TIEVisionLibrary.createImage
Declaration
function createImage(): TIEVisionImage; overload; safecall;
function createImage(width: int32_t; height: int32_t; channelFormat: TIEVisionChannelFormat; channels: int32_t): TIEVisionImage; overload; safecall;
function createImage(c: TIEVisionImage): TIEVisionImage; overload; safecall;
function createImage(filename: PAnsiChar): TIEVisionImage; overload; safecall;
function createImage(width: int32_t; height: int32_t; channelFormat: TIEVisionChannelFormat; channels: int32_t; rowlen: int32_t; data: pointer): TIEVisionImage; overload; safecall;
Description
First overload creates a new empty image object.
Second overload creates a new image object of the specified size and format.
Third overload creates a new image object from another
TIEVisionImage object.
Fourth overload creates a new image from the specified file. Currently supported file formats are: TIFF, JPEG, BMP, PNG, PXM, J2K (JPEG2000) and RAS.
Fifth overload creates a new image from the specified buffer (shares the same content). The buffer will be not released on destroy.

// create 1000x1000 RGB image
image := IEVisionLib.createImage(1000, 1000, ievUINT8, 3);
// load 'input.jpg'
image := IEVisionLib.createImage('input.jpeg');
// share ImageEnView1 bitmap
ImageEnView1.IEBitmap.Origin := ieboTOPLEFT;
image := IEVisionLib.createImage(ImageEnView1.IEBitmap.Width, ImageEnView1.IEBitmap.Height,
ievUINT8, 3, ImageEnView1.IEBitmap.Rowlen,
ImageEnView1.IEBitmap.ScanLine[0]);
// the same result of previous code
image := ImageEnView1.IEBitmap.GetIEVisionImage();
