Applescript droplet to generate png previews using LDView

[Ramón Figueroa-Centeno]

Aloha,

The following saved as an application from the AppleScript Editor generates png previews:

Code:

property ldview : "/Applications/LDView/LDView.app/Contents/MacOS/LDView"

on run
    set root to choose folder with prompt "Please select folder."
    generatepreview(root)
end run

on open root
    if folder of (info for root without size) is true then
        generatepreview(root)
    end if
end open

on generatepreview(root)
    
    set suffix to "\\( -iname \"*.ldr\" -o -iname \"*.mpd\" -o -iname \"*.dat\" \\)"
    
    set root to (POSIX path of root) as string
    set root to quoted form of ((characters 1 through -2 of root) as string)
    set ldrs to do shell script "find " & root & " -type f " & suffix
    
    repeat with ldr in paragraphs of ldrs
        try
            set dirname to do shell script "dirname " & quoted form of ldr
            set png to ((characters 1 through -5 of ldr) as string) & ".png"
            do shell script "cd " & dirname & "; " & ldview & " " & quoted form of ldr & " -SaveSnapshot " & quoted form of png
        end try
    end repeat
end generatepreview

It assumes that LDview is in the application folder. Modify the "ldview" property otherwise.
