Hi,
With the switch to and from tool mode, the image and the player are
one frame apart, e.g. it should run like this:
Frame Player Image
22 22 --
22 22 22
27 27 22
27 27 27
32 32 27
32 32 32
But instead it runs:
Frame Player Image
22 22 --
22 22 --
27 27 --
27 27 22
32 32 22
32 32 22
So I am getting the buffer from the *previous* frame of the player.
Try not using imageData, use "the text of" or just "put" instead:
put myVar into image "imageThumbnail"
or:
set the text of image "imageThumbnail" to myVar
I have changed the code to use the "set the text of" form, but it
behaves the manner. Also the Stack is flakey, sometimes when I double-
click on the player object in the IDE to get its property inspector,
RunRev Crashes with unexpected quit.
Here is the modified function:
local sgOldImageData
------------------------------------------------------------------------
------------
--
-- PDFGetFrameThumbnail
--
------------------------------------------------------------------------
------------
function PDFGetFrameThumbnail theFrameNumber,theThumbnailFilePathName
local myCurrentTime
local myImageData
local myFrameRect
local myWindowID
local myMovieFilePathName
--
-- Set up the Rectangle for the Player Frame
--
put the rect of player "PlayerThumbnail" of card 1 of me into
myFrameRect
put the windowID of this stack into myWindowID
--
-- Calculate the Position in the Movie and Play the Frame
--
put the fileName of player "PlayerThumbnail" of card 1 of me into
myMovieFilePathName
--set the filename of player "PlayerThumbnail" of card 1 of me to
empty
--set the fileName of player "PlayerThumbnail" of card 1 of me to
myMovieFilePathName
put theFrameNumber * 24 into myCurrentTime
set the playSelection of player "PlayerThumbnail" of card 1 of me
to true
set the startTime of player "PlayerThumbnail" of card 1 of me to
myCurrentTime
set the endTime of player "PlayerThumbnail" of card 1 of me to
(myCurrentTime + 1)
start player "PlayerThumbnail" of card 1 of me
choose pointer tool
wait .25 seconds with messages
--
-- Grab the Frame
--
--put empty into image "ImageThumbnail" of card 1 of me
put empty into myImageData
set the alwaysBuffer of the templateImage to false
export snapshot from rect myFrameRect of window myWindowID to
myImageData as JPEG
choose browse tool
wait .25 seconds with messages
set the text of image "ImageThumbnail" of card 1 of me to myImageData
if myImageData = sgOldImageData then
breakpoint
end if
wait 1 seconds with messages
put myImageData into sgOldImageData
return myImageData
end PDFGetFrameThumbnail

There is a subtle difference between imagedata and the content (the
"text") of an image. In Scott Rossi's example, he also uses "text"
and it works.
