But why use this seemingly obscure format? It’s +easy to find TTFs but not easy to find FNTs (the canonical file +extension used for Angel Code fonts) and bitmap fonts don’t scale +well. The reason is efficiency. +</p> +<p>If all of the glyphs of a font are pre-rendered and packed into an +image file then it becomes possible to use a texture atlas +(see <a href="Textures.html#Textures">Textures</a>) and a sprite batch (see <a href="Sprites.html#Sprites">Sprites</a>) when +rendering, which is a more efficient way to render fonts than using, +say, <a href="https://www.libsdl.org/projects/SDL_ttf/">SDL_ttf</a> or other +solutions that involve using the FreeType library directly. +</p> +<p>Now what about scaling? In libraries that use TTF fonts, one must +choose the size that the glyphs will be rasterized at up front. To +use <code>n</code> sizes of the same font, one must load <code>n</code> variants +of that font. If the size of the text is dynamic, some kind of +texture scaling algorithm must be used and the text will inevitably +look blurry. At first glance, using bitmap fonts seem to have an even +worse issue. Instead of just loading the same font <code>n</code> times at +different sizes, one would need to generate <code>n</code> image files for +each font size needed. This is where the “signed distance field” +rendering technique comes in. Introduced by +<a href="http://www.valvesoftware.com/.../2007/SIGGRAPH2007_AlphaTestedMagnification.pdf">Valve</a> in 2007, signed distance field fonts can be efficiently stored +in a bitmap and be rendered at arbitrary scale factors with good +results. Chickadee can render both traditional bitmap fonts and +signed distance field fonts. <em>Signed distance field font +rendering is not yet available, so be patient.</em> +</p> +<p>While Chickadee does not yet offer a tool for converting TTF fonts +into FNT fonts, tools such as +<a href="https://github.com/libgdx/libgdx/wiki/Hiero">Hiero</a> may be used +in the meantime. +</p> +<p>The following procedures can be found in the <code>(chickadee render +font)</code> module. +</p> +<dl> +<dt><a name="index-load_002dfont"></a>Scheme Procedure: <strong>load-font</strong> <em><var>file</var></em></dt> +<dd><p>Load the Angel Code formatted XML document in <var>file</var> and return a +new font object. +</p></dd></dl> + +<dl> +<dt><a name="index-font_003f"></a>Scheme Procedure: <strong>font?</strong> <em><var>obj</var></em></dt> +<dd><p>Return <code>#t</code> if <var>obj</var> is a font object. +</p></dd></dl> + +<dl> +<dt><a name="index-font_002dface"></a>Scheme Procedure: <strong>font-face</strong> <em><var>font</var></em></dt> +<dd><p>Return the name of <var>font</var>. +</p></dd></dl> + +<dl> +<dt><a name="index-font_002dline_002dheight"></a>Scheme Procedure: <strong>font-line-height</strong> <em><var>font</var></em></dt> +<dd><p>Return the line height of <var>font</var>. +</p></dd></dl> + +<dl> +<dt><a name="index-font_002dline_002dheight-1"></a>Scheme Procedure: <strong>font-line-height</strong> <em><var>font</var></em></dt> +<dd><p>Return the line height of <var>font</var>. +</p></dd></dl> + +<dl> +<dt><a name="index-font_002dbold_003f"></a>Scheme Procedure: <strong>font-bold?</strong> <em><var>font</var></em></dt> +<dd><p>Return <code>#t</code> if <var>font</var> is a bold font. +</p></dd></dl> + +<dl> +<dt><a name="index-font_002ditalic_003f"></a>Scheme Procedure: <strong>font-italic?</strong> <em><var>font</var></em></dt> +<dd><p>Return <code>#t</code> if <var>font</var> is an italicized font. +</p></dd></dl> + +<dl> +<dt><a name="index-draw_002dtext"></a>Scheme Procedure: <strong>draw-text</strong> <em><var>font</var> <var>text</var> <var>position</var></em></dt> +<dd><p>[#:scale] [#:rotation] [#:blend-mode] +</p> +<p>Draw the string <var>text</var> with the first character starting at +<var>position</var> using <var>font</var>. +</p> +<div class="example"> +<pre class="example">(draw-text font "Hello, world!"

For 2D games, sprites are the +most essential graphical abstraction. They are used for drawing maps, +players, NPCs, items, particles, text, etc. In Chickadee, bitmaps are +stored in textures (see <a href="Textures.html#Textures">Textures</a>) and can be used to draw sprites +via the <code>draw-sprite</code> procedure. +</p> +<dl> +<dt><a name="index-draw_002dsprite"></a>Scheme Procedure: <strong>draw-sprite</strong> <em><var>texture</var> <var>region</var> [#:scale] [#:rotation] [#:blend-mode alpha] [#:texture-region] [#:shader]</em></dt> +</dl> + +<p>It’s not uncommon to need to draw hundreds or thousands of sprites +each frame. However, GPUs (graphics processing units) are tricky +beasts that prefer to be sent few, large chunks of data to render +rather than many, small chunks. Using <code>draw-sprite</code> on its own +will involve at least one GPU call <em>per sprite</em>, which will +quickly lead to poor performance. To deal with this, a technique +known as “sprite batching” can be used. Instead of drawing each +sprite immediately, the sprite batch will build up a large of buffer +of sprites to draw and defer rendering until the last possible moment. +Batching isn’t a panacea, though. Batching only works if the sprites +being drawn share as much in common as possible. Every time you draw +a sprite with a different texture or blend mode, the batch will be +sent off to the GPU. Therefore, batching is most useful if you +minimize such changes. A good strategy for reducing texture changes +is to stuff many bitmaps into a single image file and create a +“texture atlas” (see <a href="Textures.html#Textures">Textures</a>) to access the sub-images within. +</p> +<p>Taking advantage of sprite batching in Chickadee is easy, just wrap +the code that is calling <code>draw-sprite</code> a lot in the +<code>with-batched-sprites</code> form. +</p> +<dl> +<dt><a name="index-with_002dbatched_002dsprites"></a>Scheme Syntax: <strong>with-batched-sprites</strong> <em><var>body</var> …</em></dt> +<dd><p>Use batched rendering for all <code>draw-sprite</code> calls within +<var>body</var>. +</p></dd></dl> + +<p>With a basic sprite abstraction in place, it’s possible to build other +abstractions on top of it. One such example is the “nine patch”. A +nine patch is a sprite that can be rendered at various sizes without +becoming distorted. This is achieved by diving up the sprite into +nine regions: +</p> +<ul> +<li> the center, which can be scaled horizontally and vertically +</li><li> the four corners, which can never be scaled +</li><li> the left and right sides, which can be scaled vertically +</li><li> the top and bottom sides, which can be scaled horizontally +</li></ul> +<p>The one caveat is that the bitmap regions must be designed in such a +way so that they are not distorted when stretched along the affected +axes. For example, that means that the top and bottom sides could +have varying colored pixels vertically, but not horizontally. +</p> +<p>The most common application of this technique is for graphical user +interface widgets like buttons and dialog boxes.
