Because of Xara X, this relatively sophisticated animated gif was fairly easy to create. It shows how Xara X enables you to take any graphic you've created and go back at a later date and turn it into a animated gif. This one didn't start out as an animation - I created the porthole graphic for this page to demonstrate Xara X's ability to apply transparency effects to vector illustrations. To create sailboat movement that wasn't excessively fast or jumpy, I had to balance the number of frames with how long they get displayed. Xara X gives you the tools necessary to achieve that balance easily. This animation has 20 frames - which is quite a few. All the frames except the first are displayed for 1/5th of a second. The first frame displays for two seconds - it doesn't have the sailboat in it so it gives a bit of a pause before the boat sails past again. The animation was set to loop endlessly. I think the pause adds a touch of sophistication that you don't usually see in animated gifs. With 20 frames I had to be very careful not to end up with an unacceptably large file size. To keep it down to its 20k file size I had to adjust the number of colors used. The more colors you use, the better looking the animation - but also the larger the file size. Xara X makes it easy to try various possibilities. I find its ability to provide a browser preview, complete with detailed analysis, particularly useful. The analysis tells me about the image size, its color pallet and how long it will take to download at various modem speeds. Most animated gifs
are created using bitmap-based graphics programs. In those programs if
you want to change your animation - it really is like starting over. By
comparison Xara X is a quantum leap forward in flexibility. Everything
in the Xara X animation remains fully editable - and it can be edited
with ease. Make the sailboat blue? - No problem! Make the sailboat go
the other direction? - No problem! Change the color of the sunset and
make the brass less shiny? - Read my lips! No problem!
