cpdf_arc -- Draws an arc

Description

bool cpdf_arc ( int pdf_document, float x_coor, float y_coor, float radius, float start, float end [, int mode] )

The cpdf_arc() function draws an arc with center at point (x_coor, y_coor) and radius radius, starting at angle start and ending at angle end. 如果成功则返回 TRUE，失败则返回 FALSE。

可选参数 mode 决定单元的长度。如果为 0 或被省略则使用该页指定的默认单元。否则坐标忽略当前单元而使用 postscript 的点来度量。
