TImageEnIO.LoadFromFileZIP

TImageEnIO.LoadFromFileZIP


Declaration

function LoadFromFileZIP(const FileName: string; FileIndex: Integer = -1; const Password: string = ''): Boolean;


Description

Loads an image from a ZIP file into the attached TImageEnView or TIEBitmap using a plug-in.
If FileIndex = -1, then ImageIndex will be used to specify which page of the ZIP file to load.
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 ZIP format or no ZIP plug-ins are available (Aborting will be true). Loading errors due to a file not being available will raise an exception.



Note:
ZIP extraction requires the 7z plug-in from: www.imageen.com/download/
FileName can include the full path to a file within the zip (instead of specifying a file index), e.g. C:\Folder\MyZip.zip\Path\image.jpeg
