ConvertToBitonalDelegate Delegate

Apitron PDF Rasterizer help

Apitron.PDF.Rasterizer library for .NET

This delegate will be called if conversion to bitonal should be done by third-party software.

Namespace: Apitron.PDF.Rasterizer.Configuration
Assembly: Apitron.PDF.Rasterizer (in Apitron.PDF.Rasterizer.dll) Version: 3.0.154.0 (3.0.154.0)

Syntax

Copy

public delegate byte[] ConvertToBitonalDelegate(
	int width,
	int height,
	byte[] imageData,
	out int resultingWidth,
	out int resultingHeight
)

Public Delegate Function ConvertToBitonalDelegate ( 
	width As Integer,
	height As Integer,
	imageData As Byte(),
	<OutAttribute> ByRef resultingWidth As Integer,
	<OutAttribute> ByRef resultingHeight As Integer
) As Byte()

Parameters

width: Type: SystemInt32
The image width.
height: Type: SystemInt32
The image height.
imageData: Type: SystemByte
The image data array of bytes with pixel format BGRA8888(hence a pixel takes 4 bytes), the stride width would be width*4 in this case.
resultingWidth: Type: SystemInt32
The image width after conversion.
resultingHeight: Type: SystemInt32
The image height after conversion.

Return Value

Type: Byte
The pixel array that has bitonal format i.e one bit per pixel with padding for each image line.

Remarks

Bytes per line should be calculated by the formula: ((width & 0x07) != 0 ? (width >> 3) + 1 : width >> 3)

Remarks

Padding(in bits) might be calculated by the formula: BytesPerLine - width
