Open a Terminal or command prompt window and cd to the folder where the exported PNGs are located. Step 4: Create a GIF file using ImageMagick Notice that Inkscape automatically numbers the patterns in increasing order. Inkscape will export 12 PNGs to the same folder where you saved the SVG file. Check the Batch export 12 selected objects box. This means that only the selected objects will be exported to PNG. Press Cmd + Shift + E ( Ctrl + Shift + E on Windows) to open the Export PNG Image dialogue box. Select all patterns except the original one. You will see the original pattern sitting under that clone. Select the pattern that sits the position of the original one and drag it to a side. When Inkscape creates tiled clones, it keeps the original object. You will see 12 copies of the pattern created with rotations applied in 30 degree increments. Set the angle field to 30 under Per column.
Before we set any transformation options to the clones, we will make sure all the values are set to defaults. A dialogue box will open with various option for creating clones of the pattern. Make sure the pattern is selected and go to Edit → Clone → Create Tiled Clones. For this, we need to create multiple copies of the pattern, with each one slightly rotated with respect to the previous one.
To create an illusion of motion, we will rotate the image in small steps.
Step 2: Create copies of the pattern to imitate motion I have included here an example SVG pattern to start, but you have the choice of using your own pattern. If you are beginning with vector art creation, there are a variety of tutorial available online. In this tutorial, we will start with a basic vector sketch in Inkscape and use that to create the animation. Step 1: Create the basic sketch in Inkscape This tutorial shows a relatively simple method of creating animated preloader GIFs using two popular open source softwares - Inkscape and Imagemagick. There are several ways of showing such an animation - CSS3, animated GIFs, Flash. The animation gives the viewer a sense that some process is happening in the background and fetching the data that they wish to see. Preloaders are animated images shown on a webpage while the main content is loading.
