TImageEnMIO.LoadFromFilePDF

Declaration

function LoadFromFilePDF(const FileName: string; Width: Integer = -1; Height: Integer = -1; const Password: string = ''): Boolean;

Description

Loads a PDF image or a multipage PDF into the attached TImageEnMView or TIEMultiBitmap using a plug-in.
You can optionally specify a size to load the PDF file to improve quality (the size will be automatically adjusted to maintain the aspect ratio).
If the file is encrypted you can specify the password (otherwise a password prompt will be displayed if AutoPromptForPassword is enabled).
Result will be false if the file is not PDF format or no PDF plug-ins are available (Aborting will be true). Loading errors due to a file not being available will raise an exception.

PDF loading requires one of the following plug-ins:
◼ImageEn PDFium Plug-in from: www.imageen.com/download/
◼WPViewPDF commercial plug-in
◼ImageMagick + GhostScript


Note:
◼PDF loading creates a rasterized image of each page
◼LoadFromFilePDF is not compatible with SaveToFilePDF. If you save a file using this method each PDF page will be an image (e.g. text cannot be selected)
◼Existing content is not cleared. Call Clear to remove existing content before loading
◼To abort while loading set Aborting to true
