What is libtiff? libtiff is a library for manipulating and displaying many different image formats. It was originally created by Michael D. Smith in 1987, and has been in use since the early days of digital photography.
With libtiff, it’s possible to manipulate images in many ways, such as convert them to black and white or change their color gamut. It also supports many common image file formats, including TIFF, XVID, GIF, PNG, JPEG-LS and others.
One example of using libtiff is displaying an image as a preview when saving it as a JPEG file. Another common task that can be accomplished with libtiff is display a 100% transparent background over an image when saving it as a PNG file.
Additionally, there are other features that make libtiff useful for photographers. For instance, it has features that allow you to perform photo editing on your images without having to download additional software like Adobe Photoshop.
