Tip : Select All Horizontal and Vertical Lines on In Pictures

There are times we need to select all horizontal or vertical lines in an image. It is not easy and can be tedious, especially if we work on the rather complex picture. We can use QSELECT to do this job quickly!

How do you use? Easy. Vertical lines means the lines have the same X value, while the horizontal line have the same values ​​of Y!

Take a look at QSELECT. Change the object type to the line, the properties to the delta X (or Y delta, depending on the type of line you want to choose), and change the value to 0. Click OK, and you're done!


Note: 

You can perform further filtering. You can just select all the vertical lines in Layer A, or a horizontal line that has a red color and length of 100 units, and so on. You know how right?
