Very interesting. I don't have a great trust of Autodesk either. (It's hard when they keep violating their customers with forced upgrades.) SS On 7/11/07, Larry Becker <[EMAIL PROTECTED]> wrote: > Hi Sunburned, > > I actually got on board with DWF back in 1995 when AutoDesk first > introduced t

Hi Sunburned, I actually got on board with DWF back in 1995 when AutoDesk first introduced the WHIP! web browser plug-in. I got the "free" SDK and started developing an application based on it. Imagine my surprise when I got a letter from AutoDesk saying that they were revoking the licenses of

The unit for line width is defined by the graphics system - so 1 = 1 pt. = 1/72 of an inch (or metric equivalent). Larry On 7/8/07, Stefan Steiniger <[EMAIL PROTECTED]> wrote: > > Larry Becker schrieb: > > Hi Stefan, > > > > We still may wish to change the UI so that it is possible to set > > f

Hi Stefan, We still may wish to change the UI so that it is possible to set fractional line widths as is possible in other programs. That would require more refactoring. It depends on how much control users need. Such capability is always included in programs like Illustrator, and is commonly

A very late response to Larry: so, do you think that your modification of the BasicStyle constructor is now obsolete, since we can use "0" BTW... I am exporting in svg and then prepare my images in illustrator(inkscape). Thus, i don't really have styling problems. but who has the time to do

@Larry: IIRC the zero policy was introduced by Sun as a reaction to some user complains at bugs.sun.com that lines were vanishing when the scale becomes very small. I can't remember when that was done. Before 1.4? @SS: What do you think does Batik? It simply creates elements from g2d.lineTo(new

Larry, I know it is very easy to convert to SVG by using the JTS graphics painted on the LayerViewPanel and the Batik libs. I wonder if some of the problems could be eliminated by using the JTS Goemetries and Layer styling information to convert directly to SVG. Just a thought. The Sunburned Su

More surprises (for me). Someone stop me if this is already documented. If you set the line width to zero, you get very faint lines. The documentation for BasicStroke says, "If width is set to 0.0f, the stroke is rendered as the thinnest possible line for the target device and the antialias hint

Interesting... It turns out that when rendering antialiased lines, Java2D actually draws lines with fractional widths as shown in the attached JumpWindow screen capture. This would make it possible to modify the Change Style line width slider to support floating point values that represent very

Larry, This is a great post. Thanks for documenting some of the problems we are having with the rendering system. Perhaps I need to take a crack at these with my pluggable renderering system, instead of stand alone labels. I'll give this some thought. The Sunburned Surveyor On 6/25/07, Larry Bec
