What is libpng-dev?

(The following description is unconfirmed as of May 14, 2020)

libpng-dev is one of the libraries for reading, writing and editing PNG images.

It is necessary to read "png.h" in the C language source file.

In Perl, there are modules that use "png.h" to read and write PNG images. An example is Imager::File::PNG, Imager's PNG image read / write module.

In order to install Imager::File::PNG, "png.h" must be installed in the include directory and the corresponding shared library "libpng.so" must be installed in the library directory.

Installing libpng-dev installs the "png.h" header and the corresponding shared library.

On the Web, PNG, GIF, and JPEG images are often uploaded, so install the PNG library.
