What is PhpDig?
PhpDig is a PHP MySQL based
Web Spider & Search Engine.



pdf_skew — Skew the coordinate system


bool pdf_skew(pdf, xangle, yangle);
resource pdf: PDF object identifier
double xangle: X skew angle
double yangle: Y skew angle


Always TRUE


Skews the coordinate system in the PDF document in the x and y axes by the specified angles. This is equivalent to what is normally known as shear, except that either axis can be affected.


Since version 4.0


Example 985. Skew a rectangle


// create new document
$pdf = pdf_new();
pdf_begin_page($pdf, 500, 700);

// draw new rectangle
pdf_rect($pdf, 50, 50, 100, 20);

// skew drawing
pdf_skew($pdf, 10, 10);

// draw rectangle with skew
pdf_rect($pdf, 100, 100, 100, 20);


// output document
$data = pdf_get_buffer($pdf);
header("Content-type: application/pdf");
header("Content-disposition: inline; filename=test.pdf");
header("Content-length: " . strlen($data));
echo $data;
