I was looking for the same answer and your question actually put me on the right track.
From inspecting the TCPDF class, ended up finding the answer in the TCPDF_STATIC class, in the static method TCPDF_STATIC::getPageLayoutMode().
The correct function to use would be TCPDF::SetDisplayMode($zoom, $layout, $mode). For your purpose I'd suggest:
$pdf->SetDisplayMode('default','OneColumn'); OR $pdf->SetDisplayMode('default','continuous'); // continuous not documented, although should work.
Possible values for those parameters are as follows (from the method's PHPdoc):
- $zoom
The zoom to use. It can be one of the following string values or a number indicating the zooming factor to use.- fullpage: displays the entire page on screen
- fullwidth: uses maximum width of window
- real: uses real size (equivalent to 100% zoom)
- default: uses viewer default mode
- $layout
The page layout. Possible values are:- SinglePage Display one page at a time
- OneColumn Display the pages in one column
- TwoColumnLeft Display the pages in two columns, with odd-numbered pages on the left
- TwoColumnRight Display the pages in two columns, with odd-numbered pages on the right
- TwoPageLeft (PDF 1.5) Display the pages two at a time, with odd-numbered pages on the left
- TwoPageRight (PDF 1.5) Display the pages two at a time, with odd-numbered pages on the right
- $mode
A name object specifying how the document should be displayed when opened:- UseNone Neither document outline nor thumbnail images visible
- UseOutlines Document outline visible
- UseThumbs Thumbnail images visible
- FullScreen Full-screen mode, with no menu bar, window controls, or any other window visible
- UseOC (PDF 1.5) Optional content group panel visible
- UseAttachments (PDF 1.6) Attachments panel visible
public function SetDisplayMode($zoom, $layout='SinglePage', $mode='UseNone') { if (($zoom == 'fullpage') OR ($zoom == 'fullwidth') OR ($zoom == 'real') OR ($zoom == 'default') OR (!is_string($zoom))) { $this->ZoomMode = $zoom; } else { $this->Error('Incorrect zoom display mode: '.$zoom); } $this->LayoutMode = TCPDF_STATIC::getPageLayoutMode($layout); $this->PageMode = TCPDF_STATIC::getPageMode($mode); }
