Line width

[cassioli]

It looks like j2me does not implement WIDTH parameter for drawing lines!
Does it exist any workaround? Any additional library?!?
My program draws a map, and line color is essential for the user: I can't just draw 1-pixel wide lines!

Hi,

I dont know any additional lib if it is, but work around sure have..

Just draw a rectangle, fill a color in, does it make a line bigger.......


cheers

yes... and what about an oblique line?

hi,

if ur app heavily uses different type of line, i think u should develop ur own libs.

I never try this in J2ME, but did it in very beging programming language (Pascal), a thicker line is in fact a set of thin line.
a line is a set of point.
To draw a oblique line, u have to know its Orbit, like a parabol y= x*x, a line y=ax+b...etc
That's my idea. I really hope it can help u.

Thanks, I already know a couple of algorithms to draw thick lines (trigonometry, Pitagora's theorem,...), but implementing them is boring, and maybe useless, if somebody already did it.

Does anybody know if Nokia UI API can help on this topic?

Or maybe there is a (free) j2me implementation of SVG images?

Hi cassioli,

if you want to use SVG in Java ME, you should take a look at JSR 226:

http://www.forum.nokia.com/document/...w-summary.html

Anyway, if it's only for line-drawing, you'll surely get better results (e.g.: performances) by implementing your own classes/methods that do this on standard Graphics objects.

I see, but I can't understand how to figure out if my device does support it.

For Nokia phones, you can look at the detailed specs of each model here:

Also, you could try to take a look at the J2mePolish interactive database, filtering devices by JSR 226.

fine, it does not. :-(
