PdfGenerateConfig.MaximumDownscaleMultiplier Property
When DownscaleImages resizes an image, the resize target is the image’s on-page
display size multiplied by this value, clamped to never exceed the image’s natural decoded
size (downscaling never upscales). For example, an image displayed at 60x40 with a multiplier
of 2.0 resizes to 120x80 - useful headroom for zooming or printing. Defaults to
1.0 (resize to exactly the display size).
