UseTransparency

Boolean

Enables transparency drawing into the PDF file. PDFX can detect some drawing sequences and can then replace them with transparency drawing. Note that when PDF/A mode is used, this property is forced to False value. Default = True

NoTrans­parency.
See note below.

UseMaskedImages

Boolean

Using masked images produces smaller PDF files for some drawing sequences. Default = True

NoMasked
Images.
See note below.

GrayPaletteAsRGB

Boolean

If this option is enabled, the palettes of grayscaled images are stored as RGB palettes where each palette element has the same value for each of its RGB components. Default = False

(no V3)

ImagesOptimization

Boolean

Enables the optimization of image sequences. Such optimization requires many manipulations with images but causes the resulting PDF to be much smaller and better for viewing. Default = True

OptimizeImages

EnableSwapping

Boolean

Enables swapping images to the disk during image optimization. When swapping is turned off optimization time is smaller as a rule, but requires more memory. Default = True

SwapToDisk

SwapToDiskLimit

1-8

Defines the image size (in megabytes) in memory starting from which this image will be swapped to disk (if option EnableSwapping has True value). Default = 1

(no V3)
