Pdf/Page.php

Constructor signatures:

1. Load PDF page from a parsed PDF file.

Object factory is created by PDF parser.

new Zend_Pdf_Page(Zend_Pdf_Element_Dictionary $pageDict,

Zend_Pdf_ElementFactory_Interface $factory);

1. Clone PDF page. New page is created in the same context as source page. Object factory is shared. Thus it will be attached to the document, but need to be placed into Zend_Pdf::$pages array

to be included into output.

new Zend_Pdf_Page(Zend_Pdf_Page $page);

1. Create new page with a specified pagesize. If $factory is null then it will be created and page must be attached to the document to be

included into output.

new Zend_Pdf_Page(string $pagesize, Zend_Pdf_ElementFactory_Interface $factory = null);

1. Create new page with a specified pagesize (in default user space units). If $factory is null then it will be created and page must be attached to the document to be

included into output.

new Zend_Pdf_Page(numeric $width, numeric $height, Zend_Pdf_ElementFactory_Interface $factory = null);

Method signatures: drawEllipse($x1, $y1, $x2, $y2); drawEllipse($x1, $y1, $x2, $y2, $startAngle, $endAngle);

Method signatures: drawCircle($x, $y, $radius); drawCircle($x, $y, $radius, $fillType); drawCircle($x, $y, $radius, $startAngle, $endAngle); drawCircle($x, $y, $radius, $startAngle, $endAngle, $fillType);

It's not a really circle, because PDF supports only cubic Bezier curves. But very good approximation. It differs from a real circle on a maximum 0.00026 radiuses (at PI/8, 3PI/8, 5PI/8, 7PI/8, 9PI/8, 11PI/8, 13PI/8 and 15PI/8 angles). At 0, PI/4, PI/2, 3PI/4, PI, 5PI/4, 3PI/2 and 7*PI/4 it's exactly a tangent to a circle.

Method signatures: drawEllipse($x1, $y1, $x2, $y2); drawEllipse($x1, $y1, $x2, $y2, $fillType); drawEllipse($x1, $y1, $x2, $y2, $startAngle, $endAngle); drawEllipse($x1, $y1, $x2, $y2, $startAngle, $endAngle, $fillType);

If $fillType is Zend_Pdf_Page::SHAPE_DRAW_FILL_AND_STROKE or Zend_Pdf_Page::SHAPE_DRAW_FILL, then polygon is automatically closed. See detailed description of these methods in a PDF documentation (section 4.4.2 Path painting Operators, Filling)

Fill types: Zend_Pdf_Page::SHAPE_DRAW_FILL_AND_STROKE - fill rectangle and stroke (default) Zend_Pdf_Page::SHAPE_DRAW_STROKE - stroke rectangle Zend_Pdf_Page::SHAPE_DRAW_FILL - fill rectangle

Fill types: Zend_Pdf_Page::SHAPE_DRAW_FILL_AND_STROKE - fill rectangle and stroke (default) Zend_Pdf_Page::SHAPE_DRAW_STROKE - stroke rectangle Zend_Pdf_Page::SHAPE_DRAW_FILL - fill rectangle

radius is an integer representing radius of the four corners, or an array of four integers representing the radius starting at top left, going clockwise

$fontName should be specified in UTF-8 encoding

returns array of Zend_Pdf_Resource_Font_Extracted objects

This method is not intended to be used in userland, but helps to optimize some document wide operations

returns array of Zend_Pdf_Element_Dictionary objects

Be sure to consult the PDF reference to ensure your syntax is correct. No attempt is made to ensure the validity of the stream data.

This takes a snapshot of the currently applied style, position, clipping area and any rotation/translation/scaling that has been applied.

$alpha == 0 - transparent $alpha == 1 - opaque

Transparency modes, supported by PDF: Normal (default), Multiply, Screen, Overlay, Darken, Lighten, ColorDodge, ColorBurn, HardLight, SoftLight, Difference, Exclusion

Pattern is an array of floats: array(on_length, off_length, on_length, off_length, ...) Phase is shift from the beginning of line.
