When you reduce the image quality of a jpeg image , How exactly is it reducing the quality? is it applying file compression , reducing bit depth or is it reducing the sampling rate of the image? or anything close to the above....
View 2 RepliesMy 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.
When saving a jpeg it gives the option of inserting a number on quality. I have mine auto set to 10 but I have no idea whether 1 is better or worse or what number I should be putting in to preserve the original quality?

I have set the size to 24000x30000 pix at 1000 dpi..now my problem, when i go to save the gimp file as a jpeg i get this error message "JPEG image plug-in could not save image"
View 3 Replies View Related when saving an image as a JPEG I would click "Save As", select my folder and the Image Quality dialog box would pop up and I would then select 12/Maximum as the image quailty and hit "OK". Thereafter, every time I saved an image, Photoshop applied the same settings as the previous save i.e., 12/Maximum was pre-selected and I would just hit OK and move to my next image.
However, since yesterday Photoshop is no longer pre applying the last setting used and is defaulting to quality 8/High every time. Si everytime I save, I am now having to slide the slider to 12 which is kind of interrupting my work flow.
I have tried delete my preferences settings in the hope that this glitch would be fixed by resetting the program, but the problem persists.

View 5 Replies View RelatedI'm using gimp 2.6 on ubuntu. i have some pictures i would like to enhance.
There's that image image 1
and i would like to make it look like image 2
As you can see the second image uses only about 7 or 8 different colors and the outer lines are nice and smooth not stuttering.
Is there a way how i can change the first image to something like the second one, maybe something like replace 10 different colors which are similar to each other with only 1?
I tried and played with the options (bucketfill, posterise, or the cartoon option from artistic menu, increase contrast, brightness etc...
Is there an option to smoth the outer lines etc? i just want the dog, the rest of the background is not so important.
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.
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.
View 3 Replies View RelatedI've searched for hours for directions on how I can use my 3D template in GIMP. I purchased the template from a stock photo site. It already does have a 3D appearance with proper shadowing etc. I am creating a 3D book cover. So I only want to fit the jpg image I created,. the flat 2-D one, to my blank 3-D book cover template. I also want to add text to the spine of the book, or an image of this text if that's how it's done.
This would be the same process I think with any sort of 3D template and 2D image. For example, some people create boxes and other items in 3D. But I don't need to know how to create the 3D effect. I already have that in the template I purchased. I just need to know how to add my jpeg image to the template so that it fits properly.
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 2 Replies View RelatedI've been a GIMP user for a couple of years and have just encountered a new and unexpected problem with version 2.8.4. I'm attempting to export a file to JPEG format, and am receiving the message:
"Saving 'FILENAME' failed: JPEG image plug-in could not save image."
I ensured I had adequate disk space, tried saving to different locations (including other drives on our network), tried resizing the image, and nothing will work. The message just recurs each time, no matter what I try.
I have a jpeg image of a motorcycle on a pure yellow background. I want to make the yellow transparent. Naturally there are a lot of spaces within the motorcycle image that contain yellow.
I followed instructions I found...
Removing the background of an image
1) add an alpha channel to your layer
2) use colors/color to alpha and use the background color
This results in the checkerboard being applied to the motorcycle, not the yellow background. I assume that's okay.
This makes all the pixels with the background color transparent, and those with a close color partially transparent.
Then:
- select the background with the magic wand,
- grow the selection by a couple of pixels to ensure that the border of the sprite is in the selection (the most important work of color-to-alpha is on the border pixels, so they shouldn't be protected)
This selects only the area outside the bicycle, but I don't mind reselecting smaller areas, if I can.

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 trying to find a faster way to save my images. I shoot in raw, save raw images as jpegs after editing them in Camera Raw. I am using Photoshop CS6 on a Mac version 10.7.5. When I save, I either have to save as a copy of the exisiting image, or replace the image I'm working on. Other forums I've read said to make an action to save and create a function key to make this process faster, but my function keys aren't working, and playing the action I've created still makes a copy of the image.

When I try to reduce the image size in Illustrator, the dimensions are still the same when I upload it?!?!? It is quite a complex design.
Using Illustrator CS3
I have an image that I took in RAW with a Canon 5D. I then masked a large portion of the image using the adjustments brush. The result was what I wanted but the image is now very large. I exported the image to a DNG to retain editability. The resulting DNG is 53,679 kb. If I export the image to a JPG at 25% quality limiting the size to 2000 pixels on the longest edge I still get a 7,795 kb image.
I have had this problem with masking before. Is there any way to get rid of the bloat that the masking caused?

I'm using photoshop cs4
I am a fairly novice user of Illustrator. I have my company logo in an .AI and .PNG format. I need to "shrink" the image while perserving the image quality. I am trying to design an ad for my business and the file is too big for the dimensions of the ad in photoshop. When i attempt to reduce the file size (Edit--> Free Transform) I am able to "shrink" the logo down to fit (about 70% reduction), but it turns out very blurry and not sharp. The sharpen filter does not seem to work.
I have been told I need to take the .AI file, and shink the logo there, then converting to a PNG to be placed into the ad. I **think** I did this, but the image still turns out blurry.
I was given an image with these dimensions:
w: 13.89 x h: 5.56 inches.
I'm being asked to make it fit these dimensions:
w: 8.5 x h: 5.47 inches
How to achieve this without the picture looking stretched, in terms of it's height. Everything looks constrained when you just do the image or canvas resize.
