Initializes with DeviceRGB color space, no smoothing, zero pixel dimensions, 300 dpi resolution, relative colorimetric render intent, and black point compensation enabled.

PageImageParams(ColorSpace ColorSpace, SmoothFlags Smoothing, int PixelWidth, int PixelHeight, double HorizontalResolution, double VerticalResolution, DrawFlags PageDrawFlags)

Parameters

ColorSpace: ColorSpace: The desired color space for the image, DEVICERGB, DEVICECMYK or DEVICEGRAY only.
Smoothing: SmoothFlags: Indicates what parts of PDF Page (text, image, art, none) are to be smoothed in rendering to an image. Note these flags can be or'd together
PixelWidth: int: The desired witdth in pixels of the output image.
PixelHeight: int: The desired height in pixels of the output image.
HorizontalResolution: double: The desired horizontal resolution in pixels/inch of the output image. If you pass in 0.0, 300.0 dpi is used.
VerticalResolution: double: The desired vertical resolution in pixels/inch of the output image. If you pass in 0.0, 300.0 dpi is used.
