The way they do this is by editing the d3d/opengl DLL at the process memory level, like injecting assembly jumps. I know this because their method was causing my mod to crash, and … Read more
The pyplot.scatter() function was tailor made for this reason: import matplotlib.pyplot as plt im = plt.imread(image_name) implot = plt.imshow(im) # put a blue dot at (10, 20) plt.scatter([10], [20]) # put a red dot, size 40, at 2 locations: plt.scatter(x=[30, 40], y=[50, 60], c=”r”, s=40) plt.show() See the documentation for more info.
Ordinarily, “Swing programs should override paintComponent() instead of overriding paint(),” as mentioned in Painting in AWT and Swing: The Paint Methods. Based on ScrollPanePaint, which draws below the scrolling content, the following example overrides paint() to draw above the scrolling content. import java.awt.*; import javax.swing.*; /** * @see https://stackoverflow.com/a/10097538/230513 * @see https://stackoverflow.com/a/2846497/230513 * @see https://stackoverflow.com/a/3518047/230513 … Read more

If you just want to freeze the map view at the overlay, you could set the map view’s region to the overlay’s bounds and set scrollEnabled and zoomEnabled to NO. But that won’t let the user scroll or zoom inside the overlay’s bounds. There aren’t built-in ways to restrict the map view to the overlay’s … Read more
