Creating Special Effects with Graphics
and Gradients
XPXPObjectives• Import bitmap graphics into a document• Change a bitmap graphic’s properties• Convert a bitmap graphic to a vector graphic• Create a fade effect animation using bitmaps• Learn about gradients
New Perspectives on Adobe Flash CS4 2
XPXPObjectives• Create and save a new gradient• Use and transform a gradient• Explore the Flash publish settings• Publish a Flash movie• Create a publish profile• Export a Flash graphic• Insert a Flash movie into an existing Web page

XPXPWorking with Bitmaps• Bitmaps appear more natural than vector
graphics• A photograph is an example of a bitmap graphic• Bitmaps are stored as a matrix of pixels• Bitmaps must be imported into a Flash document• A bitmap may be converted into a vector graphic
New Perspectives on Adobe Flash CS4 4
XPXPImporting a Bitmap• On the Application bar, click File, point to Import,
and then click Import to Stage or Import to Library
• In the Import or Import to Library dialog box, navigate to the location of the bitmap file, and then select the bitmap file in the file list
• Click the Open button

XPXPSetting a Bitmap’s Properties• Bitmap Properties dialog box• Properties: name, smoothing, compression, and quality
settings• Compression: Lossless (PNG/GIF), Photo (JPEG)• JPEG Quality range: 0 to 100• Setting bitmap properties in the banner– Apply additional compression to reduce file size– Loss in quality is not discernible due to small bitmap
size

XPXPAnimating Bitmaps• Instances of bitmaps can be animated – Instance on Stage must first be converted to a symbol
• Types of motion tweens applied to bitmaps:– Moving, rotation, scaling, and fading
• Fade effects are created by changing alpha amount• Alpha amounts controls image – 0% makes the object completely transparent– 100% makes the object completely opaque

XPXPConverting a Bitmap to a Vector Graphic• Reasons to convert a bitmap to a vector graphic:– Bitmap is geometric in nature– Visual effects will be applied to the graphic
• Converting a bitmap to a vector graphic: – Go to Modify Bitmap Trace Bitmap– Specify values and set options– Caveat: some color and quality lost in conversion

XPXPUsing Gradients• Gradient: gradual blend or transition of colors• Gradients enhance the appearance of objects• Add gradients as fills the way solid colors are added• Linear gradient – Blends colors from one point to another in a straight
line• Radial gradient – Blends colors from a point outwards in a circular
pattern

XPXPGradient Examples
New Perspectives on Adobe Flash CS4 16
XPXPCreating, Editing, and Saving a Gradient• To create a gradient, open the Color panel, click the
Type button, and then click Linear or Radial (or click a preset gradient in the color palette or the Swatches panel)
• To edit a gradient, add or delete a color pointer• To specify a color for a color pointer, select the color
pointer, and then enter the color’s RGB values, hexadecimal value, or click the color picker in the Color panel
• To add a color pointer, click a spot on the gradient definition bar
New Perspectives on Adobe Flash CS4 17
XPXPCreating, Editing, and Saving a Gradient• To remove a color pointer, drag it down, away from the
gradient definition bar• To reposition a color pointer, drag it to the left or right
on the gradient definition bar• To save a gradient with the current document, click the
Color panel options menu, and then click Add Swatch

XPXPApplying a Gradient Fill• Follow the same process for applying a solid fill• Two options for applying gradient to single object:– Select gradient fill color and draw object on Stage– Use Paint Bucket tool for object already on the Stage
• Lock Fill modifier – Paints one gradient across several objects on the
Stage

XPXPFilling Text with a Gradient• You can apply a gradient fill to text• Convert the text to a fill with the Break Apart command– Use command one time for text blocks consisting of
one letter– Use command two times for text blocks consisting of
multiple letters

XPXPTransforming Gradient Fills• Gradient Transform tool: modifies a gradient fill – Selected object with linear gradient has a bounding
box – Selected object with radial gradient has a bounding
circle• Modifiable gradient properties: center, size, direction • How to transform a gradient: – Drag the handles in the bounding box or circle
surrounding the center point

XPXPComparing Publishing Options• FLA format: native file format for Flash documents• SWF file: plays in Flash Player window or browser• Default – (HTML): creates an SWF and HTML file• Static publishing formats: JPEG, GIF, and PNG• Projector file: stand-alone file with .exe extension – Has the Flash Player incorporated into it – Plays the movie in its own window
• Publish Settings dialog box– Used to specify how FLA documents are published
New Perspectives on Adobe Flash CS4 28
XPXPPublish Settings• Default options: Flash (.swf) and HTML (.html)– Each file type has an options tab
• Select check box for different formats– New options tab appears for each new type selected– Example: JPEG tab appears if JPEG Image (.jpg)
chosen• New publishing profiles may be saved for later use• New banner will be published as an SWF file– Rationale: banner will be added to an existing Web
page

XPXPExporting a Flash Document as an Image• Two common image file formats used in Web pages:– JPEG format: best for images that include many colors– GIF format: best for images with fewer colors
• Some export formats in Flash: JPEG, GIF, PNG• Two ways to export images in Flash:– Select options in Publish Settings dialog box– Use the Export Image command
• Logo will be exported as a GIF image

XPXPAdding Flash Graphics to a Web Page• Requirement for using Flash graphics in a Web page:– Graphic file must be incorporated into the page’s
HTML• One simple way to incorporate graphics in HTML:– Publish a movie with the HTML format option
selected• Adding the SWF file to an existing Web page: – Actual Web page must edited – Some editing tools: Adobe Dreamweaver, Notepad
• Use Notepad to edit page displaying banner and logo
