Name

pdf_add_thumbnail — Add an image as a thumbnail for the current page.

Synopsis

bool pdf_add_thumbnail(pdf, image); resource pdf: PDF object identifier int image: Image identifier

Returns

Always TRUE

Description

Creates a thumbnail which appears in the thumbnail pane of most Acrobat readers. The image parameter is an image handler returned from pdf_open_image() or pdf_open_image_file() .

The thumbnail image must be no greater than 106x106 pixels in size and must be either a greyscale, rgb or rgb indexed file. Adding a thumbnail does not make a snapshot of the page itself but merely inserts an image as a thumbnail.

In the example below, note how the thumbnails pane is automatically opened using pdf_set_value() .

Version
