Building and Compiling opencv 3.1.0-dev to get an access for non free modules can be a headache for some people especially on Windows machine. Unlike Ubuntu, setting up opencv for Windows takes some time and requires a couple pf dependencies to be installed first before building and compiling. Th...

For this process to work, the original error/exit code should start with 0x8007 which generally is an indication it originated from a valid Win32 process. However, should no message appear, then it probably didn't originate from a Windows process and therefore, will need to be examined further ou...

pygame.display.set_mode(resolution=(0,0), flags=0, depth=0) # Returns a pygame.Surface representing the window on screen flags = pygame.FULLSCREEN | pygame.OPENGL # Flags can be combined using the "|" (bitwise OR or "pipe") character. parameterexplainationresolutiona pai...

If you want to have other colours as the background, then name a new variable such as red = (255,0,0) and change the display.fill(black) to display.fill(red). You can create colours by storing them in a variable and checking their RGB values from the internet.

plt.close() # closes the current active figure plt.close(fig) # closes the figure with handle 'fig' plt.close(num) # closes the figure number 'num' plt.close(name) # closes the figure with the label 'name' plt.close('all') # closes all figures

When Rust programs reach a state where a critical error has occurred, the panic! macro can be called to exit quickly (often compared, but subtly different, to an exception in other languages). Proper error handling should involve Result types, though this section will only discuss panic! and its con...

In Processing, drawing shapes is key to the program. Otherwise, nothing would appear on the screen. This section will tell you how basic shapes are drawn. line(float x1, float y1, float x2, float y2) line(float x1, float y1, float z1, float x2, float y2, float z2) ellipse(float x, float y, f...
