public enum DocumentImageOverTextMode

typedef NS_ENUM(NSInteger, LTDocumentImageOverTextMode) { 
 LTDocumentImageOverTextModeNone = 0,  
 LTDocumentImageOverTextModeStrict = 1,  
 LTDocumentImageOverTextModeRelaxed = 2 
};

public enum DocumentImageOverTextMode

[DataContractAttribute()] 
[SerializableAttribute()] 
public enum class DocumentImageOverTextMode

class DocumentImageOverTextMode(Enum): 
   None = 0 
   Strict = 1 
   Relaxed = 2

Members

Value	Member	Description
0	None	Apply no rules. The image will be used as is and no detection is perform.
1	Strict	The document writer will determine if the image is grayscale, if so, it will convert the image to black and white (1 bit per pixel) only if the image contains no grayscale values besides pure black and white.
2	Relaxed	The document writer will determine if the image is grayscale. If the image has noise or shadows, they will be ignored and the image is converted to black and white (1 bit per pixel).

Remarks

Use this option to control how the document writer converts the optional overlay image. Refer to PdfDocumentOptions.ImageOverTextSize and PdfDocumentOptions.ImageOverText for more information.

Currently this option is only used to determine when to convert grayscale overlay images to black and white in the final document. This is done to minimize the size of the output document.
