That will help the public to understand what the application is all about. That are needed for the development to move on and it also contains information Write tutorials on this website We have a procedure for writing tutorials too! Improve this website Creating websites that contain useful information is very important. Project page of GNOME is also of interest. Translate GIMP or documentation to your own language Contact the respective translator team for Write or improve the documentation The Documentation websites tells you all aboutĬontributing. Test existing features and provide feedback If you think a feature can be improved somehow, you can discussĬreate enhancement requests (the same way you report bugs). You don’t have to be a developer or a everyday user That you encounter is very important to the development, it helps the developers Report bugs (errors in the program) GIMP is not bug-free nor is any other application so reporting bugs Start learning about being a code contributor. Ways in which you can help: Fix bugs or program new features Our Developer Website is where you want to Please consider the time you give in assistance to others as payment. As in a friendly neighbourhood, everybody pitches in to help their In the free software world, there is generally no distinction between users andĭevelopers. ( GPL) license, and historically part of the GNU In this example, we reduced our image size by changing the resolution from 300 to 72ppi and changing the pixel dimensions from 3000 x 2000 to 600 x 400px.Software, mostly licensed under the GNU General Public License Sinc (Lanczos3) - The Lanczos3 method uses the Sinc mathematical function and performs a high quality interpolation.Ħ. Click the "Scale" button to accept the changesĬongratulations! You have now successfully changed the size of your image! Sometimes this method is called “Bicubic”. This usually gives the best result, but it naturally takes more time. What does this mean? Basically, GIMP will discard any unused pixels in order to reduce the image.Ĭubic - The color of each pixel is computed as the average color of the eight closest pixels in the original image. First, we can change the resolution by typing in 72 and then, we can change the pixel dimensions by entering 600 x 400 as the width and height.īefore we finish, we will want to select our resampling method. Let's say that we want to put this image on our website, so we want it to be only 600 x 400 pixels and with a resolution of 72ppi. A Scale Image dialog box will appear like the one pictured belowĤ. Enter new Image Size and Resolution values With GIMP open, go to File > Open and select an imageģ. One may need to reduce the size of an image because the resolution is too high for web, the file size is too large to e-mail, or only a small image is required for a printed piece.ġ. The process of reducing the size of an image in GIMP is only slightly different than when enlarging. How to Reduce the Size of an Image Using GIMP In this example, we enlarged our image by increasing the image size from 10" x 6.667" to 12" x 8". Sinc (Lanczos3) - The Lanczos3 method uses the Sinc mathematical function and performs a high quality interpolation.Ĭongratulations! You have successfully enlarged an image! What does this mean? Basically, GIMP will have to create new pixel information in order to enlarge the image.Ĭubic - The color of each pixel is computed as the average color of the eight closest pixels in the original image. In this example, we increased the document width from 10" to 12" and the height from 6.667" to 8". We want to keep the 300 resolution, so all we need to do is type in image size dimensions. Lets say we wanted to enlarge this image to a 12" x 8" so that it can easily be printed and framed. Enter new Image Size or Resolution values A Scale Image dialog box will appear like the one pictured belowĤ. To see the Image Size in inches or a value other than pixels, use the drop down beside the valuesĥ. (Follow along by right-clicking on the tiger image above and saving it!)ģ. Note: When enlarging images, it is recommended to clean up dust and scratches or any noise before enlarging because these items may be magnified in your enlarged image.
