EEHPH was designed from the top to be speedy on low-powered computers. This graph shows how long it took to open a 1080p image on an AMD A9-9420, a fairly slow processor. Built-in image transformations Save images resized, maintaining ratio, flip and rotate images in the program: Easy to open images Opening images is as easy as with any other image viewer. Right Click and Open with or set as the default image viewer for opening with a single click. Open Source Want to modify the code, fix bugs or help development? EEHPH is fully open source with a GNU license. Source code is maint

So you have just compiled your Windows Python application. You want to make an installer for your users to easily get the application onto their PCs. You have tried using cx_Freeze's bdist_msi option but it is not advanced enough. Perhaps you want to run a script on installation or on uninstall, or want an easy way of adding an icon to the user's desktop. Now the easiest tool to use is inno. In this post we're going to take a look at how to use inno's setup wizard to package your application, as well as editing the script file. So the first thing you are going to want to do is to jump onto  inno's download page  and download inno setup compiler. Once it's done, open the application and select 'Create a new script file using the Script Wizard'. You will then be greeted with the following window: Leave the box unchecked. We're going to use the Wizard to make the base of our install script. Fill out all the information in the entry bo

Showing FPS on the screen is an important part of benchmarking your app. In this post we're going to look at how to calculate the number of frames per second and show it on screen. The theory is that we keep track of the last 5 or so timestamps and average over to get the FPS. We keep deleting the last item so the list only has 5 times in it. Lets have a look at the code: 1: import time 2: 3: times = [] 4: count = 5 5: 6: times.append(time.time()) 7: if len(times) >= count: 8: times = times[-count:] 9: fps = "%.2f FPS" % (count/(times[-1] - times[0])) 10: cv2.putText(frame, fps, (0, 20), cv2.FONT_HERSHEY_SIMPLEX, 1, (0, 255, 0), 1, cv2.LINE_AA) First import time, which is required for this to work. Then I define two constants which will be used in the function. Remember this code will run every time the videoloop runs, it adds the time to the list. If the list gets too long, get the last bit using indexing. Then work out the av

For a long time now I couldn't find any help online for my problem. I want to make my own image viewer, since the one that comes with Windows 10 is so bad, but I want to be able to right click on any image, and select open with my Python application. . Lets take a look at my simple program: 1: import sys 2: 3: try: 4: print(sys.argv[1]) 5: except IndexError: 6: print("Being run without file selected.") 7: 8: input("\n\nPress any key to exit...") I want to just get a simple program working first, i'll build the application later. Normally argv would be used to parse command line arguments into a program but it turns out that when your program is compiled, when you use 'open with' your program, the second argument will be set to the path to which the file is located. The first argument is the name of the program. So the program prints the second argument. If there isn't one, if the program is just run, the
