SD/CD Series Card Printers OpenCard Data Format Guide 39
Defining Image Element Layers
Images are supported as static only. This means that data stream items may not be used in
conjunction with images.
Images are printed bottom-to-top in the order that they appear in the card format. For example,
if the full card tree graphic is followed by the Datacard logo, the tree graphic prints on the
bottom with the Datacard logo printed on top.
There is no limit to the quantity of images that can be rendered to a personalization operation.
However, card production throughput may be adversely affected by use of increasing quantities
of images, as it takes time to read and process images in the printer.
Defining Image ID Names
For image IDs, choose any name that is useful to the card format, other than the OpenCard data
naming pattern “LINEn”, which is reserved for dynamic text data.
datacard:positionReference Attribute
Valid values are:
• topLeft (SVG standard compatible option and default)
• bottomLeft
If “topLeft” is specified then the image y attribute will be a measure from the top edge of a card
to the top edge of the image.
If “bottomLeft” is specified then the image ‘y’ attribute will be a measure from the bottom edge
of a card to the bottom edge of the image.
