Hi list,
I use ms4.0. and php_mapscript
I have problem with $style->color->setRGB on-the-fly. I try =
something like this:
$class =3D $layer->getClass(0);
$style =3D $class->getStyle(0);
$style->color->setRGB(0, 0, 255);
$style->set ( 'symbol', $sym1 );
$pt->setXY( 2100000, 10100000 );
$pt->draw($map, $layer, $image, 0, "Pt1");
draw blue point ok.
$style =3D $class->getStyle(0);
$style->color->setRGB(0, 255,0); //draw a green point
$style->set ( 'symbol', $sym1 );
$pt->setXY( 2100000, 10100000 );
$pt->draw($map, $layer, $image, 0, "Pt1");
draw green point ok.
$style =3D $class->getStyle(0);
$style->color->setRGB(0, 0,255);=20
$style->set ( 'symbol', $sym1 );
$pt->setXY( 2100000, 10100000 );
$pt->draw($map, $layer, $image, 0, "Pt1");
FAILED, problem draw green point.
I read the discussion above "can I use different symbols in =
thesamedynamiclayer?" betwen September and October 2003 but not found =
the solution at problem.=20
I try create two styles in one class and try move the styles with:
$style->movestyleup()=20
$style->movestyledown().
=20
LAYER
NAME lpt
TYPE POINT
SYMBOLSCALE 20000
STATUS OFF
TEMPLATE void
CLASS
NAME 'ExcVel_0'=20
SYMBOL 'ExcVel_0'=20
STYLE
OUTLINECOLOR 0 0 0
COLOR 255 0 0
SIZE 15
MINSIZE 8
MAXSIZE 20
END
=20
STYLE
OUTLINECOLOR 0 0 0
COLOR 0 255 0
SIZE 15
MINSIZE 8
MAXSIZE 20
END
END
but the functions not found how say the documentation.=20
The problem is: $pt->draw($map, $layer, $image, 0, "Pt1") with style 1 =
because default is style 0.=20
Somebody know how solved?...I need help.=20
PD: Sorry by my english.
Daniel Lagos.
