Visual Filters and Transitions Reference

This topic documents a feature of Visual Filters and Transitions, which is deprecated as of Windows Internet Explorer 9.

As of Microsoft Internet Explorer 4.0, you can apply multimedia-style effects to your Web pages using visual filters and transitions. You can apply visual filters and transitions to standard HTML controls, such as text containers, images, and other windowless objects. Transitions are time-varying filters that create a transition from one visual state to another. By combining filters and transitions with basic scripting, you can create visually engaging and interactive documents.

Internet Explorer 5.5 and later supports a rich variety of optimized filters. Click the following button to see a demonstration of many of these filters and how to use them.

Code example: http://samples.msdn.microsoft.com/workshop/samples/author/dhtml/DXTidemo/DXTidemo.htm

The links in the following sections provide access to the object model exposed by the visual filters and transitions.

Procedural Surfaces Reference

Procedural surfaces are colored surfaces that display between the content of an object and the object's background. Procedural surfaces define each pixel's RGB color and alpha values dynamically. Only the procedure used to compute the surface is stored in memory. The content of an object with a procedural surface applied is not affected by the procedural surface.

Procedural Surfaces

AlphaImageLoader

Displays an image within the boundaries of the object and between the object background and content, with options to clip or resize the image. When loading a Portable Network Graphics (PNG) image, tranparency from zero to 100 percent is supported.

Gradient

Displays a color gradient between the object's background and content.

Static Filters Reference

Though all filters and transitions are technically filters, the following filters statically change the way the content of an object displays. The Compositor filter is implemented as a transition, but gives only a static output.

Static Filters

Alpha

Adjusts the opacity of the content of the object.

BasicImage

Adjusts the color processing, image rotation, or opacity of the content of the object.

Blur

Blurs the content of the object so that it appears out of focus.

Chroma

Displays a specific color of the content of the object as transparent.

Compositor

Displays new content of the object as a logical color combination of the new and original content. The color and alpha values of each version of the content are evaluated to determine the final color on the output image.

DropShadow

Creates a solid silhouette of the content of the object, offset in the specified direction. This creates the illusion that the content is floating and casting a shadow.

Emboss

Displays the content of the object as an embossed texture using grayscale values.

Engrave

Displays the content of the object as an engraved texture using grayscale values.

Glow

Adds radiance around the outside edges of the content of the object so that it appears to glow.

ICMFilter

Converts the color content of the object based on an Image Color Management (ICM) profile. This enables improved display of specific content, or simulated display for hardware devices, such as printers or monitors.

Light

Creates the effect of a light shining on the content of the object.

MaskFilter

Displays transparent pixels of the object content as a color mask, and makes the nontransparent pixels transparent.

Matrix

Resizes, rotates, or reverses the content of the object using matrix transformation.

MotionBlur

Causes the content of the object to appear to be in motion.

Shadow

Creates a solid silhouette of the content of the object, offset in the specified direction. This creates the illusion of a shadow.

Wave

Performs a sine wave distortion of the content of the object along the vertical axis.

Transitions Reference

Transitions are filters that reveal new content of an object with a particular visual effect. Use the apply and play methods to initiate the visual effect.

Transitions

Barn

Reveals new content of the object with a motion that resembles doors opening or closing.

Blinds

Reveals new content of the object with a motion that appears to open or close blinds.

CheckerBoard

Reveals new content of the object by uncovering squares placed like a checkerboard over the original content.

Fade

Reveals new content of the object by fading out the original content.

GradientWipe

Reveals new content of the object by passing a gradient band over the original content.

Inset

Reveals new content of the object diagonally.

Iris

Reveals new content of the object with an iris effect, similar to the opening of a camera aperture.

Pixelate

Displays the content of the object as squares that take on the average color value of the pixels they replace. This filtered display can be used as a transition.

RadialWipe

Reveals new content of the object with a radial wipe, like a windshield-wiper blade.

RandomBars

Reveals new content of the object by exposing random lines of pixels.

RandomDissolve

Reveals new content of the object by exposing random pixels.

Slide

Reveals new content of the object by sliding sections of the image into place.

Spiral

Reveals new content of the object with a spiral motion.

Stretch

Reveals new content of the object with a stretching motion to cover the original content. One option resembles a cube rotating from one face to another.

Strips

Reveals new content of the object by moving successive strips into place, like a diagonal saw blade passing across the original content.

Wheel

Reveals new content of the object with a rotating motion, like spokes of a wheel covering the original content.

Zigzag

Reveals new content of the object with a forward and back motion that moves down the object.
