是否可以根据我想要的形状裁剪捕获的图像?我正在使用原始图像 + 网络摄像头纹理来激活相机并保存图像。我使用 UI Image 叠加方法作为掩码来覆盖不需要的部分。我将在后半部分将图片附加到 char 模型中。对不起,我是统一的新手。感谢您的帮助!
以下是我的代码中的内容:
// start cam
void Start () {
devices = WebCamTexture.devices;
background = GetComponent<RawImage> ();
devCam = new WebCamTexture ();
background.texture = devCam;
devCam.deviceName = devices [0].name;
devCam.Play ();
}
void OnGUI()
{
GUI.skin = skin;
//swap front and back camera
if (GUI.Button (new Rect ((Screen.width / 2) - 1200, Screen.height - 650, 250, 250),"", GUI.skin.GetStyle("btn1"))) {
devCam.Stop();
devCam.deviceName = (devCam.deviceName == devices[0].name) ? devices[1].name : devices[0].name;
devCam.Play();
}
//snap picture
if (GUI.Button (new Rect ((Screen.width / 2) - 1200, Screen.height - 350, 250, 250), "", GUI.skin.GetStyle ("btn2"))) {
OnSelectCapture ();
//freeze cam here?
}
}
public void OnSelectCapture()
{
imgID++;
string fileName = imgID.ToString () + ".png";
Texture2D snap = new Texture2D (devCam.width, devCam.height);
Color[] c;
c = devCam.GetPixels ();
snap.SetPixels (c);
snap.Apply ();
// Save created Texture2D (snap) into disk as .png
System.IO.File.WriteAllBytes (Application.persistentDataPath +"/"+ fileName, snap.EncodeToPNG ());
}
}
