QString str;

str.setNum(src1->width);

ui->lineEdit->setText(str);

}

cvReleaseImage(&src1);

}

void Widget::on_pushButton_clicked()

{

bool ok;

double alpha,beta,temp;

int x,y,width,height;

temp = ui->lineEdit_7->text().toDouble(&ok);

if (ok)

{

}

else

{

}

cout << alpha << endl;

temp = ui->lineEdit_8->text().toDouble(&ok);

if (ok)

{

}

else

{

beta = 0.6;

}

cout << beta << endl;

x= ui->lineEdit_5->text().toInt(&ok,10);

cout << x << endl;

cvSetImageROI(src1,cvRect(x,y,width,height));

cvSetImageROI(src2,cvRect(x,y,width,height));

cvSetImageROI(dst,cvRect(x,y,width,height));

cvAddWeighted(src1,alpha,src2,beta,0.0,dst);

cvResetImageROI(src1);

cvResetImageROI(src2);

cvResetImageROI(dst);

cvShowImage("jdh1",src1);
