Pyglet CornerPin
This is a little utility that adds corner pin transforms to a pyglet window.
Installation
pip install pyglet-cornerpin
Usage
Create instance for a window, and register the event handlers for dragging the pins. A on_key_release is also registered to handle keyboard controls to move the pins.
pins = PygletCornerPin(window)
# event handlers for dragging:
window.push_handlers(pins)
Then you can draw the pins in your on_draw() event.
@window.event
def on_draw():
window.clear()
...
# draw corner pins
pins.draw()
Optionally you can provide initial positions for the pins.
corners = [
(0, 0), # Bottom left
(window.width), # Bottom right
(0, window.height), # Top left
(window.width, window.height), # Top right
]
pins = PygletCornerPin(window, corners)
Moreover, you don't need to pin the window corners, but can pin from any four arbitrary points, by providing source_points.
Run pattern.py in the examples folder for a demo.
To use the keyboard, select a pin with number keys 1-4, the use the arrow keys (optionally with ctrl/shift modifier) to move the handle.
