SVGimport problem
Oct 13^th, 2006, 2:03am

Hello,

I just tried to install the "SVGimport" library. And then ran one of the exemples that come with. But I can't do it work : I get the following message in the processing shell :

/tmp/build62372.tmp/Temporary_7883_9714.java:30:14:30:23: Semantic Error: No accessible field named "LINE_STRIP" was found in type "Temporary_7883_9714".

I suppose that the library is not right installed. I am running it under Linux OS and have installed the 117 version of Processing. Do you have an idea to solve my problem.

Thanks a lot.

Thanks very much for your quick answering. I have found what had to be updated in the Michael Chang library. May be I could give the corrected code. Where do you think I could upload this, to make it easily accessible by Processing users ?

Thanks again.

Anyway I give the modifications (in the svgpath.java file) here :

1) Replace 'toFloat' (deprecated) by 'parseFloat' everywhere
2) Modify the drawing routine as following :

parent.beginShape(style);
//parent.vertex(s.paths[p].points[0].x,s.paths[p].points[0].y);

for(int i=1;i<s.paths[p].points.length;i+=3)

{

if(i+3>s.paths[p].points.length)

break;
//parent.bezierVertex(s.paths[p].points[i].x,s.paths[p].points[i].y,s.paths[p].points[i+1].x,s.paths[p].points[i+1].y,s.paths[p].points[i+2].x,s.paths[p].points[i+2].y);
parent.bezier(s.paths[p].points[i-1].x,s.paths[p].points[i-1].y,s.paths[p].points[i].x,s.paths[p].points[i].y,s.paths[p].points[i+1].x,s.paths[p].points[i+1].y,s.paths[p].points[i+2].x,s.paths[p].points[i+2].y);

}

parent.endShape();

3) In the main file :
Replace "LINE_STRIP" (seems to be not used anymore) by "LINES"

You are bloody right. I haven't tested my corrected lib with filled shapes. So the right corrections are :

1) Replace 'toFloat' (deprecated) by 'parseFloat' everywhere
2) Modify the drawing routine as following :

//parent.beginShape(style);
parent.beginShape();
parent.vertex(s.paths[p].points[0].x,s.paths[p].points[0].y);

for(int i=1;i<s.paths[p].points.length;i+=3)

{

if(i+3>s.paths[p].points.length)

break;
parent.bezierVertex(s.paths[p].points[i].x,s.paths[p].points[i].y,s.paths[p].points[i+1].x,s.paths[p].points[i+1].y,s.paths[p].points[i+2].x,s.paths[p].points[i+2].y);
}

parent.endShape();

3)
In svgpath.java
Remove the "int style" parameter from functions "draw" and "images" definitions.

In the main file :
Remove the parameter "LINE_STRIP" :

//mysvg.draw(LINE_STRIP,35,120);
mysvg.draw(35,120);

Thanks again to fry.

It seems to work now.
Hope this will help...
