409d7bd3ce o Add a C-API (experimental right now, don't use yet) 
o Provide a shared library
 2016-05-05 08:29:51 -07:00

a559db250b o Allow to separate setting GPIO initialization from thread starting 
(but keep same defaults).

d7fd1fb561 o Added support for background colors on DrawText and DrawGlyph 
o Make the versions with the background the default functions, keep
  the old versions merely for compatibility.

7a0da0e136 o Add new transformers to provide logical Canvases that are transformed 
before writing to another physical Canvas.
   - RotateTransformer: rotates by multiple of 90 degrees
   - LargeSquare64x64Transformer: does the 64x64 conversion from
     earlier examples
   - LinkedTransformer allows to have a sequence of transformers
     applied.
o Provide a flag in demo-main to influence rotation.

273b294d5f o Move the concept of a pin-pulser to a class, so that we can create 
different implementations.

cde792d762 o Make slowdown of GPIO switchable. Make it default off, because the 
old Raspberry Pis should typically do fine (but their performance hurts
  a lot if this is switched on).
o Exposes the setting experimentally added in issue #16 in the Makefile.
o Update README describing what to do in these cases and how to switch
  it on.
 2015-03-04 23:08:43 -08:00

9c22cf8d2d o Ignore the black time for clocking and use the freedom to use 
shorter PWM base-time. Which then is used for 11 Bit PWM.
o implement CIE1931 luminance correction. Switch on by default.

b1f646057f o Move Canvas into separate file as preparation to be referenced 
in a little graphic primitives library later.
o Rename some methods while they are hopefully still not being used
  to much elsewhere: FillScreen() and ClearScreen() just becomes
  Fill() and Clear(). The affect a Canvas, not necessarily a Screen.
