Edje Gradient Part

NOTE: this section is incomplete and sometimes just wrong, take with a considerable amount of salt.

The gradient type displays a color spectrum defined in the spectra block in many directions and shapes.

Gradient

gradient {
  spectrum: "spectrumName";
  type:     "gradientType";

  rel1 {
  }
  rel2 {
  }
}

The gradient block defines the necessary properties to display the spectrum.

spectrum

The name of the spectrum to display

type

Sets the gradient to one of the valid gradient types.

rel1

Not to be confused with the description block rel1, the gradient block rel1 sets the position of the first color of the spectrum.

rel2

As with rel1, the gradient block rel2 sets the position for the last color listed in the spectrum.

If either rel1 or rel2 is present in the gradient block of a linear gradient, these will override any angle/origin/size specified in the fill block ('spread' is still honored).

Depending on the gradient type, this block rel1 and rel2 might have different effects.

Fill

fill { 
  spread: 0-1; 
  angle:  0-1;
  origin {
  }
  size {
  }
}

The fill block defines the way the gradient fills the container, it works in the same way than image

Gradient types

Linear

This is the default gradient type, when the gradient block rel1 and rel2 are set, it traces a vector between them and display the colors in following that angle.

Radial

This gradient type draws the spectrum as a series of concentric rings centered by the origin property of the fill block.
