getSquareSwatchIES

Used to get the IES/EULUM emission pattern plotted into a square rgb buffer of size "resolution". The caller is responsible of freeing the buffer "buf" after using it.

Language	Syntax
C++	real getColorSpaceGamma(byte getSquareSwatchIES( const char* file, int resolution, unsigned char*& buf )
Python	float getColorSpaceGamma()

...

getLastError

Returns the latest error occurred, Cerror is defined in error.h. Useful for finding out i/o problems when reading/writing MXS/MXI files.

Language	Syntax
C++	Cerror::error getLastError()
Python	int getLastError()

...

getLastErrorString

Returns an human readable string containing the latest error occurred.

Language	Syntax

list getSquareSwatchIES( str file, int resolution )

Parameters

Type	Name	In/Out	Description
const char*	file	in	IES/EULUM file name.
int	resolution	in	Resolution requested. Output buffer will have resolution * resolution * 3 values.
unsigned char*&	buf	out	Output buffer containing the emission patter.

Return value

C++

0 = Error getting IES/EULUM emission pattern.

1 = Success.

Python

List of size = resolution * resolution * 3, containing the RGB emission pattern.
