Opens a JPEG image (PHP 3 >= 3.0.9, PHP 4, PHP 5 <= 5.0.4)
bool cpdf_import_jpeg ( int pdf_document, string file_name, float x_coor, float y_coor, float angle, float width, float height, float x_scale, float y_scale, int gsave [, int mode] )

The cpdf_import_jpeg() function opens an image stored in the file with the name file_name. The format of the image has to be jpeg. The image is placed on the current page at position (x_coor, y_coor). The image is rotated by angle degrees. gsave should be non-zero to allow this function to operate correctly.

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。
