font looks bolder in pdf than in AIR

[Mat]

I have a AIR application that renders a presentation. Now I need to
export this presentation into a PDF and use purePDF for this purpose.

The problem is the fontrendering. one of the fonts looks a lot bolder
in the pdf than if the application shows the presentation directly.

i embed and use the font for the realtime display like this:

[Embed(source="_embed/fonts/LT_54932.ttf", mimeType="application/x-
font", fontName="LightRegular", fontWeight="normal")] public var
LIGHT_REGULAR:Class;
then i create a new textformat and set myTextFormat.font to
"LightRegular" and apply it to my Textfield.

And the same font to be used in the pdf I embed and use like this:

[Embed(source="_embed/fonts/LT_54932.ttf", mimeType="application/octet-
stream")] public var LIGHT_REGULAR_FILE:Class;
...
FontsResourceFactory.getInstance().registerFont("lightRegular.ttf",
new LIGHT_REGULAR_FILE());
_lightRegularBf = BaseFont.createFont("lightRegular.ttf",
BaseFont.IDENTITY_H, BaseFont.EMBEDDED );
_textFont= new Font(-1, 12, -1, new RGBColor(0xae,0x0e,
0x1b),_lightRegularBf);


If I open the pdf and scale it to the same size as the AIR application
window, the font in the PDF looks a lot bolder.

Anyone knows what can be the reason for this?

We experienced some differences while rendering text with purePDF too.

The text looks bolder and worst for us chunks are a bit larger than the text rendered by flash and it could be cropped in the resulting PDF.

To prevent the text from being cropped we use a little trick :

We use the horizontalScaling property of the chunks like this :

var chunk:Chunk = new Chunk(spanText, font) ;

chunk.setHorizontalScaling(0.989);

This fix the crop issue but not fix the bolder font issue.

Please let me now if you've found a solution for that.

Thanks
