pdf_begin_pattern

Name

pdf_begin_pattern — Start a new pattern definition.

Synopsis

int pdf_begin_pattern(pdf, width, height, xstep, ystep, painttype);
resource pdf: PDF object identifier
double width: Bounding box width
double height: Bounding box height
double xstep: X offset
double ystep: Y offset
int painttype: Color setting

Returns

Pattern identifier

Description

Starts a pattern definition which cab be used to to fill or stroke objects instead of a color. The function returns a pattern identifier which is used in pdf_setcolor() to set the fill and/or stroke of an object to the defined pattern. Note that the pattern definition must be before pdf_begin_page() .

Normally. applications set xstep and ystep to width and height of the pattern so results may vary slightly from application to application.

If painttype is 1, then the pattern must contain it's own color specification which also allows more freedom since you can use functions like pdf_setcolor() in the pattern definition itself. However, you cannot load images to use in the pattern. If painttype is 2 then the current fill or stroke color is applied to the object.

Version

Since version 4.0.5

Example

Example 916. Create two fill patterns

<?php
$pdf = pdf_new();
pdf_open_file($pdf);

// create first pattern
$pattern1 = pdf_begin_pattern($pdf, 20, 20, 10, 10, 2);
   pdf_circle($pdf, 10,10,10);
   pdf_stroke($pdf);
pdf_end_pattern($pdf);

// defined second pattern with own colorspace
$pattern2 = pdf_begin_pattern($pdf, 20, 20, 10, 10, 1);
   pdf_setcolor($pdf, "stroke", "rgb", 0.9, 0.1, 0.1, 0.0);
   pdf_circle($pdf, 7, 7, 5);
   pdf_stroke($pdf);
   pdf_setcolor($pdf, "stroke", "rgb", 0.1, 0.9, 0.9, 0.0);
   pdf_circle($pdf, 5, 5, 10);
   pdf_stroke($pdf);
pdf_end_pattern($pdf);

pdf_begin_page($pdf, 500, 700);

// set color to the first pattern
pdf_setcolor($pdf, "fill", "pattern", $pattern1, 0.0, 0.0, 0.0);
pdf_rect($pdf, 30, 640, 180, 30);
pdf_fill($pdf);

// set color to the second pattern
pdf_setcolor($pdf, "fill", "pattern", $pattern2, 0.0, 0.0, 0.0);
pdf_rect($pdf, 30, 500, 350, 100);
pdf_fill($pdf);

pdf_end_page($pdf);
pdf_close($pdf);

// display the PDF 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;
?>
