Line 190: − + − ===== Cropping an image =====+ − Often, you want some part of a larger image to re-use in a different resource. GIMP allows you to select parts of an image - in different shapes or even using a freehand selection to select parts of an image. + − + − This is different from a screen shot where you can only grab an area that is in the shape of a rectangle. You can select parts of an image from Select Tools → Selection Tools → Free Select You can move your cursor on the image to outline the area you want to crop, this is free hand, not necessarily in the form of a rectangle. Then crop the image to your selection through Image → Crop to Selection (image 9). We have cropped the image to free select only the teacher and the student (see the dotted line in image 9). − − You can export this cropped image using File → Export as and export to an image format like .png or .jpeg. − − ===== Adding text to an image ===== − You may want to add a caption to an image and make that caption a part of the image itself. − Select Tools → Text. A text tool box appears. − − Place your cursor where you want to type your text. You can format the text (change font size, colour) through the Text tool box. − − In our image, we have added the text ‘Digital Storytelling, Health centre’ and selected the yellow colour for the text, since it will display better against a dark background (image 10). (Tip - the text should be in a colour contrasting with the background, for easier visibility). − − ===== Reducing the size of an image ===== − Sometimes image files can be heavy (compared to text only files). You can reduce the size of an image using GIMP. Select Image → Scale image (image 11). You can reduce the resolution in the form that opens. The more you reduce the resolution, the greater the reduction of file size. You should then over write the file, File → Overwrite <your file name>. GIMP will open a form asking for reduction in quality. You can reduce quality up to 30% without visible degradation in quality. − − − − {| class="wikitable" − |'''Student activity time''' - − You should use GIMP to work on your image OER that you have created. You should use the text input option to enter captions on your image OER. You can crop a part of an image which contains the message you want to convey. You should also try and reduce the size of your images. − − Creating a picture story − − You can create small picture stories by combining images which you have edited with the image editor with text, in a text editor. Picture stories can support basic language learning. You can create bi-lingual story books also, so that strength in one language can be used to acquire a second language. (See simple picture stories created by students). − − In your Kannada and English language source books, you have many stories and essays in the exercises. Try to convert these into picture stories/essays, by adding relevant images, which you have accessed/downloaded and edited, or created. − − Tip - You can put your ideas in a concept map first, before you write out your story. You should always prepare a concept map before every article or story you write. The concept map will help you write out all the ideas you want to cover, and help you place them in relationship to one another. Since you can create or move the nodes easily in a digital concept map, this will help you think in an iterative manner to revise and refine your ideas well before you actually write the story or article. − − References: [[Learn GIMP]] +
