ANN: LR/Mogrify plugin released. Alamy users rejoice!

Question

Hi,
Frustrated by Alamy's 48Mb image size requirement, and the fact that Lightroom's export feature can't automatically resize images by the minimum amount necessary to guaranty that the requirement is met, I've written a plugin to solve the problem and improve my workflow.
The plugin applies ImageMagick's mogrify command to exported images. ImageMagick is a set of powerful, freeware command line utilities for Mac or PC.
Although my motivations were very specific, this plugin could be used by anyone who needs to further post process images using mogrify, and I've therefore decided to release it free of charge. The plugin currently allows the user to resize images using a choice of resizing algorithm and reconvert the resulting image to another format. Users can also enter their own command line parameters to control all the other aspects of mogrify.
I'm willing to improve the plugin to expose other mogrify features via the user interface if enough interest is shown.
It's been tested on Mac. It should work on PC but I can't test it - feedback's appreciated.

Hi.
Doesn't work for me on Windows. Calls to LrTasks.execute() in
LRMogrifyExportTask.lua fail. I spent quite some time on it. Quotation
of file paths really introduces trouble. Seems there is some problem
with quotation mark matching. If you use only one pair of them,
everything is fine. When there are multiple pairs, things get quite
strange...
For example, these command strings are supposed to work:
c:/somepath/someexecutable c:/anotherpath/file
"c:/some path/someexecutable" c:/anotherpath/file
c:/somepath/someexecutable "c:/another path/file"
If I quote both paths, blanks in the first path don't get escaped. Even
worse, I don't know of any other way to escape blanks here than use
quotation marks. Something like "\ " -- no chance(?). I even had a look
at the lua.org source code. Their os.execute() is mapped to ISO/ANSI C's
system() call. No idea what LrTasks.execute() does.
My suggested work-around would be like this, as LR at least allows use
of native file system calls:
-- LRMogrifyExportTask.lua --
-- Run Mogrify
local command = '"' .. opts.path .. '" ' .. commandLine
-- added
local realCommand = command
if WIN_ENV == true then
-- default folder on Windows is user dir -> good
local batchFileName = "lr_mogrify_runner.bat"
io.output(batchFileName)
io.write(command .. '\n')
io.close()
realCommand = '"' .. batchFileName .. '"'
end
-- /added
-- changed
if LrTasks.execute(realCommand) ~= 0 then
-- /changed
