writeTiff {rtiff}R Documentation

A function to load TIFF images into a pixmap.

Description

Loads a TIFF image from a file and returns the image as a pixmap object, with optional scaling.

Usage

writeTiff(pixmap, fn)

Arguments

pixmap Either a pixmapRGB or matrix containing the image to save. In the case of a matrix, a new pixmapRGB will be created from it. The resulting TIFF file will be RGB, but will appear grey because each channel will be identical.
fn What to call the new tiff file.

Details

This function saves the given pixmap or matrix raster as an unencrypted TIFF image, utilizing libtiff's TIFFWriteEncodedStrip, with the entire raster in a single strip (for simplicity).

Value

None. Used for its handy side effect of creating a tiff file.
