Algorithm (Workflow)
This function, ispatch, determines if a given graphics object handle in MATLAB is a patch object. It is part of the SolidGeometry library and was introduced by Tim Lueth.
Input Parameters
- h: This is the graphics object handle. If no handle is provided, the function defaults to using the current graphics object, which is obtained using
gco.
Output Results
- b: This is a boolean value. It returns
true if the object is a patch, and false otherwise.
Algorithm Steps
- Initialize
h with the current graphics object using gco.
- Check if there are any input arguments. If there is at least one argument, set
h to the first argument provided.
- Use the
get function to retrieve the 'Type' property of the graphics object handle h.
- Compare the 'Type' property with the string 'patch' using
strcmp.
- Return the result of the comparison as the output
b.
Example Usage
The function can be used as follows:
SGfigure;
h = [CPLplot(PLcircle(20)); SGplotalpha(SGbox, 'g')];
ispatch(h);
This example creates a figure and plots a circle and a box. The ispatch function is then used to check if the plotted objects are patches.
