set the extension version number
• template
void write (const std::vector< long > &first, long nElements, const std::valarray<
S > &data, S ∗nullValue)
Write a set of pixels to an image extension with the first pixel specified by an n-tuple,
processing undefined data.
• template
void write (long first, long nElements, const std::valarray< S > &data, S ∗null-
Value)
write array to image starting with a specified pixel and allowing undefined data to be
processed
• template
void write (const std::vector< long > &first, long nElements, const std::valarray<
S > &data)
write array starting from specified n-tuple, without undefined data processing
• template
void write (long first, long nElements, const std::valarray< S > &data)
write array starting from specified pixel number, without undefined data processing
• template
void write (const std::vector< long > &firstVertex, const std::vector< long >
&lastVertex, const std::valarray< S > &data)
write a subset (generalize slice) of data to the image
