image
RasterImage object that references the image to be searched for registration mark.
type
Value that specifies the type of registration mark for which to look. Currently, only one registration mark is defined (T-shape). See the Comments for more information. More shapes will be added in the future.
minScale
Minimum scaling factor of mark to be detected. This is a percentage. It must not exceed maxScale, or an error will be returned. This parameter accepts only positive values.
maxScale
Maximum scaling factor of mark to be detected. This is a percentage. It must not be lower than minScale, or an error will be returned. This parameter accepts only positive values.
width
The width of the registration mark (in pixels). This parameter accepts only positive values.
height
The height of the registration mark (in pixels). This parameter accepts only positive values.
Boolean value indicating weather that specific object is registration mark or not.
Currently, there is only one type defined, a T-shaped figure as shown in the following figure. This type is a "T" rotated by 90 degrees counter clockwise. The P4 point must be on the center point of Line P1P2 (that is, the distance from P1 to P4 equals the distance from P2 to P4). The line width should be greater than 2 pixels(preferably 3 pixels). There are no conditions on line lengths since you provide the values for width, height, maxScale, and minScale.
Do not use this command to search for registration marks inside the image. Use SearchRegistrationMarksCommand instead.
For more information, refer to Detecting Registration Marks.
This example determines if the object is a registration mark.
