GpimageCrop: Simple image manipulation

In Rgnuplot: R Interface for Gnuplot

Description

GpimageCrop crops an image GpimageDecimate decimates an image GpimageFlip flips a png image on the X, Y or XY axis GpimagePlot displays an image file on the screen or to a chosen terminal except to a file GpimageResize resizes an image GpimageRotate rotates an image GpimageTile tiles multiple image files together into one Gpimage2PNG converts from any supported format to PNG, the file type is automatically detected Gpimage2image converts from any supported format to other format, the file type is automatically detected

Usage

GpimageCrop(fileIN, fileOUT,x1,y1,x2,y2, filetype='PNG', terminal=NULL)
GpimageDecimate(fileIN, fileOUT, Xdec=2,Ydec=2, filetype='PNG', terminal=NULL)
GpimageFlip(fileIN, fileOUT,flipX=TRUE,flipY=FALSE, filetype='PNG', 
terminal=NULL)
GpimagePlot(fileIN,alpha=FALSE, backgroundColor='', filetype='', 
terminal=NULL)
GpimageResize(fileIN, fileOUT,newWidth, newHeight, filetype='PNG', 
terminal=NULL)
GpimageRotate(fileIN, fileOUT,degrees, filetype='PNG', terminal=NULL)
GpimageTile(fileOUT, matrixFilenamesIn, vectorWidths, vectorHeights,
matrixXscale=NULL, matrixYscale=NULL,alpha=FALSE, filetype='PNG', terminal=NULL)
Gpimage2PNG(fileIN, fileOUT, optional256=FALSE,alpha=FALSE, backgroundColor='')
Gpimage2image(fileIN, fileOUT , filetype='PNG', terminal=NULL,alpha=FALSE, 
backgroundColor='')
