GIMP :: Resize Image With Quality
Jan 19, 2012I seem to be having a very tough time dramatically resizing an image but keeping its quality.
I want to go from a 160X158 image to 32X32, how i can do this while retaining quality.
I seem to be having a very tough time dramatically resizing an image but keeping its quality.
I want to go from a 160X158 image to 32X32, how i can do this while retaining quality.
My problem is related with the quality of a image.
My question is how to maintain high quality (original quality) of a image after resizing it?
If i resize it with same ratio like:
2816x2112px to 1600x1200px (4:3)
2816x1584px to 1920x1080px (16:9)
Mainly i use scale image option in Gimp. But now i need to resize many images for my work so i tried David's Batch Processor to resize my images. After using it, i found there is some quality promble with the resized image.
Then i tried, the scale option with, use quality setting from original image and JPEG quality parameter is 95, in gimp but the problem is same. I did it with also with David's batch processor- JPEG quality parameter is 95.
Other thing is that, the original image 2816x2112px (4:3), size- 3.6 MB is displaying in image viewer with 47% and the resized image 1600x1200px (4:3). size- 1.2 MB is displaying in image viewer with 83%, So my questions are: How can i check the quality of a image after resizing it, means the image is exactly same as the original? Or Is David's Batch Processor maintain the original quality of the images after resizing?. I realy need to resize many images for my work.
Paint.NET informs me that my photographic images are 2592 x 1944 pixels with a 72 pixels/inch (28.35 pixels/cm) resolution measuring 36 x 27 inches (91.44 x 68.58 cm). Why is it that printed copies at 15 x 10 centimetres using the File>Print facility directly in Paint.NET are far superior to those using Image>Resize before printing (without saving the resized image)? Is there any means by which I can intervene to resize the image myself without losing the original quality?

I tried copping and stuff but I can't seem to use the tools right. I wrote a lengthy detailed version of this but figured it was too much to read so I am editing/cutting all the details out
Also the resize part. nevermind I got it figured, I just had to resize the image and the canvas follows suit. I didn't know that, thought I had to resize canvas first then image like in photoshop.
When Rotating or Resizing an image I have recently run into an issue. This is new behavior so I think I either have something set incorrectly, or it came in with a recent re-install.
When Rotating or Resizing, and setting Clipping to Adjust, it always Crops the image.
In other words: If I were to attempt to stretch an image bigger than 1000x1000 to say 1500x1500 it appears to do all the correct calculations, and does stretch the image, but anything outside the original 1000x1000 disappears.
Likewise if I were to attempt to rotate an image that were say, 1000x1500, 90°, I would end up with a rotated image 1000x1000 in size, and transparent/background for the balance of the original 1000x1500 sized image.
I've tried uninstalling/reinstalling (it remembered all my settings, so I don't know how much good this might have done), setting the Clipping option to Clip, then Crop and back to Adjust again (also with no result).
I've been trying to resize an image and tried Gimp 2's interpolation method but nothing happened. I increased the size to 150% with 153 pixels (I think). Did I do something wrong or is Gimp just not good for interpolation?

View 1 Replies View RelatedI've recently started trying to learn how to use GIMP through making signatures, and for the past 2 weeks or so, it has been going fine.
Today, when attempting to resize the large image down to signature size, even though the preview shows a good quality render, after it scales the image loses all quality. Whats more, thinking it might just be a poor image, I tried to resize previously succesful images and got the same bad result.
Here are some screenshots showing pre / post scale [URL]...
Preview there is fine, and shows a good quality render (exactly what I'm looking for)

This is the result
I understand that the aspect box is unticked, but even with that selected the image became distorted
I have also tried cubic / Sinc, both resulting in blurry picture.
The most frustrating thing is that the preview shows that the picture can be made that small and retain it's quality, and up until now this has not been an issue.
I can't find a way to resize (make smaller) a clip that I have copied and pasted from another image. Here's a screenshot:

Is there any way I can scale images down in size, whilst keeping the quality of the image? I am a Media teacher having to use this software with the class and they must have high production values for their controlled assessment. However, I do not know how to get around the problem that all the work is predominantly blurred because students have scaled down the pictures resulting in horrendous blurring.

When I went to make my business cards, I had the settings at 2in x 3.5in 300dpi in GIMP.
When I go to print them as business cards using GimpLabels, you can only see the very top portion of my image. After switching the ruler settings to pxl (in the corner) I noticed my image is actually 2500 pixels by 3500 pixels. Obviously a business card is not that big. So... Is there anyway to easily scale this to the correct size?
I actually have about 10 different versions of this card I have to print.... So it would really suck if I'd have to go in an manually scale every one of them. It would be nice if GimpLabels would scale it itself you know?
So I couldn't think of a better place to put this. I have something that I'm thinking of having professionally printed. What are the steps I should take to make sure I produce a high quality image? File format, Dpi and so forth. Make a list of steps to creating a high quality image file that will look good printed from a print shop.

