Hi All,
Could you please advice the function call?
or we have to coding byself and then draw it as new picture?

Thank you very much!

Best regards,
Boki.

Most of us here are J2SE types. I feel foolish giving you J2SE
solutions to your JME problems. Perhaps you could prepare a short
essay on that what and what is not available in JME from J2SE.

Perhaps too we need a special JME newsgroup.

I think that is fine, I can try it if you can provide J2SE solution.

Best regards,
Boki.

They wouldn't work anyway on a constrained device, or would be so slow
as to be useless.

I've already referred boki in past to the KVM-INTEREST mailing list,
which has as members people from the various expert groups, the
companises who provide the market implementations, etc. While a Usenet
newsgroup would be nice, it would be easier for boki and others to use
the existing active source for information...

To find out the size of the screen:
See http://mindprod.com/jgloss/coordinates.html

To get images on screen,
http://mindprod.com/jgloss/image.html

Note that Graphics.drawImage all by itself will scale, often when you
did not mean it to.

To do fancy transforms:

The javax.microedition.lcdui.Graphics class does *not* scale images.

There are no methods in javax.microedition.lcdui.Image for scaling an
image. The image can only be displayed at the size for which it's encoded.
