Built-in module rgbimg

rgbimg

The rgbimg module allows python programs to access SGI imglib image files (also known as .rgb files). The module is far from complete, but is provided anyway since the functionality that there is is enough in some cases. Currently, colormap files are not supported.

The module defines the following variables and functions:

$\begin{excdesc}{error} This exception is raised on all errors, such as unsupported file type, etc. \end{excdesc}$

$\begin{funcdesc}{sizeofimage}{file} This function returns a tuple \code{(\var{x}... ... RGB pixels, and 1 byte greyscale pixels are currently supported. \end{funcdesc}$

$\begin{funcdesc}{longimagedata}{file} This function reads and decodes the image ... ...format is suitable to pass to \code{gl.lrectwrite}, for instance. \end{funcdesc}$

$\begin{funcdesc}{longstoimage}{data\, x\, y\, z\, file} This function writes the... ...per pixel. These are the formats returned by \code{gl.lrectread}. \end{funcdesc}$

$\begin{funcdesc}{ttob}{flag} This function sets a global flag which defines whet... ...p to bottom(flag is one, compatible with X). The default is zero. \end{funcdesc}$
