34_as_raster_methods: As Raster Methods

In vectools: Advanced Vector Toolkit

Description

Create standard raster objects from RImage (SImage and MImage) objects, from this package.

Usage

as.raster.SImage (x, ..., optfit=FALSE,
    colf = vt3.linear.shader (reverse=invert),
    invert=TRUE)

as.raster.MImage (x, ..., which, invert.gs=TRUE)

Arguments

x	An RImage object.
which	Integer, which channel. If missing, all channels are used.
invert, invert.gs	Logical, if true, reverse the colors. In MImage, ignored, except for GS and GS-A (one and two channel images), or single-channel images via the which arg.
optfit	Logical, if true, fit colors to a reduced interval (min value to max value), increasing the visible color variation.
colf	A function that maps a numeric matrix to a character matrix of R colors. This includes a shader function from this package.
