I'm confused, bewildered and befuddled by the behavior of one of my
scripts. It was born under OS-9 and used an FMPro database to store info.
It extracts much of that as lists or just plain text. It then uses this
info to drive "clip2gif" (c2g) and create graphics. Under 9 that all
worked..
I'm now bringing this along to OS-X and mysql (running c2g under classic).
Most of itt works, but now and then when I do a "text items of "
decomposition of a mysql text string, I get (unsurprisingly) unicode text
where I used to get 'plain' text. OK, just coerce it to "plain text",
right? ... well, no ...
given:
set foo to {}
set xText to ... (see below)
tell application "clip2gif"
set foo to foo&{{position:{50,50},drawn text:xText}}
set p to save {300,300} as GIF in picture drawing foo
end tell
set the clipboard to p
The following string concoctions for xText work...
(OSX10.3.7,SE2.0,AS1.9.3)
"Sample"
"Sample" as text
"Sample" as plain text (compiles to ... as string)
but these fail (the clipboard is empty or invalid, though SE shows a
(smallish) PICT object(?) in the result window if you leave off the last
script line)
"Sample" as Unicode text
("Sample" as Unicode text) as text
("Sample" as Unicode text) as plain text
It seems that coercing "Sample" to Unicode text and back is somehow
different from just using "Sample" .. and it isn't clear how I can
reliably coerce text fragments to "plain text" that c2g will digest well.
Write the thing to disk and read it back in (as someone recently
illustrated for a different problem)? Clarifications and suggestions
welcome!
