Block Icons
You can also supply images to use as icons for a custom block using the macro metadata element <icon> in <block>.
If you supply a custom icon, you must provide two images of the correct size for the Wires Blocks Menu and for the canvas:
Custom block icon images can be in any format that is web accessible. The size of the image for each icon is:
menu icon = a maximum of 14 pixels square, with no border.
canvas icon = exactly 40 pixels square, including a 2-3 pixel border. The built-in
Wires blocks use an icon that is 38px square with a 2px drop shadow. The border is 2px wide in #818181 grey.
Tip: | Canvas icons should always have a border to ensure that input and output ports for the block render well and are clearly associated with that block. |
As with all icons, the image should be graphic and easy to distinguish from the icons for other blocks.
The URL to icons can be absolute when the image is hosted in a web server or application server that is accessible to the Business Analytics Server.
You can use relative URLs for icons if a Business Analytics administrator uploads the images. Use a URL in the form /mashzone/files/path/filename where path/filename is the name assigned to the image in Business Analytics.
