![]() ![]() The first step is to try to repair the image using a photo editing program. There are a few ways to try to repair a corrupt image, but unfortunately, there is no guarantee that any of these methods will work. ![]() In some cases, a corrupt image may only have a few bad pixels, while in others the entire image may be distorted. It will then continue to loop until the ESC key is pressed.When an image becomes corrupt, it can often become unusable. The above ttings file will cause JPGCorrupt to start full screen, processing Short Test.txt with testimage.jpg and Long Text.txt with The-Great-Gatsby-upres.jpg, in order. Order they will be processed in the ttings file. The list of files to be process are listed, in the JPGCorrupt supports running through a list of text/image file pairs sequentially. It now works completely in memory, but I added the ability to save an image at any point. Originally I implemented this such that it saved every JPG along the way.I tried implementing a mode where it over writes JPG data sequentially but it regularly completely corrupted the file. The text is randomly spread around the file.I tried 64 bytes and got unreadable files quickly. I intentionally didn't read any JPG specs but I assumed there's some form of header. I currently avoid overwitting JPG data in the first 256 bytes of the file.1.3 - Added tracing (JPGCorrupt.log in executable directory).1.2 - More feedback from Tom: Now supports queuing of multiple files, auto start, and persistent configuration.1.1 - Addressed feedback from Tom: Background is now black, Loop mode, removed text display. ![]() I tried inserting the text data (instead of overwriting) but that caused the files to be quickly unreadable.Each word of the text file overwrites JPG data at a random spot.The larger the JPG image the slower the app is, but the more interesting the results.After it saves them they appear to be openable by anything (e.g. Paint.NET opens them fine and saves them fine.Paint (Windows) opens them fine, but fails to save them.Photoshop tends to not want to open these files.Flickr refuses to upload some of these images.Windows picture preview is very different. FireFox, IE, and Chrome all have subtle differences. Some JPG renderers display the corrupt JPGs differently.It appears that those saved by Photoshop are more resilient than others. Some JPG files get massively corrupted really quickly.On enabling a queue of text/image files to be processed. See Queing Multiple Files below for more details AutoStart, FullScreen, & Loop control the app's behavior. The settings file will be created in the directory the JPGCorrupt.exe file is in. The ttings file will be created the first time the app runs.Loop mode will cause the corruption process to repeat over and over.The "Save Current" button will let you save the very latest frame.When in full screen mode, ESC will stop it.Click on the Go (or Go Full Screen) button.an image from the movie The Great Gatsby) ![]() Watch a video of JPG Corruptor in action: Instructions The JPG file is "corrupted" by randomly overwriting data in the file with the words in the text file.Įxample JPG Corruptor Output What this image looks like after being corrupted by the first two chapters of The Great Gatsby This application takes a text file and a JPG file and displays each iteration of the JPG file as it is corrupted by the words in the text file. It turns out that most JPG files are quite reslient to such corruption and the resulting images, when rendered, can be quite interesting. The idea is to create a "movie" of a JPG file being corrupted through the overwriting of JPG binary data with words from the text of a book. Is using it for a project in an art class. JPG Corruptor has been inspired and commissioned by my brother-in-law who is an art student.
