Hi Alf, i've found a workaround
I was trying to print a Canvas with Text components inside, the scaleX
and scaleY properties haven't had any effect on canvas output but was
ok for the Text components. So, doing some maths I've changed the
canvas width and height, then i changed the scaleX and scaleY of Text
using a relation between the final and the previous canvas size.
var print:FlexPrintJob = new FlexPrintJob();
//making the canvas bigger
var pixelPerMilimeter:Number = 2.8333333;
var originalWidth:Number = this.myCanvas.width;
var originalHeight:Number = this.myCanvas.height;
var finalWidthPx:Number = this.finalHeightOnMilimeters *
pixelPerMilimeter;
var finalHeightPx:Number = this.finalWidthOnMilimeters *
pixelPerMilimeter;
this.myCanvas.height = altoCartelPx;
this.myCanvas.width = anchoCartelPx;
var relation:Number = finalWidthPx / originalWidth;
//i've found some margin problems with my printer, you can ignore this
var xd:Number = 0;
var yd:Number = 0;
if(this.papel2.width > this.papel2.height){ //horizontal
xd = 1.621443962;//3 / 1,850202703;
yd = 1.621443962;//3 / 1,850202703;
} else {
xd = 3 / 1.850202703;
yd = 3 / 1.850202703;
}
//making the Text components bigger
var ch:Array = this.papel2.getChildren();
for(var i:Number=0; i < ch.length; i++){
var tmp:UIComponent = UIComponent(ch[i]);
if(tmp != null){
//again this is for margins problems
tmp.x = tmp.x - (xd * relation);
tmp.y = tmp.y - (yd * relation);
//scale
tmp.scaleX = relation;
tmp.scaleY = relation;
tmp.validateNow();
}
}
this.myCanvas.validateNow();
//well, at this point we are finally ready to print
if(print.start()){
print.addObject(this.myCanvas,FlexPrintJobScaleType.NONE);
print.send();
}
notice that i'm using no scale for printing
I hope this helps you,
Claudio
