好吧,(假设您正确获取像素数据)您必须将创建的纹理分配给某些东西......
我会使用例如RawImage,因为它不需要 a Sprite(就像UI.Image组件一样 - 另请参阅RawImage Manual):
// Reference this in the Inspector
public RawImage image;
//...
pcxFile = File.ReadAllBytes("Assets/5_ImageParser/bagit_icon.pcx");
int startPoint = 128;
int height = 152;
int width = 152;
target = new Texture2D(height, width);
for (var y = 0; y < height; y++)
{
for (var x = 0; x < width; x++)
{
timesDone ++;
pixels[x, y] = new Color(pcxFile[startPoint], pcxFile[startPoint+1], pcxFile[startPoint+2]);
startPoint += 4;
target.SetPixel(x, y, pixels[x, y]);
}
}
target.Apply();
// You don't need this. Only if you are also going to save it locally
// as an actual *.jpg file or if you are going to
// e.g. upload it later via http POST
//
// In this case however you would have to asign the result
// to a variable in order to use it later
//var rawJpgBytes = target.EncodeToJPG();
// Assign the texture to the RawImage component
image.texture = target;
或者,与普通Image组件一起使用Sprite从您的纹理创建一个Sprite.Create:
// Reference this in the Inspector
public Image image;
// ...
var sprite = Sprite.Create(target, new Rect(0.0f, 0.0f, target.width, target.height), new Vector2(0.5f, 0.5f), 100.0f);
image.sprite = sprite;
提示 1
为了获得正确的纵横比,我通常使用一个小技巧:
为这个 RawImage 创建一个父对象
RectTransform在父级中设置所需的“最大尺寸”
RawImage在/旁边Image(在子对象上)添加一个AspectRatioFitter(另见AspectRatioFitter Manual)并设置AspectMode为FitInParent.
现在在代码中调整纵横比(从纹理中获取):
public RawImage image;
public AspectRatioFitter fitter;
//...
image.texture = target;
var ratio = target.width / target.height;
fitter.aspectRatio = ratio;
提示 2对所有像素调用一次比重复
调用“便宜” :SetPixelsSetPixel
// ...
startPoint = 0;
pixels = new Color[width * height]();
for(int i = 0; i < pixels.Length; i++)
{
pixels[i] = new Color(pcxFile[startPoint], pcxFile[startPoint+1], pcxFile[startPoint+2]);
startPoint += 4;
}
target.SetPixels(pixels);
target.Apply();
// ...
(我不知道您的pcx格式究竟是如何工作的,但也许您甚至可以使用LoadRawTextureData
