Generated Font Spritesheet isn't right.

description

This is the output of:
tb = new TextBlockRenderer(sprite, "Arial",
    SlimDX.DirectWrite.FontWeight.Bold, 
    SlimDX.DirectWrite.FontStyle.Normal,
    SlimDX.DirectWrite.FontStretch.Normal, 12); 
The generated texture is:

(I made the background black btw)

Can anyone explain why the texture is cut-off ?

Thanks for posting the issue.
Unfortunately, I cannot reproduce the problem. I just released a new version of the library which fixes some bugs in the font alignment system. Please check if the problem still occurs with the new version.
The new version also contains a sample app (in the source repository) which you can use to test some basic functionality.

I couldn't open the project (not the right visual studio, I'm using VS2010 ) but after creating a new project, adding the source code, + Slimdx.dll and SpriteTextRenderer.dll I get the same result.

The only changed I made:
 Device.CreateWithSwapChain(DriverType.Hardware, DeviceCreationFlags.Debug, desc, out device, out swapChain);
To:
 Device.CreateWithSwapChain(DriverType.Hardware, DeviceCreationFlags.None, desc, out device, out swapChain);
Because for some reason I can't create it with the Debug Flag (I'm re-installing the DX SDK right now, just to be sure) but I have the same result.

Because your sample isn't working, I'm just guessing its my configuration. My video card is a NVIDIA GeForce GTX 560M.

The blending works perfectly, even thought I handled that before. Sprites also render perfectly, but the rendering of the CharTable doesn't seem to be right (on my hardware).

Could it be that my video card doesn't support non-rectangular textures (only width = height), because the texture does generate a texture of 128x256.. But I believed that was a "old" limitation.

TL[i].Metrics.LayoutWidth and TL[i].Math.Ceiling(TL[i].Metrics.LayoutHeight is always 0.. that doesn't seem right.

Nico201 wrote Sep 24, 2013 at 10:05 PM

It's ok that LayoutWidth and LayoutHeight are both 0. That's because there is no layout rectangle provided. The necessary values can be calculated from the other values.
What OS are you running? I just found that the char table renders empty on a Windows 8.1 machine. And since the Windows 8.1 SDK is still in Preview state, I don't want to install it and thus cannot switch the device to Debug. But I doubt that this has something to do with the Debug flag. The DirectWrite, Direct2D and Direct3D10 devices are created without the debug flag.
I'll investigate this further.

I'm running Windows 7 64 Bit (I do compile both 32 bit and 64 bit, no differents, btw: also your source code & the precompiled one )

I also do not believe it has anything to do with the Debug flag, I'm just saying I couldn't run it without changing it, (In some rare cases, it does make a differents)

It could have something to do with you scaled display:
User DPI Setting: 120 DPI (125 percent)
Could you try to change that for a moment?

MarijnStevens wrote Sep 25, 2013 at 8:56 AM

That was the problem, the resulting texture (on 96dpi):

But, while using 96dpi, the result was:

So, I've still having problem with rendering it seems.

I've hacked the source, so it can handle any DPI (I've 120 for a reason ;) )
Don't know if there is a better way for it, but it works.
public TextBlockRenderer(...) {
            ....

            float scaleX = (96.0f / D2DFactory.DesktopDpi.Width);
            float scaleY = (96.0f / D2DFactory.DesktopDpi.Height);
            
            rtp = new RenderTargetProperties()
            {
                HorizontalDpi = D2DFactory.DesktopDpi.Width * scaleX,
                VerticalDpi = D2DFactory.DesktopDpi.Height * scaleY,
                Type = RenderTargetType.Hardware,
                PixelFormat = new PixelFormat(Format.R8G8B8A8_UNorm, AlphaMode.Premultiplied),
                MinimumFeatureLevel = FeatureLevel.Direct3D10
            };

Darn I sound negative, but I'm not, I'm happy I can use it =D

Thanks. I'll run a few test with scaled displays and the next release should be out there in a few days.

The new release is out and should resolve the problem. Here is a screenshot with 125% scaled display, Windows 8.
Thanks again for your participation.
