Export to a GIF or PNG file

You can export your content to .gif and .png formats, which are useful file formats for incorporating into a mobile media file or for viewing your content on third-party handhelds or Internet browsers.
  1. Perform one of the following actions:
    • On the File menu, click Export > GIF.
    • On the File menu, click Export > PNG.
  2. In the Information section, change the following settings:

    Field

    Description

    Show Preview

    Select this option to display a preview pane on the right side of the dialog box. You can preview changes before you update the image.

    Update

    View information on the file properties after making changes to other properties on the dialog box.

    If you select Show Preview, you can view your changes when you click the Update button.

    Live Update

    Select this check box to update the information automatically.

    Note: If your computer has a slow processor, you might experience slower processing when using Live Update.

  3. In the Generic Options section, select any of the following check boxes.

    Option

    Description

    Override Background Color

    Select this check box to use a different background color than that set in the BlackBerry® Composer. Click the color swatch and click a color.

    Use Temporary Image Cache

    Select this check box for smaller content files to improve performance when previewing different export settings or re-exporting a BlackBerry Composer file that has not been changed.

    Interlace

    When you select this check box, images first appear blurry and become sharper as they are downloaded. When Interlace is not selected, images appear gradually, top to bottom, as they download.

    With still GIF images, interlacing allows users with slow modem connections to click past an image they are not interested in viewing without having to download the whole thing. Do not use Interlacing for animated GIFs.

    Note: With larger images, the cache can consume a lot of memory and, depending on how much RAM is available, might need to be turned off.

  4. Depending on the type of export, select the applicable options.

    Field

    Description

    Filter

    • None compresses the image without a filter. This option is recommended for indexed-color and Bitmap-mode images.
    • Sub optimizes the compression of images with even horizontal patterns or blends.
    • Up optimizes the compression of images with even vertical patterns.
    • Average optimizes the compression of low-level noise by averaging the color values of adjacent pixels.
    • Path optimizes the compression of low-level noise by reassigning adjacent color values.
    • All applies the filter—Sub, Up, Average, or Path—best-suited for the image. Select All if you are unsure of which filter to use.

    Compression

    Specifies a method to reduce file size.

  5. In the Color Reduction section, set any of the following color reduction options.

    Option

    Description

    Color Mode

    Select the mode to use.

    Palette

    This drop-down list is available when you select Palette from the Color Mode drop-down list. Determine which set of 256 (or fewer) colors is used in the exported animation:

    • Adaptive automatically selects a set of colors that best approximate the original.
    • Web-safe uses a standard set of 216 colors. Web-safe colors are recommended for BlackBerry devices.

    Dithering

    Dithering might improve image quality. Selecting this option increases your file size.

    Dithering Noise

    From the Dithering Noise drop-down list, select a value.

  6. To name and save the current export settings for later use or to load a previously saved group of setting, select the Save current settings when closing check box.
  7. Click OK.
