downsampleDPI
|
The size to which to downsample images
|
Number (default value 300)

|
downsampleMode
|
Algorithm for downsampling
When downsampleMode is set to a value other than off, and the DPI of an image is equal to or above the value of downsampleThreshold, the image is downsampled to downSampleDPI.
|
• off (default)
• subsample — fastest, uses nearest pixel from original image
The original image type will not be changed with this method.
• average — uses average of the group of pixels surrounding the nearest pixel from the original image
• bicubic — slowest but best quality, an enhanced bicubic algorithm
|

|
downSampleThreshold
|
The threshold size of an input image
|
Number (default value: 450)
|

|
quality
|
The amount of compression to apply to the images when printing to JPEG
|
• min
• low
• med (default)
• high
• max

|
• auto — use the most appropriate compression for the type of image
• none — do not compress
• flate (default) — Flate encoding
