Re: Choosing the color of transparency ?

Hello Jie,

When creating a transparent image you should OR the CHART_TRANSPARENT

constant with a color so that we can use that color if the image format does

not support transparency (e.g. JPEG) or if the browser does not support


chart.RGBBk = CHART_TRANSPARENT Or RGB(192,192,192)
