+# px_ascii
+
+Generate 8x8 pixel points of printable ASCII characters (codes 32dec to 126dec). You can use these points to build pixel-style models. 
+
+**Since:** 2.1
+
+## Parameters
+
+- `char` : A printable ASCII character.
+- `center`: . If `true`, object is centered in X- and Y-axis. Otherwise, the object is placed in the positive quadrant. Defaults to `false`.
+- `invert`: Inverts points of the character. Default to `false`. 
+
+## Examples
+
+    include <pixel/px_from.scad>;
+    include <pixel/px_ascii.scad>;
+
+    for(i = [0:94]) {
+        translate([8 * (i % 10), -8 * floor(i / 10), 0]) 
+            for(p = px_ascii(chr(i + 32))) {
+                translate(p) 
+                    linear_extrude(1, scale = 0.8) 
+                        square(1);
+            }
+    }
