Conversion parameters

ImageResolution Integer

Set output image 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.

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.

TransparentColor String

Add alpha channel to image, setting pixels matching color to transparent. Values accepted are RGBA, CMYK hex string, color name or RGB format like this 255,255,255 (RED=255, GREEN=255, BLUE=255) or 255,255,255,150 with alpha chanel.
