Information about the Leptonica Version and Image Format Support

Description

These two functions allow us to query the meta-data about the leptonica library in use. They query the version information about leptonica itself and also the version of each of the image reading libraries it has been installed with.

Usage

leptonicaVersion()
getImageLibs(asMatrix = FALSE)

Arguments

asMatrix

a logical value that controls where the image library versions are returned as elements of a character vector or if the values are decomposed into a matrix giving the major, minor and patch numbers (where available).

Value

leptonicaVersion() returns an integer vector with three element - the major, minor and patch numbers.

getImageLibs() returns either a named character vector or a matrix. For the character vector, the names identify the image file format and the values identify the version of the corresponding library. The matrix is similar with a row for each of the image formats and columns for the major, minor and patch numbers.
