Compression_Default | Use the default for the output image type.
|
Compression_NONE | Use no image compression. Valid for BMP, PNG and TIFF outputs only.
|
Compression_FLATE | Deflate algorithm (PNG only). An open source standard widely used for creating zip files and with PDF.
|
Compression_LZW | Lempel-Ziv-Welch, valid for TIFF output. A lossless algorithm, resulting files are larger but retain original quality.
|
Compression_G3 | CCITT Group3 compression. Valid for TIFF, requires colorModel gray. A lossless algorithm for black and white images that efficiently compresses whitespace.
|
Compression_G4 | CCITT Group4 compression. Valid for TIFF, requires colorModel gray. A lossless algorithm for black and white images based on G3.
|
Compression_DCT | Discrete Cosine Transform. Lossy algorithm, valid for JPEG. Best when used with continuous tone (such as photographs).
|
Order_BigEndian=0 | |
Order_LittleEndian=1 | |
HostEndian=2 |
| |
Default: false. Convert 8bpc grayscale images to 1bpc (B/W) images using a 45 degree line screen set for 106lpi at 600dpi.
| |
Default: 75. Quality of the image(0-100). Note this is only valid for JPEG Images.
| |
Default: 72. This value sets the image's Horizontal DPI (Dots Per Inch), which will be used during the exporting process.
| |
Default: 72. This value sets the image's Vertical DPI (Dots Per Inch), which will be used during the exporting process.
| |
Default: Default. Type of compression to be used in saving the image to a file. Note this is only valid for TIF Images.
| |
Default: 128. Threshold to use for determining which bits are white or black for Monochrome output(0-255). This is only valid for TIF Images using G3 or G4 compression and HalftoneGrayImages must be set to false.
| |
Default: false. When set to false, if the image data is in RGB and there is a Mask present, they will be combined as RGBA + Alpha Channel output (32-bit). When set to true, if the image date is in RGB and there is a Mask present, they will not be combined and the output will be RGB (24-bit). This is only valid for an output image of type TIF and PNG.
| |
Default: BigEndian. The byte order used within the TIFF file.
