|
|
Here is an example of running the program:
|
|
|
|
How many sample labels do you want? 2
|
|
Enter the dimensions of the label
|
|
Height: 3.25
|
|
Width: 3.25
|
|
Enter the dimensions of the label
|
|
Height: 2.15
|
|
Width: 4.55
|
|
|
|
|
|
Here are the characteristics of your labels
|
|
Label No. 0
|
|
Height = 3.25
|
|
Width = 3.25
|
|
Perimeter = 12.5625
|
|
Area = 10.5625
|
|
|
|
Label No. 1
|
|
Height = 2.15
|
|
Width = 4.55
|
|
Perimeter = 11.7825
|
|
Area = 9.7825
