Notes
|
Adds a separation color space to the document returning the ID of the newly added object. Separation color spaces allow you to add spot colors or isolate the use of individual colorants. A separation color space represents a particular colorant and allows you to specify the amount of that colorant that is applied. For example you might define a separation color space called Gold with a display representation of CMYK yellow. You might then draw some text with different amounts of Gold. When viewing the output on a standard monitor the display representation of the color would be used. However when printed - using appropriate software and an appropriate printer - the name of the color might be used to select a gold colored ink. The current color space is defined by the ColorSpace property. The current color is defined by the Color property. Because separations represent a single value property you should use single component - grayscale - colors to specify the amount of spot colorant to use. There are two special color spaces: 'All' refers collectively to all colorants on an output device. It can be useful for printing registration marks. 'None' indicates no colorant and will never produce any visible output.

Example
|
In this example we define a colorant called Gold and add some text using varying amounts of our colorant.
using (Doc doc = new Doc()) {
doc.Rect.Inset(20, 20);
doc.FontSize = 300;
doc.ColorSpace = doc.AddColorSpaceSpot("GOLD", "0 0 100 0");
for (int i = 1; i <= 10; i++) {
doc.Color.Gray = 255 / i;
doc.AddText(doc.Color.Gray.ToString());
doc.Rect.Move(25, -50);
}
doc.Save(Server.MapPath("docaddcolorspacespot.pdf"));
}
