Convert Binary Snapshot Output to PNGs
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.
