Openhtmltopdf 1.0.10 · com.openhtmltopdf.util.DownscaleQuality

Simple enumerated constants for downscaling (scaling to smaller image size)--since we have various options for what algorithm to use. Not general-purpose, applies only to methods used in ImageUtil. Types constants can be looked up using forString(String, DownscaleQuality) and the corresponding string for the quality

Field Summary

Modifier and Type	Field and Description
public static final DownscaleQuality	AREA One step, fast, but should be better than low-quality.
private static Map<String, DownscaleQuality>	constList Internal map string type to DQ instance
public static final DownscaleQuality	FAST Low quality, but very fast.
public static final DownscaleQuality	HIGH_QUALITY Highest-quality downscaling; probably slowest as well.
public static final DownscaleQuality	LOW_QUALITY Low-quality, but not worst quality
