I was having issue wit this script periodically. The original version of this was real a hack-job of Holger Klemms original. This new version utilizes tables in a manner that I hope will make the code easier to follow and understand, but also allows for certain functions to be re-used throughout (and potentially in different scripts as well). In general:
Each program (align image stack, enfuse, exiftool) how has a table that contains information about that program, this includes a sub-table that contains argument data for the program.
There is a GUI table which contains all gui elements. Those elements are split into sub-tables within GUI based on what aspect of the scrpt behavior they relate to (AIS, ENF, Target File, Presets, etc...)
These two structures (and the similarities between them) have allows me to create loops which populate the arguments from the GUI and vice-versa, this is all done through an intermediary preference, the "active" preference.
Whenever a change to a GUI element occurs the associated member of hte active preference is updated. then when it becomes time to build an argument string for a program command the active preference is read from and the value contained within is used. This works fine for all GUI elements that have a "changed" or "clicked" callback, as they can remain up-to-date real time. Sliders and Entry boxes do not have this, so at a certain point withing the script the GUI values are read directly for these elements and written to the associated active preference field.
As you will see about 50% of this code is simply building all the GUI elements and making sure that the initialization value for that element is valid (via the InRange() function). The actual heart of the program and it's functions really only takes up about 300 lines (starting at 180 and going through 476). That is broken down into multiple fairly concise functions. Hopefully this makes maintenance, feature enhancement, and troubleshooting much easier in the future.
I also made a few UI tweaks. This script use to create such a massive list of GUI elements that it was a nuisance when actually using it. They are now grouped into three containers for AIS options, Enfuse options, and target options. Only one of these options containers is displayed at a time. Additionally, I removed all the registered preferences I had before, so now I only register 3 options to enable user to point towards the program binaries.
1) Moved check_if_bin installed to run only once, when script first loaded (rather than every time it is called)
2) Changed executable path preferences per Bill's suggestions
dt.preferences.register("executable_paths", "align_image_stack",
dt.preferences.register("executable_paths", "enfuse",
dt.preferences.register("executable_paths", "exiftool",
3) Replaced custom block of code with df.create_unique_filename
4) Quoted paths in run commands for linux and MacOS (I still experience failures if I quote anything in the run command aside from the .exe path on windows)
5) Changed LUA API compatability check for 5.0.0 only
Tested on Windows and MacOS
HDRMerge: Add easy access to HDRMerge from within dt
enfuse_pro_2: Updated version of Holger Klemm's popular enfuse plug-in. Adds some features and cross-platform compatability
OpenInPS: add ability to open or export selected file with Photoshop
* added checkbox to allow user to launch hugin in gui mode
* changed the logic so hugin will write temp files to tmp directory and then move the final result to the directory of original source files. this improves speed when original source files are on network mapped drive
* added some additional error messages
* added preference requiring user to specify the paths for hugin, hugin_executor and pto_gen needed for this plguin
* added preference to allow user to choose to launch hugin in GUI mode
* minor fix to the way files are handled; due to some versions of hugin_executor not writing out to the path specified in --prefix, assume we are working in the tmp directory and then move the file afterwards
* handle stiching all from hugin_executor without the gui
* automatically create the panorama file name based on first selected file plus _pano
* automatically detects if output file exists, if so use an unique name
* delete temporarily exported file
