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 (Nothing in Visual Basic) to dither to the fixed palette or if no palette is required.

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(Int32,Int32,Byte[],Int32,Int32) to retrieve the resized data and by a call to Stop, to end the resize process and clean up any allocated resources.
