AW: Rendering onto background image

[Burgwedel Friedrich]

I think you should use:

(pen.red (x) + background.red (4-x)) / 4

Try: 

(pen.red (x*x) + background.red (16-x*x)) / 16

This will sharpen the border between pen color and background color.

Betreff:   Rendering onto background image

Hi,

I previously posted a message regarding
rendering onto a background image and indicated
that, to blend,  I was using :

(pen.red( x) + background.red( 1-x)) /x

where x is the number in the glyph pixmap ( 0-4),
for each color component

I am acutally using

(pen.red( x) + background.red( 4-x)) /x

and getting results that are not as good as I would
like ( see attachment for example )

Any input would be appreciated,

Thanks,
John
