示例1: resizeInput
void resizeInput(vector<char> &jpgdata, int maxDim){
// Takes the buffer containing encoded jpg, determines if its shortest dimension
// is greater than maxDim. If so, it scales it down so that the shortest dimension
// is equal to maxDim. equivalent to "512x512^>" for maxDim=512 geometry argument in
// imagemagick
Mat image(1, jpgdata.size(), CV_8UC3, &jpgdata[0]);
Mat decodedImage = cv::imdecode(image, CV_LOAD_IMAGE_COLOR);
int minDim = std::min(decodedImage.rows, decodedImage.cols);
// If no resizing necessary, just return, original image still in jpgdata;
if (minDim <= maxDim)
return;
vector<int> param = {CV_IMWRITE_JPEG_QUALITY, 90};
double scaleFactor = (double) maxDim / (double) minDim;
Mat resizedImage;
cv::resize(decodedImage, resizedImage, Size2i(0, 0), scaleFactor, scaleFactor, CV_INTER_AREA);
cv::imencode(".jpg", resizedImage, *(reinterpret_cast<vector<uchar>*>(&jpgdata)), param);
return;
}示例2: getSize
const Size2i getSize() {
return Size2i(_width, _height);
