示例1: doRoi
import javax.media.opengl.GL2; //導入方法依賴的package包/類
@Override protected void doRoi() {
transformer.transform(srcRoiPts, dstRoiPts, parameters, false);
double[] pts = dstRoiPts.get();
for (int i = 0; i < pts.length; i++) {
pts[i] /= (1<<pyramidLevel);
}
roi.x(0).y(0).width(maskCL[pyramidLevel].width).height(maskCL[pyramidLevel].height);
// Add +3 all around because cvWarpPerspective() needs it for interpolation,
// and there seems to be something funny with memory alignment and
// ROIs, so let's align our ROI to a 16 byte boundary just in case..
JavaCV.boundingRect(pts, roi, 3, 3, 16, 1);
//System.out.println(roi);
inputData.roiX = roi.x();
inputData.roiY = roi.y();
inputData.roiWidth = roi.width();
inputData.roiHeight = roi.height();
// GLContext glContext = context.getGLContext();
// glContext.makeCurrent();
GL2 gl = context.getGL2();
