[JAVA2D] Performance problems on multiple monitors

[Dimitri del Marmol]

Hi everyone, I noticed a strange behavior in a Swing application using JAI. The application involves displaying images on JPanels contained in a JFrame. Operations allowed on the displayed images involve contrast modification, zooming, panning... Multiple monitors are supported. The strange thing is, if the frame is opened on the second monitor, the performances of the imaging operations are noticeably slower than when the frame is opened on the first monitor. Even stranger: if the frame is dragged across the desktop to the first monitor and then back to the second, the operations are fast again. Has anyone noticed a similar behavior ? I posted this on the JAI-INTEREST mailing list and the answers I received pointed at Swing/JFC since other users had also experienced this problems when using other media API's (JMF) and even in "non image-related" applications. I'm posting it here too since, even though I don't have the slightest clue to how Multiple Monitors support have been implemented, it seems to be a Java-2D feature... Any suggestion is more than welcome :-) Dimitri *********************************************     Dimitri del Marmol     [EMAIL PROTECTED]     Telemis s.a.     Tel: +32 (0)10 48 00 14     Fax: +32 (0)10 48 00 20     Avenue du Grand Cortil, 34     B-1348 Louvain-la-Neuve ********************************************* =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA2D-INTEREST".
