Resolution sizing in Gimp, PLEASE help, getting really frustraited.?
You can`t change`s the resolution of a picture very good with most photo editing software`s.but you can try this it may help you to do what you want to do. If you have a printer and a Scanner and your picture is already in your computer you can use the printer to print it out with the small resolution and scan it back into your computer at a higher resolution of 300 or 350 and with a higher resolution you can make your picture bigger without it getting fuzzy or getting pixelated and use the picture with the Higher resolution to make a poster. I hope this can help you.
How do I increase the resolution of icons using Photoshop without increasing the size?
Have you ever tried resizing a image to make it larger? This usually results in loss of quality where the enlarged image looks blurry and unprofessional. If it was possible to resize a small image and make it larger without losing quality.Method 1: Using Perfect Resize with Adobe PhotoshopPerfect Resize is a software that allows you to resize your images smartly. It is available as a standalone software as well as a plugin for Adobe Photoshop.open the image file you want to resize in Photoshop. Simply go to File » Automate and select Perfect Resize.This will open the image in Perfect Size application. You can choose a preset from the left hand menu or enter your own size in Document Size.After entering the document size, you need to go to File » Apply to save your changes and apply them to the file in Photoshop.Now you can export this file by saving it as a web image.That’s all, your resized image will look much better now than the normal resize.Method 2: Using Free Software GimpGimp is a free alternative to Adobe Photoshop. It can also be used to enlarge images with minimum quality loss. However, we should warn you that the result will not be as good as Perfect Resize.Open the image you want to resize in Gimp. Simply go to Image » Scale Image. Enter your desired dimensions. Under the Quality section choose Sinc (Lanczos3) as Interpolation method and click on the Scale Image button.That’s all, you can now export this image for the web. Here is an example for you to compare. The image on the left was resized using bicubic resampling in Photoshop. Image on the right was resized using Sinc (Lanczos3) as interpolation method. You will notice that there is very little difference in both images.#This method Collected from Google.
Is there a free online tool to change an image's resolution (DPI)?
Technically speaking, images don’t have a DPI. The DPI is determined by the device that renders the image. If you draw a 100x100 pixel image in a 1″ box, it’s 100dpi. Most rendering devices have a fixed resolution, so the image is generally scaled to fit. For example, a laser printer might have a fixed 600 dpi resolution, so the image will always be 600 dpi, but the number of device pixels per image pixel will be variable (draw that 100x100 pixel image in a 1″ box, it’s 600dpi but each pixel in the image is drawn using 6 printer pixels).Sometimes, it’s possible to store an the image file a preferred output size. This will either be stated in dpi, but just as often in inches or centimeters. Normally, this information is ignored except when the image is imported into an application doing page layout, so as to set the default scale of the image relative to the page size.Depending on the image format, you can set these values with tools like ImageMagick.In your case, it shouldn’t be at all relevant. Your silkscreener should be asking you how big to size the image to. If you are producing the artwork, you should make sure that you create art that is originally 300dpi or greater. That is to say, if you want the image to be 9″ wide on an T-shirt, the original version of the image should be no less than 2700 (9x300) pixels wide.
Why did GIMP change my photo's resolution from 96 dpi to 72 dpi, even though I didn't change any settings?
DPI is NOT the resolution.or your image.Dots per inch (dpi) is mostly a legacy term to describe how printers resolve detail. How many dots per inch it can print. It is largely meaningless to us as digital photographers.Image size & resolution - 72dpi or 300dpiAs the article above says… saying your photo is at 72 dpi is like saying your house is 65mph away.GIMP just has it as a default value and as mentioned above, it is largely meaningless as we now use ppi (or pixel per inch) for describing the how big your can print a digital image while maintaining good visual resolution.
Gimp: how do i increase the amount of pixels?
