Summary
Initializes a new DotRemoveCommand with explicit parameters.
Syntax
C#
Objective-C
C++/CLI
Java
Python
- (instancetype)initWithFlags:(LTDotRemoveCommandFlags)flags minimumDotWidth:(NSInteger)minimumDotWidth minimumDotHeight:(NSInteger)minimumDotHeight maximumDotWidth:(NSInteger)maximumDotWidth maximumDotHeight:(NSInteger)maximumDotHeight NS_DESIGNATED_INITIALIZER; 
public DotRemoveCommand( 
   int flags,  
   int minimumDotWidth,  
   int minimumDotHeight,  
   int maximumDotWidth,  
   int maximumDotHeight 
) 
__init__(self,flags,minimumDotWidth,minimumDotHeight,maximumDotWidth,maximumDotHeight) # Overloaded constructor 

Parameters

flags
Flag that determines the behavior of the dot removal process.

minimumDotWidth
The minimum width of a dot to be removed. If the DotRemoveCommandFlags.UseDpi flag is set, units are in thousandths of an inch, otherwise units are in pixels.

minimumDotHeight
The minimum height of a dot to be removed. If the DotRemoveCommandFlags.UseDpi flag is set, units are in thousandths of an inch, otherwise units are in pixels.

maximumDotWidth
The maximum width of a dot to be removed. If the DotRemoveCommandFlags.UseDpi flag is set, units are in thousandths of an inch, otherwise units are in pixels.

maximumDotHeight
The maximum height of a dot to be removed. If the DotRemoveCommandFlags.UseDpi flag is set, units are in thousandths of an inch, otherwise units are in pixels.

Example

Run the DotRemoveCommand on an image.
