Image Settings Dialog

You use the Image Settings dialog to configure the default format of images that —

• Are posted to the test log by the Log Message and Post Screenshot keyword testing operations.

• Are posted to the test log by the Log.Message, Log.Picture, Log.Error, Log.Warning and Log.Event scripting methods.

• Are saved to the Stores | Regions collection by region checkpoints, via the Regions.AddPicture method or when you add images to the collection manually.

To call the dialog, click Configure in the Images section of the Project Properties - General Options or Default Project Properties - General Options dialog.

In the dialog, the following options are available:

• Image format - The format of the saved images. The following formats are supported —

  • BMP

  • JPEG

  • PNG

  • TIFF

  • GIF

  • ICO

  You can use custom image adapters to get support for additional image formats.

Depending on the image format you choose, the following image format settings become available:

• BMP Format

  • Image color palette - The color depth for image files, which can be —

    • 4 bits (16 colors)

    • 8 bits (256 colors)

    • 16 bits (65536 colors)

    • 24 bits (16777216 colors)

    • 32 bits (16777216 colors)

    • Native (no transformation)

• JPEG Format

  • Compression quality - The number that determines the degree of loss in the compression process. The minimum, 1, yields the smallest files; the maximum, 100, yields the largest files.

  • Gray Scale - Specifies whether saved images are in color or in grayscale.

• PNG Format

  • Compression level - Specifies the compression level (0 to 9) with the default value of 4. The minimum, 0, means that the file is uncompressed and has the largest size. Upper compression levels require much time for compressing an image, but the resulting file will be smaller. The maximum, 9, means the slowest compression and the best compressed file size.

  • Interlaced - Specifies whether saved images are interlaced.

• TIFF Format

  • Compression type - The type of compression used to save images. Possible values are —

    • No compression

    If you use the CCITT Group 3 or CCITT Group 4 compression, TIFF images will be monochrome.
