![]() ![]() Similar approaches can be used for blur and color transforms.Īnother option is to create a sprite sheet animation of the filter effect and use that in your ad instead. For example, to transition an image from grayscale to color, you could simply duplicate the image, apply a grayscale color adjustment to the top copy, and fade down its alpha over the color copy. It is possible to animate content with a filter by re-rendering the filter each tick (or frame) viamyDisplayObject.updateCache(), but in almost all cases it is better to consider alternative approaches. This is an intentional limitation, because updating filters is very expensive, and it would be very easy to unintentionally create content with very poor performance. ![]() Similarly, the filter cannot be animated on the timeline. This bitmap caching "freezes" the movieclip on its first frame, which stops it from animating. These effects work by manipulating pixel data, can be quite expensive to render, and require bitmap caching to be enabled to work (this is done automatically when you apply these filters in Flash Pro). Filter Effectsīlurs, color transforms (excluding alpha), and color adjustments are treated as filters in EaselJS. They render reasonably fast on desktop, but can cause performance issues on mobile, and can be applied to animated content.Īt this time, shadow effects cannot be animated on the timeline, though this is primarily an authoring limitation that may be removed in the future. Shadow Effectsĭrop shadows and glows (which are essentially shadows with no offset) are rendered in EaselJS using canvas's built in shadow features. ![]() All effects are expensive to render, particularly on mobile devices, and should be tested thoroughly. These effects fall into one of two categories: shadow effects, and filter effects. Flash Pro CC supports most filters and color effects. I am using the value 1.2em a lot to define the height and the offset of the shadows, making it an ideal candidate for a CSS custom property (which we’re calling -h). Adding a drop shadow to a text illustrator using Adobe After Effects, below or behind the text during the creation of a handwritten animated text can help the animation look more professional. This is the main trick that that makes all of the examples in this article work. Animators frequently use the drop shadow to create the 3D effect in the video on desktop using Adobe After Effects. If we hide the overflow, then the duplicated text is out of view and the movement makes it appear as though the actual text is being replaced by other text. We have two text layers that we move on hover. If you Altclick the icon, the selected filter is enabled, and all others filters in the list are disabled. To toggle the enable state of the other filters in the list, Altclick (Windows) or Option-click (Macintosh) the enable icon in the Filter list. What we’re doing is less of a “classic” shadow than it is a simple way to duplicate the text. Click the X button next to the filter name to enable a Filter. That’s why I was able to claim in the introduction that there are no shadows in here. That means there’s no blur radius, making for a sharp, crisp shadow that effectively produces a copy of the text with the specified color. After that, I am using text-shadow to create two shadows where I am defining only two length values for each one. The first thing to notice is that I am making the color of the actual text transparent (using #0000) in order to hide it.
