Rect1.bottom=rect2.top), the two meet exactly on the screen but do not ![]() If one Rect's bottom border is another Rect's top border (i.e., The area covered by a Rect does not include the right- and bottom-most edge Most pythonĬontainers can be searched for collisions against a single Rect. There are several collision tests between other rectangles. Programmed to have negative values, but these are considered illegal Rects The coordinates for Rect objects are all integers. A Rect with a 0 size will not collide when using collisionĭetection methods (e.g. ![]() Some methods return a Rect with 0 size to represent an invalid If a Rect has a nonzero width or height, it will return True for a ![]() Some attributes are integers and others are pairs of integers. center = ( 20, 30 )Īssigning to size, width or height changes the dimensions of the rectangle Īll other assignments move the rectangle without resizing it. If the user presses ESC then close the image windowĪnd that’s pretty much it.Rect1.Now to improve the code, we want to do the following adjustments to it: Now we should be able to run the code python3 image_gimmick.py and should display an image as long as flower.jpeg file is available in the python code path. We can save the code in a file, let’s call it image_gimmick.py. Time.sleep(25) # wait for 25 seconds before image disappear Screen.blit(img, img_frame) # writing the image and the frame to the buffer Screen.fill(black) # filling the screen initially with black Img_frame = img.get_rect() # preparing the image frame Img = ("flower.jpeg") # loading the image in the current directory Screen = _mode(size) # set the display size Size = (().current_w, ().current_h) # putting display info in a tupleīlack = 0, 0, 0 # black color as the background color to fill the rest of the display To install pip3 on Debian based distributions we run apt install as follows, We avoid using Python 2.7 as it is obsolete. The very first step is to ensure we have the environment ready. In the following section I show you how to do that. The objective was given an image path and be able to view it in framebuffer. I started with the easiest one which is an image viewer. The last thing left was to define an app to rewrite. It’s the best option out there even though its main purpose is for game development. This way, the apps I write can also work with X11 without any issue. Of course, the first step was to find a library that supports framebuffer. I wanted to have fun and enjoy writing some code. Even though I love C by my heart, I didn’t want to create misery for myself. And if needed debug my own code is always better :-).Īdditionally, I didn’t want to write my programs with C. So I decided to start writing those that are easy. Because the hassle of setting them up is too much. However, sometimes I want to avoid using third-party framebuffer applications. BackgroundĪ part of my framebuffer journey is to replace some of the X11 applications with the framebuffer counterparts. In this article, I show you how to draw an image in Pinebook framebuffer with Pygame library using Python. This is less resource intensive and especially useful for ARM powered devices. The reason is I can manipulate the display directly without going through X11. Part of my tinkering with my Pinebook is to play around with framebuffer.