If you do that the quality of the image will get worse not better. It's called "resampling" - it always makes images look worse. There is no software that can improve the quality if you resample - not GIMP, not Photoshop - not any software. It's impossible. The most recent version of GIMP is 2.8.6 from here http://www.gimp.org - but it won't help you, since what you want to do is not possible. There is no paid-for version of GIMP - GIMP is open source software - it's has always been free, and always will be. Here's an example done in Photoshop - http://i.imgur.com/8XiKJMJ.jpg - as you can see the result is 5hit. The more you try to enlarge it, the worse the problem gets, and the blurrier the image. If you want to do it in GIMP click Image > Scale Image - or in Photoshop click Image > Image Size. You might be able to get away with resampling let's say if you are only doubling the size of the image (200% enlargement), but the quality will still be worse but perhaps still acceptable. Results will always depend on the quality and resolution of the original. Read this for more info http://www.graphics.com/modules.php?name... - this is for Photoshop but also applies to GIMP as both are raster image editors. In GIMP use "Sinc (Lanczos3)" for the upsampling/interpolation method.
How do you increase the DPI of an image?
The first thing you should consider is whether or not you need to increase the size of the image. One common misconception is that you want the image PPI (pixels per inch) to match the print resolution DPI (dots per inch). But this is not the case. Taking my Epson R2400 printer as an example, the printer prints at 5760 x 1440 DPI but the optimum image resolution for the printer is 360 PPI and you can certainly print 250 PPI images without experiencing any substantial degradation of the print due to pixelation (printing larger blocks having no image detail).The second consideration is viewing distance. A billboard (highway sign) does not require a lot of print resolution. Even though the print is very large, when viewed from a distance it doesn't convey a lot of information. So the DPI can be a small number compared to a photo viewed from a foot or so away.There are circumstances where large prints are viewed close-up. Commercial display works in public areas like airports are often life size or larger presentations often viewed at very close distances. For these circumstances the image needs to be captured at a very high resolution. Such work is best suited to medium format or large forms cameras capturing 50MP images and much higher. There is no real way to get that quality from any current 35mm dSLR (or below).At least one other answer mentions fractal enlargement. My experience with this technology is that it can do well when important image details are very sharp in the image. But missing details cannot be created so this type of tool has a limited range of application.
Is there any application that sets image resolution from low to high?
Yes, there is one tool- Neural network image super-resolution and enhancement, which uses neural networks to completely to increase resolution, remove all JPEG artefacts and enlarge the photo 4x. It’s extremely simple and does everything online.Here how it worked for me. On the left - I enlarged manually, right - with the tool.
How can i increase an image's pixel numbers ?
What you should have done is scan the image at a higher resolution - that would give you more pixels. When you open up your scanner software look for the resolutions settings and double it. You can resize an image using almost any image editing software such as Photoshop, GIMP or Paint.NET etc. But resizing an image upwards can be detrimental to the quality of the image - although a small increase like you want shouldn't make too much difference. In GIMP, click the crop tool, then in the tool options dialog check the fixed aspect ratio option, and type in the ratio 1:1 - this will force the crop tool to crop as a square. Click and drag the crop tool from the top left of the image as far as it will go. Move over the centre of the crop, click and drag your mouse to move the crop to the position you desire. Press the Enter key to accept the crop. Then click Image > Scale Image > replace 259 with 600, this will make the other dimension 600 pixels automatically. Click Scale. If the image has blurred slightly (as result of scaling it upwards) you could do a little sharpening - click Filters > Enhance > Unsharp Mask > click ok. GIMP is free - http://www.gimp.org
Staples says my image has a resolution of less than 180 PPI but on gimp i changed it to 1000 PPI?
Changing the PPI won't increase the resolution. PPI is not a measure of the actual resolution of an image. PPI is an output resolution (for computer screens). The true resolution of an image is measured in megapixels, your image 1441 x 907 is only 1.3 megapixels. What you need to do is give them an image at the maximum size it came out of your camera. If you use a point and shoot, make sure the settings are so that the maximum file size and quality is chosen. If it's from a phone camera, then 1.3 megapixels probably the biggest size available. An image 1441 pixels by 907 is not big enough for anything more than a small print. If you are enlarging it, it will look blurred. If you increase the PPI, it will still be the same size image, and still blurred when you print an enlargement. If you rescale the image by resampling it (to make more pixels) the image will still be blurred. You see where this is going - right?
