Hi All,

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.

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:

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.

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

Perhaps too we need a special JME newsgroup.

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...

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

I got it.. I have to compute it by myslef.

Can we find out the CPU clock of phone ?

I am afriad the phones can't support me enough speed, due to I want as real
time as possible applicatoin.
