PDFCanvas()
Creates a new instance of the graphics generator
|
| Modifier and Type | Method and Description |
|---|---|
void |
addRectangle(double x,
double y,
double width,
double height)
Adds a rectangle to the path
|
void |
close() |
void |
fillPath(int color)
Fills the current path and ends it
|
byte[] |
getResult()
Returns the generated graphics as a byte array
After this method was called, the page is no longer valid.
|
void |
lineTo(double x,
double y)
Adds a line segment to the open path from the previous point to the speicifed position.
|
void |
moveTo(double x,
double y)
Moves the current point of the open path to the specified position.
|
void |
putText(java.lang.String text,
double x,
double y,
int fontSize,
boolean isBold)
Adds text to the graphics.
|
void |
putTextLines(java.lang.String[] lines,
double x,
double y,
int fontSize,
double leading)
Adds several lines of text to the graphics.
|
void |
setTransformation(double translateX,
double translateY,
double scale)
Sets a translation and a scale factor for the subsequent operations
Before a new translation is applied, the coordinate system is
reset to it's original state after page setup (see
setupPage). |
void |
setupPage(double width,
double height)
Sets up the page
The page (and graphics context) is not valid until
this method has been called.
|
void |
startPath()
Starts a path that can be filled or stroked
|
void |
strokePath(double strokeWidth,
int color)
Strokes the current path and ends it
|
