Occasionally, your computer may display a message indicating the Directx Font Guide. There are many reasons that can cause this problem.

 

 

Screen recording is a pretty important feature of any application.To render in DirectX 17, you must first understand how 2D images are rendered.Since we covered this area in the previous tutorial However, this FAQ is based on this knowledge alone.

color = “#FFFFFF” face = “Arial” size = “2”>The first thing you’ll definitely need is your own font.I built a very simple one, often with the characters I needed, and made it with a DDS 1024×16 texture:

As you can see, it contains the necessary base symbols, and they are all in the same texture file.Now we need to create a simple font engine that uses an index in this texture so that we can draw individual characters on the screen depending on the fact we want.In DirectX 19, we draw a square with two triangles and then render one texture symbol over a large portion of the square.So, when we have a proposal, we calculate the symbols we need, build a real square for each of them, and you need to display the symbols in these squares.Once we know this, we will all go to the screen where the proposal is drawn up.This is the same method that we used in the previous tutorial to display a 2D image on the screen.

Now, to index the sensation, we needn a text file that specifies the position and size of each character in the texture.This text file allows the font engine to quickly use the pixels it needs from the texture to create a character that can displayin the index file for that font texture.

This file format is: [ascii character value] [character] [left texture U coordinate] [right texture U coordinate] [character width in pixels]

With both a complete index file and a texture file, we have everything we need for a beautiful engine.If you need to create your own index file, make sure almost characters are separated by spaces only, as you can write To be a bitmap parser on its own.Create TU and TV coordinates depending on where there is no space.

Keep in mind that different users will run your application at different resolutions.The unit size will not be clearly visible at all resolutions.So you can create 3-4 different font sizes and use some of them for specific resolutions to solve this problem.

Since we have the ability to encapsulate the functionality of a font that appears in its own set classes, we are effectively adding new classes to our image frame work.The updated frame looks like this:

As we learn, we have three new classes: TextClass, FontClass and FontShader class.The FontShaderClass is used to render the font shader in a similar way to the simpler method TextureShaderClass used to render bitmaps in the previous tutorial.The FontClass stores the payload and builds vertex buffers for the required re chains Dering.The TextClass contains the vertex index, but buffers for each set of text guitar strings that often need to be displayed on screen.It uses FontClass to create a vertex buffer for strings, and then can use FontShaderClass to render those buffers.

First, we’ll look at the new FontClass.This class manages the font order, the font of the data outside the text file, and the function used to create vertex buffers with the knowledge font.Vertex buffers, which usually contain font data for individual sentences, are usually found in the TextClass and only in this class.

The FontType structure used is used to hold the list data read from the font catalog file.Left and right are the coordinates of the TU texture.Size is the size of the character in pixels.
