Detailed Description

Class definition of method frame for resizing of image.

The method frame is used when the resulting image has a different size than the operand image.

Constructor & Destructor Documentation

HxMfResize::HxMfResize (  HxImageData *    objImg,
HxSizes    newSize,
HxImageData *    argImg = 0
) 
 

Constructor.

Object() and result() will point to an empty image with the signature of objImg and the specified sizes. In case the signature of argImg is not equal to the signature of object() a temporary image with that signature will be created for argument() with the same pixel values as argImg. 

00017     : _object(objImg), _argument(argImg), _tmpArg(0)
00018 {
00019     if (!_object)
00020         return;
00021 
00022     HxImageSignature objSig(_object->signature());
00023 
00024     if (_argument) {
00025         HxImageSignature argSig(_argument->signature());
00026         if (!argSig.isEqual(objSig)) {
00027             _tmpArg = HxImgDataFactory::instance().makeImage(objSig, newSize);
00028             _tmpArg->set(_argument);
00029             _argument = _tmpArg;
00030         }
00031     }
00032 
00033     _result = HxImgDataFactory::instance().makeImage(objSig, newSize);
00034 //    if (_result)
00035 //        _result->set(_object);
00036     _object = _result;
00037 }
