Functions

uint epr_get_pixel_as_uint (const EPR_SRaster *raster, int x, int y)
 This group of functions is for getting the values of the elements of a raster (i.e.
int epr_get_pixel_as_int (const EPR_SRaster *raster, int x, int y)
float epr_get_pixel_as_float (const EPR_SRaster *raster, int x, int y)
double epr_get_pixel_as_double (const EPR_SRaster *raster, int x, int y)

Function Documentation

uint epr_get_pixel_as_uint ( const EPR_SRaster raster,
int  x,
int  y 
)

This group of functions is for getting the values of the elements of a raster (i.e.

pixel) in a type-safe way.

Parameters:
rasterthe raster which contains the pixel, must not be NULL
xthe (zero-based) X co-ordinate of the pixel
ythe (zero-based) Y co-ordinate of the pixel
Returns:
the typed value at the given co-ordinate.
int epr_get_pixel_as_int ( const EPR_SRaster raster,
int  x,
int  y 
)
float epr_get_pixel_as_float ( const EPR_SRaster raster,
int  x,
int  y 
)
double epr_get_pixel_as_double ( const EPR_SRaster raster,
int  x,
int  y 
)
