Prototype

ImgDelete(intImageHandle)

Description

It deletes an image from memory.

Parameters

intImageHandle: integer value corresponding to the image handle.

Returned value

None.

Notes

Its very important to use this function to remove from memory images allocated using other functions as ImgOpen or ImgCopy. After calling this function the image handle will be invalid and should be not used.


Example

//test if image is monochrome

nBits:=ImgGetBitsPixel(_CurrentImage);

//if it's not monochrome,

if nBits>1 then

begin

// copying  the whole image

BinaryImage:=ImgCopy(_CurrentImage,0,0,0,0);

//thresholding

ImgThreshold(BinaryImage,127);

//saving

NewFileName:=ExtractFilePath(_CurrentOutputFile)+'\Mono'+ExtractFileName(_CurrentOutputFile);

tipo:=ExtractFileExt(_CurrentOutputFile);

if tipo='.tif' then ImgSaveAsTif(BinaryImage,NewFileName)

else if tipo='.jpg' then ImgSaveAsJpg(BinaryImage,NewFileName)

else if tipo='.png' then ImgSaveAsPng(BinaryImage,NewFileName)

else if tipo='.bmp' then ImgSaveAsBmp(BinaryImage,NewFileName)

else ApplicationLog(_CurrentAgent,'Error: '+tipo+' format not supported in output.');

//deleting

ImgDelete(BinaryImage);

end;
