Class: writer  - X-Ref

pdf data format writer

__construct()   X-Ref
writer constructor.


send_http_headers()   X-Ref
No description

start_output_to_file()   X-Ref
Start output to file, note that the actual writing of the file is done in {@see close_output_to_file()}

supports_html()   X-Ref
Method to define whether the dataformat supports export of HTML

return: bool

export_html_image_source(\stored_file $file)   X-Ref
When exporting images, we need to return their Base64 encoded content. Otherwise TCPDF will create a HTTP
request for them, which will lead to the login page (i.e. not the image it expects) and throw an exception

Note: ideally we would copy the file to a temp location and return it's path, but a bug in TCPDF currently
prevents that

param: \stored_file $file
return: string|null

write_record($record, $rownum)   X-Ref
Write a single record

param: array $record
param: int $rownum

close_output()   X-Ref

return: bool

print_heading(\pdf $pdf)   X-Ref
