Dynamic LiveTile - 通过后台任务在 LiveTile 上渲染自定义字体 TextBlock
我在 liveTile 上使用自定义字体资源渲染自定义文本块时遇到问题？
我的项目在后台更新动态磁贴。但它应该是个性化的。
我正在使用这个代码。但它不起作用，当我尝试使用嵌入字体时，文本显示为空白 位图背景效果很好。但字体不起作用。
当我在“前台代理”中使用相同的代码时，字体显示完美。
Grid grid = new Grid();
// load your image
StreamResourceInfo info = Application.GetResourceStream(new Uri("tile.jpg", UriKind.Relative));
// create source bitmap for Image control (image is assumed to be alread 173x173)
WriteableBitmap wbmp2 = new WriteableBitmap(1, 1);
wbmp2.SetSource(info.Stream);
Image img = new Image();
img.Source = wbmp2;
// add Image to Grid
grid.Children.Add(img);
TextBlock text = new TextBlock()
{
FontFamily = new FontFamily("/MyTaskAgent;component/Fonts/Fonts.zip#Buxton Sketch"),
Foreground = new SolidColorBrush(Colors.Black) ,
TextWrapping = TextWrapping.Wrap,
};
text.Text = "Test";
// this is our final image containing custom text and image
WriteableBitmap wbmp = new WriteableBitmap(173, 173);
// now render everything - this image can be used as background for tile
wbmp.Render(grid, null);
wbmp.Invalidate();
I'm having problems in rendering custom textblock with custom font resource on liveTile ?
My project updates a live tile in background. but it should be personalized.
Im using this code. but its does not woks, the text shows blank when i try to use an embedded font
the bitmap background works just fine. But the fonts does not works.
When i use this same code in "foreground agent" the fonts shows perfectly.
Grid grid = new Grid();
// load your image
StreamResourceInfo info = Application.GetResourceStream(new Uri("tile.jpg", UriKind.Relative));
// create source bitmap for Image control (image is assumed to be alread 173x173)
WriteableBitmap wbmp2 = new WriteableBitmap(1, 1);
wbmp2.SetSource(info.Stream);
Image img = new Image();
img.Source = wbmp2;
// add Image to Grid
grid.Children.Add(img);
TextBlock text = new TextBlock()
{
FontFamily = new FontFamily("/MyTaskAgent;component/Fonts/Fonts.zip#Buxton Sketch"),
Foreground = new SolidColorBrush(Colors.Black) ,
TextWrapping = TextWrapping.Wrap,
};
text.Text = "Test";
// this is our final image containing custom text and image
WriteableBitmap wbmp = new WriteableBitmap(173, 173);
// now render everything - this image can be used as background for tile
wbmp.Render(grid, null);
wbmp.Invalidate();

我沸腾了降至任一
1. 在进行转换之前创建一个使用该字体的隐藏文本块，或者
2.创建一个FontSource。
我使用第一个，因为现在它更简单。
文本块是隐藏的，但它确保加载嵌入的字体。
在我的控制范围内，我添加了以下内容：
I had a similar problem, and found a solution, please have a look here or here
I boils down to either
1. creating a hidden textblock that use the font before doing the conversion, or
2. creating a FontSource.
I used the first because it was simpler for now.
The textblock is hidden, but it ensures that the embedded font is loaded.
Inside my control, I added the following:
我不确定该问题是否与发布的代码有关。我发现加载自定义字体可能需要相当长的时间，因此后台代理将在加载字体之前完成，因此不会渲染任何内容。
在调用
NotifyComplete()之前，您确定渲染已完成吗？I wouldn't be certain the issue is related to the posted code. I find it likely that loading a custom font, will take quite some time, and thus the Background Agent will finish before the font is loaded, and as such not rendering anything.
Are you certain the rendering completes, before you call
NotifyComplete()?
