# podofocolor(1)

modify colors in a PDF file.

## NAME

podofocolor - modify colors in a PDF file.

## SYNOPSIS

**podofocolor** \[converter\] \[inputfile\] \[outpufile\]

## DESCRIPTION

**podofocolor** is one of the command line tools from the PoDoFo library that provide several useful operations to work with colors in PDF files. It can parse and/or modify all colors or colorspaces in a PDF file. The modifications can be defined via C++ or a Lua script. Custom conversions like **convert all colors to grayscale** are included. Please note that only colors of vector objects on pages and in XObjects are affected. This tool does not transform colos in images at the moment.

## CONVERTERS

\[converter\] can be any of

dummy - Convert all colors to red. Just a dummy and test implementation which serves as an example for developers.

grayscale - Convert all colors of vector objects in a PDF to grayscale.

lua \[script\] - Convert all colors based on a Lua description. A lua script has to be passed as an additional parameter.
