Information about the package, leptonica, which is shipped with common Linux distributions. The leptonica package is designed for, C library for efficient image processing and image analysis.
Package Name:
leptonica
Summary:
C library for efficient image processing and image analysis
Description:
The library supports many operations that are useful on * Document images * Natural images Fundamental image processing and image analysis operations * Rasterop (aka bitblt) * Affine transforms (scaling, translation, rotation, shear) on images of arbitrary pixel depth * Projective and bi-linear transforms * Binary and gray scale morphology, rank order filters, and convolution * Seed-fill and connected components * Image transformations with changes in pixel depth, both at the same scale and with scale change * Pixelwise masking, blending, enhancement, arithmetic ops, etc.

Control the leptonica package with the following handy commands outlined below.
yum install leptonica
This command will install leptonica on the server.
yum remove leptonica
This command will un-install leptonica on the server. When you run this command, you will be asked if you are sure that you want to remove leptonica, so you have to manually confirm that you want to do this.
yum -y remove leptonica
This command will un-install leptonica on the server. When you run this command with th e -y flag, you will not be prompted to check that you are sure you want to remove the package - so be sure you absolutely want to remove leptonica when using the -y flag.
yum update leptonica
This command will update leptonica to the latest version. When you run this command, you will be asked if you are sure that you want to remove leptonica, so you have to manually confirm that you want to do this.
yum -y update leptonica
This command will update leptonica to the latest version. When you run this command with the -y flag, you will not be prompted to check that you are sure you want to remove the package - so be sure you absolutely want to remove leptonica when using the -y flag.
yum info leptonica
This command will show you core information about the leptonica package.
yum deplist leptonica
This command will show you the dependencies for leptonica. Thankfully, when using Yum, if dependencies are required, these are also installed at the same time so you don't have to worry too much about that.
yum check-update leptonica
This command will check if there is an update waiting on leptonica. When you run this command this will return nothing if there is nothing to update, or, will return the package name if the package is due to be updated.
