The following code displays a GIF image in a Tk window (actually in a Tk label widget within a Tk window).
library(tcltk2) # Tk supports natively gif images, like this one: imgfile <- system.file("gui/SciViews.gif", package = "tcltk2") image1 <- tclVar() tkimage.create("photo", image1, file = imgfile) # Create a Tk window with a label displaying this image win1 <- tktoplevel() win1$env$label <- tk2label(win1, image = image1) tkpack(win1$env$label)
Tk supports natively PNG, GIF, PPM and PGM images. For other formats, you can install the Tk Img package and use
tclRequire("Img") in R to make it available to R tcltk. From this moment on, you have also access to TIFF, JPEG, BMP, XBM, …, images.
