Advanced DJVU to PNG conversion parameters

ImageResolutionH Integer

Set output image horizontal resolution in dpi.

ImageResolutionV Integer

Set output image vertical resolution in dpi.

ScaleImage Bool

Scale the output image. If ScaleImage is False output document will be stripped to ImageHeight / ImageWidth, if ScalePage is True output document will be scaled to ImageHeight / ImageWidth.

ScaleProportions Bool

Constrain proportions when scaling the output image.

ScaleIfLarger Bool

Scaling only if the input image is larger than the output.

ImageHeight Integer

Image height in pixels.

ImageWidth Integer

Image width in pixels.

TextAntialiasing Collection

Control the use of text subsample antialiasing. The subsampling box size should be 4 bits for optimum text antialiasing, but smaller values can be used for faster rendering.

Values: 0 1 2 4

GraphicsAntialiasing Collection

Control the use of graphics content subsample antialiasing. The subsampling box size should be 4 bits for optimum graphics content antialiasing, but smaller values can be used for faster rendering.

Values: 0 1 2 4

ImageInterpolation Bool

Specifies whether the image parser should use image interpolation. Enabling image interpolation will result in higher quality for scaled images at the expense of speed.

UseCIEColor Bool

Specifies whether the image parser should remap the device-dependent.
