Publisher: Shaded PowerPoint Objects Copy Over Banded

Publisher: Shaded PowerPoint Objects Copy Over Banded

Q103642

-------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Publisher for Windows, versions 2.0, 2.0a
-------------------------------------------------------------------

SYMPTOMS
========

When you copy shaded PowerPoint objects into Publisher 2.0, their
smooth shading is replaced by ugly banding. This also occurs when you
embed PowerPoint slides into Publisher.

This is only a display problem. The shaded PowerPoint objects print
correctly from Publisher.

STATUS
======

Microsoft has confirmed this to be a problem in Publisher versions 2.0 and
2.0a. This problem was corrected in Publisher version 3.0 for Windows 95.

MORE INFORMATION
================

Although Publisher 2.0 can display 256 colors, its generic palette
does not include 37 tints or shades of the same color. For instance,
you may create a shaded object in PowerPoint that uses 37 different
tints of blue. Publisher's standard 256-color palette may only include
six tints of blue. For this reason, the shading is represented in
Publisher by only six bands of color.

PowerPoint, on the other hand, can display 37 shades of the same color
because it manages and updates its palette dynamically to include
whatever colors it needs in order to display the object(s) on the
slide.

This display problem does not occur in Publisher 1.0. When you copy
shaded PowerPoint objects into Publisher 1.0, the shading displays
correctly.

Publisher 1.0 behaves differently in this instance than Publisher 2.0
because Publisher 2.0 uses palette management to make sure that the
colors you see in a picture won't change when you import a second
picture. Publisher 1.0 does not use this palette management, so you
may import a picture, then import a second picture, and the colors in
the first picture may change. The drawback of the palette management
used in Publisher 2.0 to prevent this problem is that individual
pictures may not display as well.
