Make a Java GUI which would display updates.

Given that a Canvas can have things added and removed, a Book also should have this privilege. It will allow pages to be removed dynamically without rewiring the entire render tree.

Font's when rendered do not obey DWIDTH and as such some fonts display incorrectly.

It might be useful to convert to greyscale for clarity. Take the brightness of each pixel and just create an RGB of a shade of white.

From https://stackoverflow.com/questions/14330/rgb-to-monochrome-conversion:
mono = (0.2125 * color.r) + (0.7154 * color.g) + (0.0721 * color.b);

Like brightness it will need to buffer it's original pixels.

When rendering a font of different height characters they are all rendered justified against the top of the text area.

Create a Displayable which creates a bigger area then it's parent, the layout can then manually scroll the display by shifting it's view over the whole area.

• Horizontal Only? You could get a vertical by mounting a horizontal in a rotate.
• Speeds?
• Repeat options:
  • Continuous loop
  • Bounce from side to side.
  • Just resets to beginning.
• Allow smart sizing, where size adapts to the most right hand none black pixel.

If a page updates the same pixels as the pagination indicators they will be wiped out.

Display a static image in a Displayable.

• To keep library light, accept custom format? Just rows/columns of PixelColours?

The PixelPusher output has no tests, write two tests for partial frame update and key frame updates.

Like PixelPusher there are no tests surrounding the Seraph output protocol.

Allow stacking of displayables on top of each other. Rendering top down, if a layers pixel is (0,0,0) then the next layer below checked, all the way down.

This allows animations and other effects to play on top of others.

Virtual layout is a bigger area then the parent can display with a view port which can be moved around. This may be helpful for the scrolling feature.

Consider adding wrapping, i.e. if you display past the right we show the left columns.

Convert text to pixels, obvious enough.

• Use BDF fonts? Simple and a library to chose from.
• What happens if Displayable isn't big enough?

Add a layout component which scales the size of the child.

• Start with a simple 2x/3x first.
• Do we want resampling or smoothing?
