Check if a file is an image from a supported format

plt_check() is a wrapper around the C++ function stbi_info from stb_image.h. It checks whether a file is an image from a supported format. This is useful for checking whether plt_tize() can create a color palette from a file without having to decode the entire file.

Usage

plt_check(path)

Arguments

path

A path to a file to be checked.

Value

plt_check() returns TRUE if the file is an image from a supported format, and returns FALSE for non-image files and images from unsupported formats.

Details

Future versions of this function will expose how to query the width, height, and component count of an image.
