When I increase the scale of the Graphics2D transform, the line weight increases, and I would rather this not happen. Is there a way I can suppress this? While I am on the subject, is there a way to manage lineweights in Graphics2D at all or independently of scale? Thanks. - Paul Schrum Back to top Daniel Pitts Guest Posted: Mon Dec 25, 2006 2:44 pm    Post subject: Re: Lineweight dependent on drawing scale - how to keep line PaulSchrum wrote: Quote: I am drawing Line2D and Quad2D elements on a JFrame using Graphics2D.

Thanks. - Paul Schrum If you set the stroke to have 0 width, it will draw the smallest possible line on the output device. That may not be what you want, however. The alternative is to adjust the width of the stroke based on the scale factor, but that doesn't work well if you have vastly different scales for x and y. look up Graphics2D.setStroke() Back to top Judy Szikora Guest Posted: Wed Jan 03, 2007 4:45 am    Post subject: Re: Lineweight dependent on drawing scale - how to keep line Daniel Pitts wrote: Quote: PaulSchrum wrote: I am drawing Line2D and Quad2D elements on a JFrame using Graphics2D.

Judy, Thanks. I did not know about this method. I will use that. - Paul Back to top Display posts from previous: All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First         AppletTalk.com Forum Index -> Java GUI Toolkits All times are GMT Page 1 of 1   Jump to: Select a forum Java Newsgroups----------------Java DiscussionsWeb-based java games comp.lang.java 3D Graphics API's for Java Java: Support and criticism Java System Announcements comp.lang.java.api JavaBeans Java and CORBA Java and Databases comp.lang.java.developer Java GUI Toolkits Java Help comp.lang.java.javascript JVM, native methods and hardware comp.lang.java.misc Java Language Programming Security and Java comp.lang.java.setup Java Software Tools comp.lang.java.tech ibm.software.java.linux  Non-English Java Newsgroups----------------Java Language (German)Language Java (Français)Java (Italian)  You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum Powered by phpBB © 2001, 2006 phpBB Group SEO toolkit © 2004-2006 webmedic.
