Well, just so the rest of you don't spend two days debugging this like I
did, it appears that imagesource caches its image and doesn't reload the
file from disk as long as the file name remains the same.
In my project, a user selects an image to be displayed in a field. I set
the imagesource of a character in the field to do that. I also copy the
image to a special project folder and give it a predictable name so I
can use it later for other things without tracking it. That means that
every time the user chooses a new image, the file name stays the same
but the image content changes.
I guess we can't do that. The only time the image appears correctly is
on first launch. All future references to it load the *old* image, not
the changed one.
I'll have to rewrite a bunch of scripts to track file names, unless
someone can figure out how to force Rev to re-load the image from disk
on demand. That's what I'd prefer.
If you want to try it, make a field and a button. Put this into the
button script:
on mouseUp
answer file "Choose an image"
if it = "" then exit to top
set the cImg of this stack to it
put "a Test Header" into fld 1
set the imagesource of char 1 of fld 1 to ("binfile:"&it)
end mouseUp
Now behind Rev's back, change the image in an image editor so it looks
different and resave it. Then run this in the message box:
get the cImg of this stack
set the imagesource of char 1 of fld 1 to ("binfile:"&it)
No change. Your old image will still be there. If you can figure out how
to re-load, I'd love to hear it.
