coordinate system

Functions

  • measure of the x and y coordinate of a point in an cartesian coordinate system

Description

With the coordinate system, you can measure the the coordinates of a point in this coordinate system. The Point is the mouse position. It can be a cartesian or an affine coordinate system.
Move the blue point to move the complete coordinate system.
You can change the directions of the axes by moving the green points. The origin keeps unchanged.

Functions in the popup menu

Track mouse the measured lines are always drawn
Attach to window when the measure instrument is moved, the window below will be detected and the instrument attached to this window. If this window is moved in a further operation, the measure instrument is moved synchron to this window. This mode is active, as long as the menu item Attach to window is checkd and the window is visible. If you minimize this window or close the attached application, the mode is deactivated, too.
Modify - Set to origin state the measure instrument is moved to a defined start position
Modify - Rotate 180° the measure instrument is rotated by 180°
Modify - Rotate 90° clockwise the measure instrument is rotated by 90° clockwise
Modify - Rotate 90° anticlockwise the measure instrument is rotated by 90° anticlockwise

Supported function keys

<Ctrl><Alt><C> copy the measured values to the clipboard
<Ctrl><Alt><cursor left> move the measure instrument one pixel to the left
<Ctrl><Alt><cursor right> move the measure instrument one pixel to the right
<Ctrl><Alt><cursor up> move the measure instrument one pixel up
<Ctrl><Alt><cursor down> move the measure instrument one pixel down
Have a look at the function key help page for more details about the functions keys and how you can configure them.
