Soon-to-be released as Jmol 14.0.12/14.1.12, this update fixes the bug
Angel just reported, improves performance, and adds some pretty nifty
ZIP-file capabilities.
I decided that if I am adding features, I should also put time into
reducing code size. So that's what I've been doing the past two days. Happy
to report that despite those improvements, this version reduces the base
load size by 43K (since last week), and the full package size by about 100K
(since last year). In addition, my careful checking of what modules were
being loaded and seeing what I could do about that means that PDB files
will require about 200K less upon download, so they should load much
faster. Mostly this is just be giving field variables more compact names,
like "this.ms" instead of "this.modelSet" (2K), "this.ce" instead of
"this.propertyColorEncoder" (1.6K), etc. A little harder to decipher the
code, but I can live with that.
With last week's 900% speed-up in molecular isosurface creation in Java
(about 300% in HTML5), the performance is really coming along. Every time I
test JSmol it seems to be faster and smoother and more Java-like. Sure has
come a long way in a year and a half. Very satisfying!
Fixes since 3.17 include:
___JmolVersion="14.1.12_2014.03.21"
bug fix: getProperty() function does not recognize a list as a variable and
returns it as a string (Angel)
bug fix: Dsn6Reader.java misnamed, causing EDS map file load error
in JavaScript only. (I did not know that was even possible!)

New features:
The real news is that now we have some very powerful PNGJ/ZIP capabilities.
You can unpack PNGJ files and repack them, adding files if you like, and
you can create and modify ZIP files -- in JavaScript, of course. Thanks to
Chuck Shubert and Ivan Ceraj (MIT) for getting me going on that.
new feature: x= format("JSON", data)
-- simple way to generate JSON code.
new feature: x = format("base64", data)
-- creates base64-encoding of the data
-- prepends the string with ";base64,"
new feature; binary byte array
-- from array(s) where s starts with ";base64,"
-- from binary associative arrays
new feature: binary associative arrays
-- Any array containing "$_BINARY_$" as a key.
-- Values may contain raw byte array data, but need not.
-- Can be expanded or changed, just like any associative array.
-- Seen in string form when in a string context.
-- .type of elements will report "byteArray"
new feature: x = write("PNGJ")
-- Creates a binary associative array equivalent to writing a PNGJ file
-- Contains keys "_IMAGE_", "JmolManifest.txt", "state.spt"
and all associated files.
new feature: write VAR x "filename"
or write @x "filename"
-- Where x is a binary array or a binary associative array.
-- When x is a binary array, writes binary data to a file.
-- When x is an array, creates a ZIP file
(or PNGJ file, if _IMAGE_ is present and is PNG format),
automatically converting strings starting with ";base64," to
byte arrays in the ZIP file. To do the same with x a binary
array, just use @{array(x)} instead of @x.
new feature: x = load("myfile",true)
-- Creates a binary associative array variable x that contains the
contents of
the file file.
-- data are stored as raw bytes.
-- If the file is a standard file, the key "_DATA_" will hold the file
data.
-- If the file is a PNGJ file, the key "_IMAGE_" will hold the image data,
and additional files are keyed by file name.
-- If the file is a zip file, the files are keyed by file name.
-- Note that x = load("myfile") without "true" loads the contents of
the file into x and, if the file is a PNGJ or ZIP file, just loads
the list of files in the collection, not the actual data.
Actually, the really really interesting news is that the reorganizing of
the code that I am doing is making for capabilities that go way beyond
Jmol. Want to create Zip files for any purpose? You can do that. Pull an
image out of a Word document? Sure. Want to create PDF files from data on a
web page? Have that.
That's because the way this works, I've basically produced a JavaScript
library that can do anything Java can do. Very interesting...
Have a good weekend. I'm taking a break!
