PointUtil

public PointUtil()

Method Details

convertPathAbbreviatedDatatoPoint

public static List<PathPoint> convertPathAbbreviatedDatatoPoint(String abbreviatedData)

解析压缩路径为点坐标

Parameters:

abbreviatedData - 压缩路径

Returns:

绘制点坐标序列

calPathPoint

public static List<PathPoint> calPathPoint(List<PathPoint> abbreviatedPoint)

calTextPoint

public static List<TextCodePoint> calTextPoint(List<org.ofdrw.core.text.TextCode> textCodes)

adjustPos

public static double[] adjustPos(double width,
 double height,
 double x,
 double y,
 org.ofdrw.core.basicType.ST_Box boundary)

combineBoundary

public static org.ofdrw.core.basicType.ST_Box combineBoundary(org.ofdrw.core.basicType.ST_Box parentBoundary,
 org.ofdrw.core.basicType.ST_Box childBoundary)

将子图元的外接矩形转换到父图元坐标系。

Parameters:

parentBoundary - 父图元外接矩形

childBoundary - 子图元在父图元坐标系中的外接矩形

Returns:

子图元在页面坐标系中的外接矩形

ctmCalPoint

public static double[] ctmCalPoint(double x,
 double y,
 Double[] ctm)

isLegacyAbsolutePath

public static boolean isLegacyAbsolutePath(double width,
 double height,
 org.ofdrw.core.basicType.ST_Box boundary,
 List<PathPoint> points,
 boolean hasCtm,
 org.ofdrw.core.basicType.ST_Array ctm)

Detects the absolute 300 DPI path coordinates used by pre-standard Foxit OFD files. Their declared CTM places the complete path outside its Boundary, while interpreting the raw coordinates as 300 DPI device coordinates places it inside the Boundary.

calPdfPathLineWidth

public static double calPdfPathLineWidth(double lineWidth,
 double scale,
 boolean legacyAbsolutePath,
 org.ofdrw.core.basicType.ST_Array ctm)

Converts an OFD path line width to PDF points.