View 1 Replies View RelatedOk i just installed Adobe Illustrator and want to convert some images i created in Photoshop to vector graphics so i can resize the image without it getting blurry. So i saved the image as a png file and opened in Illustrator. I chose high fidelity photo from the image trace menu and now the traced image is blurry. Here is what is happening.
The image is 300dpi png file format, i tried eps file format and same result. Resizing in Photoshop causes the images to get blurry, so i installed Illustrator to convert the images to vector graphics and resize without losing quality but this problem has now surfaced. How do i solve this?
In previous versions I have been able to resize the canvas and then resize the image. For example resize the canvas to 250px x 250 px. Then resize the image to the same.
Here is the process I am using:
Duplicate the layer and then hide it. Resize the canvas (Image > Canvas Size) to 250px x 250 px. Un-hide the layer and then resize the image (Image > Image Size). When I go into Image>Image Size it says that the image is already 250px x 250px. However if I try to transform the scale the image is the original size and not 250px x 250px
The reason for needing this is I resize image size (in bulk) and the canvas size using the batch process (file>automate>batch) and actions. I loaded the actions file I used in previous versions, but that did not work correctly. I then went in to do this manually and got the same results.
I want to know how to resize a photo without loosing quality....... in the image resize box the is a check box that says maintain file size ......what does that do .
I have tried to resize using it and the file stays the same as the original.
A while back I took a Photoshop class and remember a lesson on where you could select a region of an image and save it for the web with a high quality and select another region of the same image and save it for the web with a low quality, so that the focal point was saved with a high quality and the background was saved with a low quality. I have no idea where my notes are from this class and can not remember at all how to do this. Can anyone direct me to a tutorial about this?

I am having trouble with Image/Resize/Image Size in PSE7. In the past I had a document size of 4x6. When I wanted to reduce the # of pixels, I just entered new #s and the document size remained the same. A couple days ago I changed both the document size and canvas size. I cannot get my old settings back. I even uninstalled and reinstalled the program, I also have PSE11 on a trial basis and it also only sees the changed settings. I've tried changing Scale Styles, Constrain Proportions & Resample Image, in addition to changing the Canvas Size but cannot get it to work like it did before I changed the settings.

My question is it possible to verify the result using photoshop or some other tools? How?
My college said it is hard to check if an image looks different because of image resizing or because of quality loss or because of both. He said I have to create some log files to trace the result. It is a little too much work for me.
I've noticed that every time I save an image in GIMP as JPG the qualityslider bar defaults to 85. Even though I keep changing it to 75. If thisnumeric value is a Photoshop equivalent like other GIMP features, then 85is probably a wasted effort. The research* I'm aware of* (note emphasis)says that the quality in JPG images saved at a level above 75 is"theoretical." In other words, the increased quality is there in technicalterms, but imperceptible to the human eye.

I'm using Gimp 2.8.2 on a Windows 7 machine.
I've been using GIMP to make GIFs and they were okay until one day I realized the GIF quality was terribly reduced after I exported it. But everything seemed fine when I was in the process of making it (I never use any color transformation I normally just crop and resize image and that's it) when I used playback the GIF seemed okay but once after exported, the quality was very terrible. I couldn't understand why.
Every single GIF I make ever since faces the same problem. The animation playback and everything seem fine. Just I can never export the same quality GIF like what I see in the playback, every time it ends up with a low quality one. I re-install GIMP but that doesn't work at all. I download the latest version but that doesn't change anything either.
I understand there's a plugin that can increase the quality of a low resolution JPG, smoothing out the pixel effect. which one it is, if it exists?

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?
View 1 Replies View RelatedIn this tutorial, we will be adding color and definition to "drained" images, which are lacking it.
This tutorial is similar in concept to 14Stones's Cool Render effect (simple) tutorial which can be found here. I discovered part of this method a while ago, and it isn't really a secret, so I didn't copy 14Stones.
Anyway, I will be using this image:
It's nice, but is lacking.
First, duplicate your picture.
Next, on the the top one, Gaussian Blur it by 5 pixels and set the layer mode to overlay.
Finally, Sharpen the bottom layer by 20 pixels.
I made an animated gif but the quality is not as expected. Especially the company logo (wifocarr)I made 2 layers wich have good enough quality but when I did the following thing:
- filters
- animation
- optimize for gif
the qualtiy really got worse.
