colorPalette Property

A set of custom color names.

Details

Type: List of CustomColor Structures
Since: reserved
Required: No
Display Name: Color palette
JavaScript Type:
Default Value: None
Inherited: No
Runtime Settable: No
Property Sheet Visibility: Hidden
Property Sheet Group: Top

Description

The developer can define a set of custom color names as part of the design. The developer can then reference these names within properties. Defining the colors in the palette helps the developer achieve a consistent look throughout the report, and allows colors to be refined by changing just one place.

Every custom color has three parts: a display name, an internal name and an RGB value. The display name is what the developer sees. If the palette will be used by people in different countries, then the display name can be externalized and translated. The internal name identifies the color within the design and in the XML design file. The internal name cannot be localized. Finally, the RGB value gives the actual color.

Description

Reports frequently have deployment-specific dependencies. For example, developers often use a test database during development, but target a production database once the report is deployed. Or, an OEM may use a different company name in report titles for each of their customers. BIRT provides configuration variables to support such cases. A configuration variable is a name/value pair.

See the helpGuide and the description properties for a way to provide information for the users of the report.

images Property

A list of images embedded in this report.

Details

Type: List of EmbeddedImage Structures
Since: 1.0
Required: No
Display Name: Images
JavaScript Type:
Default Value: None
Inherited: No
Runtime Settable: No
Property Sheet Visibility: Hidden
Property Sheet Group: Top

Description

A design often uses images. Most images in a report will be accessed via a URL, or a file deployed externally to the report. However, some reports may want to embed an image directly into the report design. Embedded images are especially helpful if a report design is generated in a custom application and sent to the server for one-time execution.

Images have a name. The name allows an image item to reference the embedded image. Scripts can use the image name to retrieve the image from the images array:

var img = report.design.images["MyImage"]
