MakeSnapshots: Convert Binary Snapshot Output to PNGs

In infraFDTD.assist: IO Help for infraFDTD Model

Description

With the help of MakeSnapshotInfo, converts binary snapshot output files from infraFDTD to PNG format.

Usage

MakeSnapshots(info, outputdir = "./anim", prefix = "snapshot", nums =
1:info$N, dt = 0.1, makesec1 = TRUE, makesec2 = TRUE, makesurf = TRUE,
res = 96, fn_topomap = "topomap.png", width = 480, height = NaN, asp =
1, pointsize = 12)

Arguments

info	Output of MakeSnapshotInfo().
outputdir	Directory where PNG files should be written.
prefix	Prefix to use in output file names (e.g., outputdir/prefix_sec1_001.png).
nums	Vector of snapshot numbers to convert (default is all of them).
dt	Snapshot interval in seconds
makesec1	Logical: should section 1 snapshots be converted?
makesec2	Logical: should section 2 snapshots be converted?
makesurf	Logical: should surface snapshots be converted?
res	Resolution of output PNG files (see ?png).
fn_topomap	File name for topo map output.
width	Width of output images (pixels)
height	Optional: if blank, MakeSnapshots() will find the correct height given the image dimensions and asp. If set, forces the height of output images.
asp	Aspect ratio of images (default 1).
pointsize	Pointsize in output images (default 12).

Details

Use a shell command like 'convert' (imagemagick, available in linux) to make a gif out of the stills.

Value

None, file output only.
