pub const MIN_IMAGE_DPI: f32 = 1.0;Expand description
Lower bound applied to any requested image DPI. A non-positive request would produce a zero/negative downsample target, so it is clamped up to this floor.
Public alongside DEFAULT_IMAGE_DPI because RenderOptions::with_image_dpi
silently clamps to it: a caller passing 0.0 gets this value back, and
without the constant there is no way to predict or detect that from outside
the crate.
