Edit a bitmap with another image-editing application
1. In the Library panel, right-click (Windows) or Control-click (Macintosh) the bitmap’s icon, and select Edit With.
2. Select an image-editing application to open the bitmap file, and click OK.
3. Perform the desired modifications to the file in the image-editing application.
4. Save the file in the image-editing application.
The file is automatically updated in Flash Professional.
5. Return to Flash Professional to continue editing the document.
Break apart a bitmap and create a bitmap fill
Breaking apart a bitmap on the Stage separates the on-Stage image from its library item and converts it from a bitmap instance to a shape. When
you break apart a bitmap, you can modify the bitmap with the Flash Professional drawing and painting tools. Using the Magic Wand tool, you can
select areas of the bitmap that contain the same or similar colors.
To paint with a broken-apart bitmap, select the bitmap with the Eyedropper tool and apply the bitmap as a fill with the Paint Bucket tool or another
drawing tool.
Break a bitmap apart
1. Select a bitmap in the current scene.
2. Select Modify > Break Apart.
Change the fill of areas of a broken-apart bitmap
1. In the Tools Panel, select the Magic Wand tool. If the Magic Wand tool is not visible, click the Lasso Tool and select Magic Wand tool from
the pop-up menu. Set the following options in the Property Inspector:
For Threshold, enter a value between 1 and 200 to define how closely the color of adjacent pixels must match to be included in the
selection. A higher number includes a broader range of colors. If you enter 0, only pixels of the exact same color as the first pixel you
click are selected.
For Smoothing, select an option to define how much the edges of the selection are smoothed.
2. To select an area, click the bitmap. To add to the selection, continue clicking.
3. To fill the selected areas in the bitmap, select the fill to use from the Fill Color control.
4. To apply the new fill, select the Paint Bucket tool and click anywhere in the selected area.
Convert a bitmap to a vector graphic
The Trace Bitmap command converts a bitmap into a vector graphic with editable, discrete areas of color. You manipulate the image as a vector
graphic, and you can reduce the file size.
When you convert a bitmap to a vector graphic, the vector graphic is no longer linked to the bitmap symbol in the Library panel.
Note: If the imported bitmap contains complex shapes and many colors, the converted vector graphic might have a larger file size than the
original bitmap. To find a balance between file size and image quality, try a variety of settings in the Trace Bitmap dialog box.
You can also break apart a bitmap to modify the image with Flash Professional drawing and painting tools.
1. Select a bitmap in the current scene.
2. Select Modify > Bitmap > Trace Bitmap.
3. Enter a Color Threshold value.
When two pixels are compared, if the difference in the RGB color values is less than the color threshold, the two pixels are considered the
same color. As you increase the threshold value, you decrease the number of colors.
4. For Minimum Area, enter a value to set the number of surrounding pixels to consider when assigning a color to a pixel.
5. For Curve Fit, select an option to determine how smoothly outlines are drawn.
6. For Corner Threshold, select an option to determine whether sharp edges are retained or smoothed out.
To create a vector graphic that looks most like the original bitmap, enter the following values:
Color Threshold: 10
Minimum Area: 1 pixel
Curve Fit: Pixels
Corner Threshold: Many Corners
