Problem with polygon graphics in ImageBlender application

PauPérez_Puigcerver — Fri, 12 Nov 2010 11:52:35 GMT

Hi,

I'm using the application ImageBlender to make a HTML page to print, with the image returned by application.
The application works fine with points, polylines, and texts graphics, but not with polygons. When I draw a polygon whith any polygon symbol, the application doesn't return any image.

When I choose Default polygon symbol, the graphicList variable has this value (polygon with 3 points): FILLPOLYGON;0_0_0_0_0_0_0.25;302,190%406,205%378,291$FILLPOLYGON;0_0_0_0_0_0_0.25

And with Solid: FILLPOLYGON;255_0_0_255_255_0_0.5;322,137%469,182%309,281$FILLPOLYGON; 255_0_0_255_255_0_0.5
I don't undertand this part of variable: $FILLPOLYGON;255_0_0_255_255_0_0.5

Which format does the application use for polygons?
Does anybody know what happens?

Thanks

If I replace FILLPOLYGON with HOLLOWPOLYGON or DASHPOLYGON, it also works fine.

Finally I have a solution.

The problem was the transparency parameter passed to the application.
In Default.aspx, the parameter was passed with point as decimal delimiter, and the application works with coma delimiter (at least on my server).

This is the solution:

var transPol = String(dojo.number.round(graphics.symbol._fill.a,2));
graphicSymbol += "_" + graphics.symbol._fill.r + "_" + graphics.symbol._fill.g + "_" + graphics.symbol._fill.b + "_" + transPol.replace(".",",");
//graphicSymbol += "_" + graphics.symbol._fill.r + "_" + graphics.symbol._fill.g + "_" + graphics.symbol._fill.b + "_" + graphics.symbol._fill.a;
