvas size. I cant seem to figure out a way to scale it down in ratio. When I click on the corners it allows me to scale down, but not to ratio. When I select image-resize (Ctrl+R) and do a percentage it cuts off portions of the logo or select by absolute size it wants to change my canvas size.

Scaling - for some reason the image get distorted after scaling. see example:
Each time I scale it'll do it differently. this time it made the right side thicker.
Alignment - the bounding box has offset and when aligning it doesn't align the objects right:

I'm rendering an equipment shelter that sits atop a gravel pad. I've picked the "Gravel Crushed" material, and it looks OK, but I'd like to be able to scale the material so it isn't so "fine". I'd like it to be more coarse.
How to change the scale of the material?

So I am trying to make a site map for a building my buddy just bought. I found a lot map on the city's online database, cropped it to the area of his lot's block, and saved the image file. I then opened up a new autocad file and xreferenced the image. I know the front of his building on the site is 45' so I made a polyline that is the length of the facade over top of my xref image. Then I selected the image, used the scale command, selected one side of my polyline as a basepoint, used reference, entered 45' as the known length, and then selected the other end of the polyline. My image scaled but is now incredibly small. So small that the entine site isn't even 1". I keep trying but I'm doing something wrong somewhere.

I have a top banner for a website - the website is fully made in Edge.
The banner is 540px high, and 100% width. (Stage width is also set to 100%)
Now inside this banner, I want a large image to show.
The center of this image should correspond to the center of the banner.
The width of the image should be 100% of the banner. (Hence 100% of the browser window).
The height of the image should remain proportional to the width of the banner, i.e. no distortions. (Was using auto before)
The overflow should be hidden. (So basically the image is always 100% width of the browser window, and the height overflows both both up and down).
Somehow in ver 3 of Edge Animate I can't get all these options to work at the same time - can't use 100% width and auto height for an image anymore.

I am a C# developer and not very familiar with coreldraw(when using with c#). My problem is that i am programmatically importing image on a curve using the following C# code.
d.ActiveLayer.Import(imgpath);// image path is path of the cdr file
var v = d.ActiveShape;
v.SizeHeight = 20.00;
v.SizeWidth = 15.00;
v.AddToPowerClip(s);
Now when i run this code the image gets placed into the curve bit it gets stretched vertically means the face of a student(that comes from imagepath) get stretched vertically..When i do this Manually with scaling and sizing ratio locked it gets properly inserted in curve....

We are designing some web graphics for a friend. By "we" I mean me and a guy who lives on the opposite coast.
He did the initial page layout/design as a PhotoShop tif, at 300 dpi, in layers and about 5 inches wide. The idea, on his end, was that it would be a small file size and, therefore, faster to download on my end. With me so far?
Anyway, I'm suppose to convert it to 800 ppi wide, 72 dpi, jpg. Sounds easy enough. Or not Do all the scaling and now the graphics don't look right. None of the layer effects are right!
How do I scale his graphic, for my purposes and, once it's the size I need it, have everything look the way he created it?
Example: Text at that 5 inch wide, 300 dpi size with a one point stroke on it looked find when the graphic was 5 inch wide and 300 dpi, but at 800 ppi wide and 72 dpi, it's all wrong
Is there a preference or something I should be clicking somewhere and I'm just missing it?
