Text widget, Part 2

I finnaly add some effects to the text widget.
The reflection and the "skew".

All these effects are based upon the cairo.Matrix transform


Let start with a simple text displaying hour with a 3-colours and linear gradient:

   text_settings={
  {
  text=conky_parse("${time %H:%M:%S}"),
  font_name="Rasheeq",
  x=50,  
  y=50,
  font_size=50,
  colour={{0,0xFF0000,1},{0.5,0xFFFF00,1},{1,0x00FF00,1}},
  orientation="nn",
  },  
   }

The output :



Now, I add some reflection :

  {
  text=conky_parse("${time %H:%M:%S}"),
  font_name="Rasheeq",
  x=50,  
  y=50,
  font_size=50,
  colour={{0,0xFF0000,1},{0.5,0xFFFF00,1},{1,0x00FF00,1}},
  orientation="nn",
  reflection_alpha=1,
  },

The reflection start with an opacity of 1 (reflection_alpha=1) and ends with a opacity of 0.


But the reflection can start with an opacity less than 1 (reflection_alpha=0.5 here) :

  {
  text=conky_parse("${time %H:%M:%S}"),
  font_name="Rasheeq",
  x=50,  
  y=50,
  font_size=50,
  colour={{0,0xFF0000,1},{0.5,0xFFFF00,1},{1,0x00FF00,1}},
  orientation="nn",
  reflection_alpha=0.5,
  },   

With the abvoe parameters, reflection ends at the end of the text size, but it can end before with reflection_length=0.5, it means 50% of the full height of the text

  {
  text=conky_parse("${time %H:%M:%S}"),
  font_name="Rasheeq",
  x=50,  
  y=50,
  font_size=50,
  colour={{0,0xFF0000,1},{0.5,0xFFFF00,1},{1,0x00FF00,1}},
  orientation="nn",
  reflection_alpha=0.5,
  reflection_length=0.5,
  },   

The reflection length can be scaled, a scale of 1 (default value) means the same size of the text, a scale bigger than one means that the reflection is higher of the text:

  {
  text=conky_parse("${time %H:%M:%S}"),
  font_name="Rasheeq",
  x=50,  
  y=50,
  font_size=50,
  colour={{0,0xFF0000,1},{0.5,0xFFFF00,1},{1,0x00FF00,1}},
  orientation="nn",
  reflection_alpha=0.5,
  reflection_scale=2,
  },  

The skew parameter around x axis (I'm not sure of the units for that !):

  {
  text=conky_parse("${time %H:%M:%S}"),
  font_name="Rasheeq",
  x=50,  
  y=50,
  font_size=50,
  colour={{0,0xFF0000,1},{0.5,0xFFFF00,1},{1,0x00FF00,1}},
  orientation="nn",
  skew_x=20,
  },  

The skew parameter around y axis

  {
  text=conky_parse("${time %H:%M:%S}"),
  font_name="Rasheeq",
  x=50,  
  y=50,
  font_size=50,
  colour={{0,0xFF0000,1},{0.5,0xFFFF00,1},{1,0x00FF00,1}},
  orientation="nn",
  skew_y=20,
  },  

We can combine both

  {
  text=conky_parse("${time %H:%M:%S}"),
  font_name="Rasheeq",
  x=50,  
  y=50,
  font_size=50,
  colour={{0,0xFF0000,1},{0.5,0xFFFF00,1},{1,0x00FF00,1}},
  orientation="nn",
  skew_y=-20,
  skew_x=-50,
  },  

Unfortunately, we can't have a real perspective with cairo .


Finally, we can combine reflection and skew:

  {
  text=conky_parse("${time %H:%M:%S}"),
  font_name="Rasheeq",
  x=50,  
  y=900,
  font_size=50,
  colour={{0,0xFF0000,1},{0.5,0xFFFF00,1},{1,0x00FF00,1}},
  orientation="nn",
  skew_y=-20,
  skew_x=-10,
  reflection_alpha=0.5,
  },
