I need to do some rudimentary text rendering to a pixel buffer, and I think that having a table indexed by char with the representation of the letters as a binary array would be more than enough Anybody knows about a free header as such?

I could go on with the rest of the alphabet, but then I wouldn't need to ask Update : I tried this approach and the characters come out fairly distorted. Possibly Nimbus is a poor font choice. Even though Nimbus-Mono-Regular is a monospace font, sometimes the character widths are off by a pixel.

The convert option "-resize 7x13! Again, this might be a problem specifically with the Nimbus font. I know you can save images as a c header file in gimp. Maybe you can find a tool which does the job on the command line. So you could automate the creation.

ImageMagick can at least load ttf fonts. Loading a tga file is pretty simple. I wouldn't expect a crowdsourced font to look very nice. Learn more. C header file with bitmapped fonts Ask Question.

Brilliant, where did you get this from? I notice that lower scanlines come first and left pixels are in more significant bits.

Silicon Graphics released that bit map here: courses. Could you share the Gimp instructions for producing that code? That's exactly what I want to do to render fonts for a simple embedded system.TrueType port of a good-old Korean bitmap font, with enhancements.

Willy is a monospaced font created a long ago by my demoscene friend Willy, it's perfect for displaying ascii-art.

May 23, Apr 5, May 12, The simplest and fastest method, a texture is pre-built for each piece of text that needs to be displayed. This method produces high quality, scalable text, but this is also the slowest approach due to the overhead of generating and rendering the glyph polygons. These extensions do a great job of text rendering.

However, these libraries are not universally available on all systems and I have a bad habit of trying to be portable and platform independent. Bitmap fonts are fast, flexible and platform independent. However, there are some limitations: Quality suffers when scaling up the texture and the number of possible characters in a font bitmap is limited. Extended or Unicode character sets with accents or non-latin symbols are not well supported.

[C++ OpenGL] Bitmap Font Rendering Sample

A bitmapped font is simply an atlas texture containing a collection of glyphs and symbols. Note: the purple lines are a visual aid, they do not appear on the actual texture. The grid layout means that the calculation required to select any given character is quick and simple.

The area containing the selected characters can then be mapped onto a series of polygons to create dynamic strings of text. Adding width information to the glyphs allows the textured quads to be overlapped to create better looking text with variable character widths.

So I wrote my own. Many people have made useful suggestions that have been implemented in CBFG, and the tool has been used on the following projects:.

Polymer theme by pdevtytweaked by Codehead.Feb 7, at am UTC. Hello Could someone offer their opinion or statements of fact : on which method is the best way to render a bitmap font in OpenGL? Most tutorials I have found do something like: load up a TTF and convert it to a pixel image.

This is not what I want, as I already have my own texture atlas'd bitmap font on a single x image. Furthermore, I don't need or want any texture filtering, scaling, rotating, etc -- I just want to plaster the pixels of the letter directly onto the screen at a pixel-perfect ratio. I'm not fully comfortable yet with OpenGL but I've come across several different possibilities as methods: - 1 The TTF-to-pixel way, which I don't want - 2 Render each letter to a quad?

This seems iffy to me as I do not require any transforms from projection space, screen space, filtering, etc. I just want to paste the pixels directly to the screen. Render-to-texture tutorials I've found often use the function glViewportbut this is only for rendering the entire window to a texture, I think. This function has pixel-perfect parameters but I get the impression that calling this function once per letter would be Right now I only have basic experience thus far with a basic vertex shader and a fragment shader.

What's the best way to implement this? Last edited on Feb 7, at am UTC. Feb 7, at pm UTC. First create a texture the same size as the screen you may want to want to check the NPOT extension is available, which thankfully it pretty much always is nowadays and a normal buffer that is, a regular array in main memory in the same format as the texture. To update the contents of the screen you write to the buffer at the appropriate locations, and then when it's time to render the frame you upload it to the GPU.

Now, this texture-buffer pair only describes the entire screen. You can choose to store your font glyphs prior to rendering however you like Now to render the texture on the screen you can use glBlitFramebuffer. Thank you for the reply! To update the contents of the screen you write to the buffer at the appropriate locations Yes, sorry, that is the specific part I intended to ask about.

Or "stamping" the individual letters onto the buffer if you will. Last edited on Feb 7, at pm UTC. Well, in the specific phrase you quoted I'm talking about a plain-ol' buffer. That is, an array in memory. I assume you know how to write bytes to memory. Feb 8, at am UTC. If so Sorry if I'm misunderstanding here.

I suppose I could store each letter individually as plain pixel data on CPU which I believe you suggested on the first postbut I was hoping there was a dedicated OpenGL technique for copying an exact rect of one OpenGL texture, and pasting it directly onto a rect of another OpenGL texture. Maybe SDL spoiled me by having methods that allowed you to specify a unique rect for both source and dest.

Well, in that case you can use IINM glBlitNamedFramebuffer to transfer from the font texture to the screen texture, and then again from the screen texture to the framebuffer. You can of course transfer directly from the font to the framebuffer, but if you use an intermediate texture you only need to copy from the font when the text on the screen changes. If you transfer directly from the font to the framebuffer you need to redraw every frame because the framebuffer is either in a cleared or indeterminate state.

Unless by "overlay" you're referring to some specific concept I know that word used to refer to some kind of video rendering that was used in the pastI addressed that, didn't I? I proposed using an intermediate texture in between the font texture and the framebuffer to only have to redraw the text when it changes.RAGAZZO DEL CORSA back from 20 week spell and placed at last trial at this track, could upset.
