如何在Qt GUI中显示原始图像文件？ [英] How to display a raw image file in a Qt GUI?

问题描述

我是C ++和Qt的新手，但我想知道是否有人可以帮助我。

I'm new to C++ and Qt but I was wondering if anyone could help me.

我有一个名为 fb0的原始图片文件具有以下属性：

I have a raw image file named fb0 with the following properties:

Width: 1024
Height: 768
Format: rgb565 (QImage::Format_RGB16?)

我如何从<$然后在Qt GUI中显示此图片？

How would I go about loading the data from fb0 and then displaying this image in a Qt GUI?

解决方案：

   QFile file("C:\\Users\\Username\\Desktop\\RawImage.raw");
   if (!file.open(QFile::ReadOnly))
   {
       qDebug("Could not open file");
   } else {
       qDebug() << file.fileName() << " opened";
   }
   QByteArray array =file.readAll();
   unsigned char* Data = (unsigned char*)&array.data()[0];
   QImage myImage(Data,1024,768,QImage::Format_RGB16);
   QLabel myLabel;
   myLabel.setPixmap(QPixmap::fromImage(myImage));
   myLabel.show();

推荐答案

您需要执行以下操作：

QFile file("yourFile.raw");
if (!file.open(QFile::ReadOnly)) return;
QByteArray array = file.readAll();
QImage image(array.data(), w, h, QImage::Format_RGB16);

尚未测试过。脑到终端。

Haven't tested it though. Brain to terminal.
