Parameter Description
Layer Drawing Options

Antialiasing Quality: Smoothness setting applied to colour art. The higher the setting, the greater the amount of antialiasing applied. Higher quality images require more time to render and more system memory. Choose a lower quality if you are rendering a pencil test.

Low: No antialiasing
Medium Low: Some antialiasing
Medium: Medium antialiasing
High: Extensive antialiasing

Antialiasing Exponent: Controls the amount of area around the Line and Colour Art edges used in the antialiasing process. A higher value uses less area, resulting in sharper edges, while a lower value uses more area, resulting in softer edges. If the Antialiasing Quality value is set to Low (no antialiasing), this value is ignored.

Read Colour: Reads colour information from bitmap images. If this node reads 3 or 4-channel bitmaps, this selection determines whether the colour should be read or ignored. If this node reads 1-channel bitmaps, this selection determines whether the channel should be read as colour. When this option is selected with 1-channel images, the resulting image will be a greyscale image.

Read Transparency: Reads the alpha information from bitmap images. If this node reads a 1 or 3-channel image, this option will create a matte from the colour values in the image. If the node reads a 4-channel image and this option is not selected, the alpha information in the image will be ignored.

Alignment Rule: The Alignment position for the element node. The new element node will be created following this default rule of alignment.

Transparency Type:

Premultiplied with Black: Pixels at the edge of an image are blended with black.
Straight: Pixels at the edge of an image are blended with black, white and greys.
Premultiplied with White: Pixels at the edge of an image are blended with white.
Clamp Colour to Alpha: Select this option when you want to premultiply the colour value with the alpha value. When the colour is clamped to the alpha, the colour value cannot be higher than the alpha value. It calculates the real colour value faster. When the RGB values are multiplied with the alpha value, that is, if you have a pixel of value R=247, G=188, B=29 and the alpha is 50% or the image has a 50% transparency, then the actual RGB values output would be half the amounts listed above.

Art Layer Options:

Overlay Art, Line Art, Colour Art, Underlay Art

Vector/Bitmap: Determines if a newly created element will have this layer as vector or bitmap.
