Hi,

i try to generate a jpg with the java2d-api.

I like to generate a calendar for a year, so i make a big offscreen-image
and draw image for the month on it by changing the clipping area for the
Graphic2d:

area.setRect(startX,startY,widthMonth,heightMonth);
g2.clip(area);

I clip the area, draw the image on the offscreen-image, change the clipping
area, draw the image again and so on.
This works pretty fine, but when i change the width of the offscreen-image
to a value greater than 500 px, i get a very curious effect. In the right
lower third of the image the image is drew again. Sounds confusing, so i
made two screenshots which are self-explaining:

This is ok: http://www.krefelder76.de/graphik/calendar_ok.jpg

This not: http://www.krefelder76.de/graphik/calendar.jpg

Knows anybody was is going wrong here?

Thank's.

So long,

Andreas
