![]() ![]() 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! 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 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. We’ve chosen a subtle gray so as not to drown out the shadowing.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. At the end, should you feel the white background to not be adequate, you can highlight the Background layer, select the Bucket Fill Tool, and proceed to add a bit of color.Other than that, select the GIMP logo layer and move it into the position you want in the thumbnail. If you choose to do so, the directions are the same. It’s not necessary but we decided to add a shadow to the GIMP logo.Merge Down the Drop Shadow layer on top of your text layer.To avoid a shift in the image, uncheck the box marked Allow resizing before pressing OK.However, since our background is white, black is perfectly fine. You could change the color of the shadow to make it more visible on the backdrop, say for instance if your background was black it would be better to choose a brighter color.For the thumbnail we selected ‘ 8’ in both X and Y, ‘ 20’ in blur radius, and cranked the opacity to ‘ 100’.We can then drag the image off to the side so that it’s out of the way for our text until we need to reposition it.If you follow the instructions illustrated above, adjust the image width and height to 200px. The layer image is a 1200 x 1200 which is much too large for our primary image at 680 x 400.Select the GIMP logo you downloaded earlier and click Open. So, open the “File” tab and this time select Open As Layers… just as we did for the arrow during Image Rotation. The best thing to do is add your additional layer now, that way once we begin adding the text, we’ll be able to adjust it so that it doesn’t block out the image. ![]() You can choose to color the background however you like using the Bucket Fill Tool in the Tool Doc, but for now, we’ll keep it white. We should now be looking at a blank (white) canvas.As for the height, we’ll keep it at 400px. Our thumbnails are never any larger than 680px width, so we’ll set our image size as such. ![]()
