Notes
|
Allows you to get or set the alpha opacity of the color. Alpha values can range from 0 to 255. Zero indicates fully transparent and 255 indicates fully opaque.
|
Example
|
Here we create a PDF document showing how different values of alpha result in different levels of transparency.
using var doc = new Doc();
doc.Rect.Inset(20, 20);
doc.FontSize = 300;
for (int i = 1; i <= 10; i++) {
doc.Color.Alpha = 255 / i;
doc.AddText(doc.Color.Alpha.ToString());
doc.Rect.Move(25, -50);
}
doc.Save("coloralpha.pdf");
