Start Method

Summary

Sets up information for the ResizeBuffer method.

Syntax

C++

public void Start( 
   RasterImage image, 
   int width, 
   int height, 
   int bitsPerPixel, 
   RasterByteOrder order, 
   RasterDitheringMethod ditheringMethod, 
   RasterSizeFlags sizeFlags, 
   RasterColor[] palette 
)

Public Sub Start( _ 
   ByVal image As RasterImage, _ 
   ByVal width As Integer, _ 
   ByVal height As Integer, _ 
   ByVal bitsPerPixel As Integer, _ 
   ByVal order As RasterByteOrder, _ 
   ByVal ditheringMethod As RasterDitheringMethod, _ 
   ByVal sizeFlags As RasterSizeFlags, _ 
   ByVal palette() As RasterColor _ 
)

public: 
void Start(  
   RasterImage^ image, 
   int width, 
   int height, 
   int bitsPerPixel, 
   RasterByteOrder order, 
   RasterDitheringMethod ditheringMethod, 
   RasterSizeFlags sizeFlags, 
   array<RasterColor>^ palette 
)

Parameters

image
Image to be resized.

width
New width of the image data.

height
New height of the image data.

bitsPerPixel
Output bits per pixel. Use 0 for 8-bit grayscale. Possible values are: 0, 1, 2, 3, 4, 5, 6, 7, 8, 12, 16, 24, 32, 48 and 64.

order
Output color order.

ditheringMethod
Flags that indicate the type of dithering, if bitsPerPixel is not the same as the source image.

sizeFlags
Flags that indicate the type of resizing.

palette
The palette to dither to if bitsPerPixel is less than or equal to 8. Pass a null reference to dither to the fixed palette or if no palette is required.

Remarks

ditheringMethod is used when dithering is needed to produce the output bits per pixel. The interpolation usually requires that the input data be converted to 24-bit or 48-bit and then back to the desired bits per pixel. So some dithering might be required if the output bits/pixel are less than or equal to 8.

The Start method starts the resizing process. This will be followed by calls to ResizeBuffer to retrieve the resized data and by a call to Stop, to end the resize process and clean up any allocated resources.
