Paul:
You’re right! Thanks for correcting this. This “from Rect” part is completely
unnecessary. My earlier version, which captured the screen, also captured any
IDE windows in from of the capture region. However, even with the RECT part of
the command, the windows in front of the capture
Hi Bill,
Sorry for the delay replying, I’ve been away from home for a few days.
I don’t think line 6 will give the result you are looking for, I would change
it to:
6. export snapshot from Group snapshotGrp with metadata theMetadataArray to
image mySnapShot
i.e. Remove the “from rect” part
Paul:
FYI, I set up a test stack to figure out how to use the “from object” method of
getting a snapshot image. Here’s the steps I followed:
1. put all images that are to be captured in a group.
2. set the group rect to the desired snapshot rect
3. Lock the group rect
4. Set the group to scaling
Paul: One more thing. My test uses a variable “theMetadataArray”, which is not
set, so is blank. The manual states:
metadata - The metadata is an array of metadata. Currently the only key
supported is density with a value in pixels per inch (ppi).
So, I wonder if, to get the benefit, I have
Paul:
Thanks, I’m trying it out. Of course, I won’t be able to tell if it solves the
problem until the next student has a problem, but it’s a good idea anyway.
Unfortunately, due to the way I’ve set up the data plotting, it’s going to be a
fairly big job. I rely heavily on screen capture, but
Paul:
Thanks for the hint. I do use the newer “from” syntax.
export snapshot from rect snapRect to image mapSnap
Thanks,

Bill,
I’ve done a few tests and it appears to me that from rect” still relies on the
screen output from the computer, whereas “from object” allows LC to render an
image of an object independent of the screen hardware.
Try this:
Move your stack so the map image is half off the screen, then

I got it. Haven't seriously used it yet, but will very soon.

The from option renders the object into a new buffer set up just for the

Thanks for testing this. It does give me more confidence that it’s some oddity
on the student’s computer.

The pixellation should show up on the steps you took.
However, I don’t see it and another LiveCoder who downloaded it and played it
on Windows 8 doesn’t see it. Lowering the screen resolution shows the effect,
but that would show the entire window pixellated, and that isn’t what is shown
_Where_ and _when_ should the pixelation show up exactly?

Keeping in mind that the info I got was from my teacher/collaborator, Sabina

Okay. With this info, I'm unable to see any pixelation.
I have tested the app on a 2.2 Ghz laptop with 4 GB built-in memory
running Windows 8.1, i.e. nothing fancy and your students probably have
a similar or better configuration. The sytem is Dutch.

I performed step 1 till 7. What are the steps to check if anything
relevant is extremely pixelated?

I had a look at your app. There is no export snapshot button or menu
item. Please, provide instructions as brief as possible.
