CLabels:SetParams
The SetParams method changes the properties for labels drawn on an image. Label properties are initialized to reasonable values by the class. The purpose of this method is to change the properties by setting values in the LabelParams table. See the Mira User's Guide for more information under the main topic Measuring Images.
bSuccess = CLabels:SetParams( LabelParams_table) |
where LabelParams_table is a table of type LabelParams containing properties to change.
On success, true is returned.
Suppose an image window exists on the Mira screen and you have a collection of object coordinates you wish to label on the image. The script below changes the marker size, drawing color, and line thickness from default values. Note that your table does not need to be named Params. Also, the values of x, y, and str do not need to be explicitly defined and could be included as parameters in the call to Add.
