TImageEnIO.LoadFromFileJP2

Declaration

function LoadFromFileJP2(const FileName: WideString): Boolean;

Description

Loads an image from a Jpeg2000 (JP2) file.

FileName is the file name including extension.
Result will be false if the file is not JPEG2000 format (and Aborting will be true). Loading errors due to a file not being available will raise an exception.

Note:
◼ An optimized JPEG2000 library is used if the IELib or IEVision DLL is available
◼ You can abort loading by setting Aborting to true

Example

// Load a JPEG2000 image as fast as possible, ensuring width is >= 150 and height >= 100 (while maintaining the aspect ratio)
ImageEnView1.IO.Params.LoadToWidth  := 150;
ImageEnView1.IO.Params.LoadToHeight := 100;
ImageEnView1.IO.Params.J2000_Reduce := -1; // auto-calc
ImageEnView1.LoadFromFileJP2('image.jp2');
