$ pngcheck -ts ${filename-png}

try on your machine

The pngcheck command is a utility used to verify the integrity and validity of PNG image files. When executed with the -ts option, it performs a thorough analysis of the specified PNG file, reporting any possible errors or warnings.

In the command pngcheck -ts ${filename-png}, ${filename-png} is a placeholder indicating that you need to replace it with the actual filename of the PNG image you want to check. For example, if your PNG file is named image.png, the command would be pngcheck -ts image.png.

Executing this command will run the PNG file through a series of tests, including checking the PNG header, compression method, color type, image dimensions, palette, and more. It will then display a detailed report indicating any issues found, such as incorrect formatting, data corruption, or potential problems that could affect the display or rendering of the image.
