Tips

• Contrast is the best tool to get more defined results
• Contrast flag is a percentage, while the others are multiplication factors
• Scale will usually need to be less than 0.3, as text is much larger than a pixel and most applications can only shrink so far
• the html output needs the tt tags, otherwise it is not monospaced
• the simpler the image, and the higher natural contrast between depth and color makes for a better result
• The sample shown above has good depth clarity, but complex color variation and textures making it a difficult (but doable) sample
• Since most text has a width of height ratio of 1:3, each pixel gets constructed using 3 pieces of text to retain ratio
