limit to scrolling width?

[Steve]

I am finding that there seems to be a limit to the width of a photo that can
be used in ppt. I am using ppt2003. I am attempting to take a very wide
panarama (10x screen width) and do a motion path that essentially slowly
scrolls the entire jpeg from left to right. I set it up, and the image
scrolls a certain amount, maybe 4x the screen width, then the picture is
truncated. It just ends, as if it is the actual end of the photo, and runs
off the screen. What happened here?
Thanks,
Steve

Hi Steve,

From what I've seen you're absolutely right. The work around for this is to
get a very large image and , it in half, twice. Then put them side to side
and let them move. PowerPoint will see it as two separate images and not
have a problem. The things you have to do to get a result ;-)

PowerPoint renders an area about 1 screen dimension out from the slide in
all directions, so if your picture exceeds this area, it will not be
rendered.

However there are 2 work-arounds for this.

1) Split the image (as Glen suggested). Cut the picture in quarters. Then
animate the pieces to look seamless using the delay function (removing the
smooth start and stop effect options). This is a little tricky, but will
work as long as the end-user is using the PowerPoint 2002, 2003 or the new
viewer.

2) Use VBA to move the image (with an acknowledgement to all the limitations
of using VBA in a computerized presentation environment). This is not as
smooth an effect but can re-render the image as it is moved, allowing for
very large scale images to be used. See
http://billdilworth.mvps.org/large_scale_image_scrolling.htm for details in
how to set this up.

I am a little unclear here (nothing new). So, I cut up the image and lay
the pieces next to each other. How shall I move them as a unit? Group
them? Arrange a separate motion path for each piece and have them run
together, at the same speed? My experiments are not yielding much.

OK, to do your suggestion #1, in order to create a sliding panarama that
begins and ends inside of the frame, I believe I need do the following -
this is a bit hard to describe here but here goes:

This pan is to scroll from right to left.

I cut the pan into, say, four pieces. Each piece is an "allowable" size by
the rule you describe. I take the first piece and arrange it so that the
left edge aligns with the left edge of the screen. The other three sections
are stacked upon each other, the left edge of each aligning with the RIGHT
edge of the screen.

The motion path for the first three sections takes them out of the frame on
the left. The path for the last section moves it until the right edge of
the section aligns with the right edge of the frame.

Lets say each section is three screens wide.
Lets say that each screen-width moves across the screen in 10 seconds.

The first section is set to take 30 seconds to move clear out of the frame.
The second section starts 20 seconds after the first.
The third section starts 30 seconds after the second.
The fourth section starts 30 seconds after the third.

Damn. That was easier said than done, and it wasn't easy to say. Does this
sound right to you?
