  2. Objectives • In this lesson, you will learn: • To use filters to achieve special effects. • To combine filters to achieve an even greater variety of special effects. • To be able to create animated visual transitions between Web pages. • To be able to modify filters dynamically, using DHTML.

  3. 15.1  Introduction • Filters • Cause changes that are persistent • Transitions • Temporary • Allow transfer from one page to another with pleasant visual effect • For example, random dissolve

  4. 15.2  Flip Filters: flipv and fliph • flipv and fliph filters mirror text or images vertically and horizontally, respectively

  7. fliph filter applied No filters applied Both and fliph flipv flipv filter applied filters applied

  8. 15.3  Transparency with the chroma Filter • chroma filter applies transparency effects dynamically • Without using a graphics editor to hard-code transparency into the image • onchange • Fires when the value of a form changes

  12. 15.4  Creating Image masks • Background is a solid color • Foreground is transparent to the image or color behind it

  15. 15.5  Miscellaneous Image Filters: invert, gray and xray • invert filter • Negative image effect • Dark areas become light and light areas become dark • gray filter • Grayscale image effect • All color is stripped from the image, only brightness data remains • xray filter • X-ray effect • Inversion of the grayscale effect

  18. 15.6  Adding shadows to Text • shadow filter • Showing effect • Three-dimensional appearance

  21. 15.7  Creating Gradients with alpha • alpha filter • Gradient effect • Gradual progression from starting color to target color • style • Uniform opacity (value 0) • Linear gradient (value 1) • Circular gradient (value 2) • Rectangular gradient (value 3)

  25. 15.8  Making Text glow • glow filter adds an aura of color around text

  30. 15.9  Creating Motion with blur • blur filter creates an illusion of motion by blurring text or images in a certain direction • Add • Adds a copy of the original image over the blurred image • Direction • Determines in which direction the blur filter is applied • strength • Determines how strong the blurring effect is

  36. 15.10  Using the wave Filter • wave filter allows user to apply sine-wave distortions to text and images on Web pages • add • Adds a copy of the text or image underneath the filtered effect • freq • Determines the frequency of the wave applied • phase • Indicates the phase shift of the wave

  39. 15.11  Advanced Filters: dropShadow and light • dropShadow • Creates a blacked-out version of the image, and places it behind the image • offx and offy properties • Determined by how many pixels the drop shadow is offset • color property • Specifies the color of the drop shadow • light filters • Most powerful and advanced filter in Internet Explorer 6.0 • Allows simulation of a light source shining on Web page • All parameters and methods are set by scripting • addPoint • Adds a point light source
