Color depth - 8 bit, 16 bit or 24 bit

[Peter Jackson]

Hi All,
How do I tell what the color depth is of a picture object, I would like to
do:
Shp.Export FileName, shapeFormate

where shapeFormate and FileName are determined by the color depth.
e.g.
Select Case Shp.ImageDepth
Case 0 to 8
shapeFormate = ppShapeFormatGIF
FileName = Shp.Name & ".gif"
Case 9 to 16
shapeFormate = ppShapeFormatJPG
FileName = Shp.Name & ".jpg"
Case Else
shapeFormate = ppShapeFormatBMP
FileName = Shp.Name & ".bmp"
End Select

Or maybe there is another simple way??

TIA

Regards, Peter

Peter,
I don't think there is any way to ascertain the color depth of an
inserted picture. I also don't think you could capture that even while
importing the picture based on the file extension. For example a jpg
could have any of the mentioned color depths you are looking for.
To add even more complexity to the matter, PowerPoint stores all
images, except jpgs, as png files. It leaves jpgs natively jpg.

What are you trying to do with this here. Maybe there are other
thoughts we could bring up about image size that might help.

Hello Peter,

PowerPoint does not have the specific capability that you are looking for.

If you (or anyone else reading this message) think that PowerPoint should
provide a way to display (and perhaps change) the properties of inserted
images or, perhaps even any selection (without having to resort to add-ins
or VBA), don't forget to send your feedback to Microsoft at:

As with all product suggestions, it's important that you not just state

suggestions every day and we read each one but, in any given product
development cycle, there are only sufficient resources to address the ones
that are most important to our customers so take the extra time to state
your case as clearly and completely as possible.

IMPORTANT: Each submission should be a single suggestion (not a list of
suggestions)
