How to render multiple lines with SDL _ TTF?
By putting the font glyphs into an atlas, and storing glyph metrics, you can easily render multiple lines, render each glyph in a different style or even font, do various effects, etc. By batching your glyph draws, you can be way more efficient than using SDL_TTF naively.
Are there any new functions in SDL2 TTF?
SDL2_TTF has new functions including TTF_RenderText_Blended_Wrapped, where you can specify a wraplength parameter, which specifies in pixels the maximal width ( the surface width also gets padded to this value ). It also supports newline characters, and will break the line at characters.
Do you need to copy lines into temporary SDL buffers?
There’s no need to copy whole lines into temporary SDL buffers which are copied to your real output. It’s harder, but worth it. Easy toy render APIs are just that: toys.
Can you use TrueType fonts in SDL applications?
This is a sample library which allows you to use TrueType fonts in your SDL applications. It comes with an example program “showfont” which displays an example string for a given TrueType font file. Portions of this software are copyright © 2014 The FreeType Project (www.freetype.org).
How do you use fonts in SDL2?
To actually use fonts, we first rendered text to a surface, then passed it to a texture, and finally to the GPU. We used SDL_QueryTexture () to obtain the dimensions of the texture, so that we could render the text in exactly as much space as it needed.
What kind of surface does SDL TTF use?
The returned SDL_Surface is a 32-bit ARGB surface with alpha transparency and anti-aliasing. Because this surface will blit slower than either solid or shaded rendered surfaces, you should use it for text that isn’t expected to change a lot. Fonts have properties and attributes that you can both set and retrieve. One is the font style.
What is the color of the box in SDL TTF?
The color of this box is the bg (background) color you pass to the function. If you’re unsure what anti-aliased means, it’s when an image (like text) is surrounded at its edges by pixels shaded roughly the same color as that part of the image.
