 Example, converting a RGB color:
-R=255		→ 	R = 31 (because each pixel can only have 5 bits per color)
+R=255		→ 	R = 31 (because each pixel can only have 5 bits per color)<br />
-G=012		→	G = 1
+G=012		→	G = 1<br />

 All the data in a Ti.image is formatted in what we call bytes.
-A byte can look like this (without the quotes): "<tt>\255</tt>", "<tt>\129</tt>", "<tt>\045</tt>" or "<tt>.</tt>".
+A byte can look like this (without the quotes): "<tt>\255</tt>", "<tt>\129</tt>", "<tt>\045</tt>" or "<tt>.</tt>". The byte number ranges from \000 to \255
 If the byte number is reprecentable in ascii (and the nspire supports that char), it is allowed to just use the ascii version as byte, to lower the size of the image. For example, you can change "<tt>\046</tt>" to "<tt>.</tt>".
