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.
