Hi Paul
I just tried the same thing and got the same result. It works on Mac, not on
Windows.
I also tried exporting the image as a file to see if that made any difference.
export snapshot from rect tRect of player "mediaConvert" of stack
"libHrAPI" to file [filepath/filename.png] as PNG
I got an image file but it is the same as what you see in the image object on
the stack — an image of a white rect inside the player boarder.
So it looks like it is a bug. The snapshot does create a proper png it just
doesn’t grab the current video image inside the player it just gets a white
rect.

I am executing the following 2 lines of code:
export snapshot from rect tRect of player "mediaConvert" of stack
"libHrAPI" to tImage as PNG
put tImage into img "imageConvert" of stack "libHrAPI"
Prior to the export the player has a video load and has the currentTime set to
a particular frame, and I can see in the stack that the player is showing the
correct frame is visible.
I can also see that the image "imageConvert" is also visible, but empty
After the Export Snapshot is executed, it looks like tImage contains valid PNG
data, although I can not tell if it is the correct image
After the Put statement, the image "imageConvert" is set to a white rectangle
with a little bit of the player border on the left and top. It is the same size as the
player where as the empty image I started with was larger.
This is with LC 9.6.7 on Windows 10. This code works on macOS. Does anyone know
if there is a known Windows bug with export a snapshot form a player and any
work around?
