<strong>GIMP</strong> 270 Please pay attention that the file size is 6.8 KB, i.e. it is small, but the animation is not long, too. When you create a high-quality animation and banners, the file size may be 70 or more kilobytes. Sometimes such size is not convenient. If so, you can optimise a GIF file. When optimisation is in operation, you can view all layers and find all points that changed compared to the previous layer. Layers are cut leaving only the points that were changed. In this way, optimisation reduces the file size two or three times. Using a FiltersAnimationOptimize (for GIF) command you create a new image which you can save in a GIF format. Repeat steps 1–7. If you look at the file size, you will see that it is smaller. Note! You can unoptimise the file that was optimised. For this purpose, use the FiltersAnimationUnoptimize command. Practice Working with images We have already discussed how to edit the image, what toolbars, dialogs and filters are available in the program. You should remember that each raster graphic image is rectangular-shaped. We will now discuss how to work with image color models, how to make transformations, how to change its measurements, direction, resolution and other important settings which allow you to prepare the very basis of the image, i.e. the place where the image is drawn or edited. Color models The menu entry Image includes all the main commands for working with the image. We will first analyse the Mode entry; click on it to open a drop-down list of commands allowing you to work with color models:
271 RGB RGB is the default color model which is most popular among the editors of raster objects. Colors are preserved when editing the same object by several editors. Grayscale The model is best for editing old photos and creating old-photo type images or blackand-white images. Open the image and select ImageModeGrayscale to make the image grayscale. a) original image b) after ImageModeGrayscale command is applied When editing the image, you cannot use other colors but grey hues. If you select green for the Pencil tool , you will paint in light grey in the image. Note! When you return to RGB mode, you will not restore colors because the information on the color for each pixel is lost. You may select colors for <strong>tools</strong> and use them to supplement the image as well as to apply filters. Indexed This mode lets you set hues and the amount of colors mixed in the image independently. Select ImageModeIndexed command to open the dialog
