Property Documentation

CompressionCode Compression[get, set]

Gets the type of compression to be used in saving the image to a file.

bool DisableAlphaChannelGeneration[get, set]

Gets whether alpha channel generation is disabled for the output image.

When false, RGB image data with a Mask will be combined as RGBA + Alpha Channel output (32-bit). When true, the Mask is not combined and the output is RGB (24-bit). This is only valid for TIFF and PNG output formats.

bool HalftoneGrayImages[get, set]

Gets whether grayscale images are converted to halftone.

When true, converts 8bpc grayscale images to 1bpc (B/W) images using a 45 degree line screen set for 106lpi at 600dpi. Note this can only be set to true for an image of ColorSpace of DeviceGray.

int JPEGQuality[get, set]

Gets the quality of a JPEG output image.

byte MonochromeThreshold[get, set]

Gets the threshold for determining which bits are white or black for Monochrome output.

Note: this is only valid for TIF Images using G3 or G4 compression and HalftoneGrayImages must be set to false.

bool RaiseExceptionIfNotUsableColor[get, set]

Gets whether an exception is raised if the image color format is not natively supported.

When true, an exception will be raised if the image being saved is not in a format this graphic form can save natively. When false, the image will be automatically converted into a form that can be saved natively (generally DeviceRGB using the sRGB profile).

bool ReverseGray[get, set]

Gets whether the GrayScale output is reversed.

Note this is only valid for an image with a DeviceGray Colorspace.

bool TIFFBlackIsOne[get, set]

Gets whether a TIFF file is photometrically reversed.

Note this is only valid for a 1-bit TIFF image with a DeviceGray Colorspace.

TIFFByteOrder TIFFByteOrder[get, set]

Gets the byte order used within the TIFF file.

This is only valid for TIFF output.

bool TIFFCMYKAlpha[get, set]

Gets whether CMYK image data is combined with the Soft Mask in TIFF output.

Note: This is only valid for CMYK image data which has a Soft Mask; the output will be 40-bit.

bool WriteSeparationColorsToTIFF[get, set]

Gets whether separation colors are written to TIFF using the Photoshop tag.

When false, separation colors will be converted to their alternate color space and rendered as RGB. When true, separation colors are output using the TIFF Photoshop tag.
