Hi All,

I want to convert a bitmap to ink data, show it in ink control such as
InkPicture, then I can move strokes from the bitmap, not just set the bitmap
as a background picture.
It seems have a lot work to do. Can anyone help me?
Thanks in advance!

You bet.

What you want to do is, basically, called
"bitmap tracing". There are free tools that
to a good job at it (although they do not directly
produce ink, but maybe you could try to parse
one of the vector formats that they generate).
One such tool is http://potrace.sourceforge.net/
Having little money to spend I don't know about
commercial alternatives ;-)

Regards,
Christian

Good to know.

Thanks for the link. The bitmap vs. vector based samples at the website look
promising.

Where is the source of the bitmap originally coming from? Is it an image of
some sort or is it ink data that you've collected previously using the
Tablet PC API's? If the latter, you can use fortified GIF instead of BMP
which basically is a GIF file with the vector ink data stuffed in a header
so that the GIF can be displayed as usual by anything capable of displaying
GIF images but its constituent strokes can be extracted by the Tablet PC
API's and used as an Ink object again.
