uv2xy, xy2uv

These two functions are used for conversion between UV coordinates and XY coordinates by performing simple multiplication and division.

uv2xy(vec2)

Description:

• Calculate xy values from given uv values.

Parameter:

• vec2 : uv position value.

Returns:

• vec2 : xy position value.

Note: If the layer dimensions are 1280 x 720, uv2xy(vec2(0.1,0.5)); returns vec2(128.0,360.0);

xy2uv(vec2)

Description:

• Calculate uv values from given xy values.

Parameter:

• vec2 : xy position value.

Returns:

• vec2 : uv position value.

Note: If the layer dimensions are 1920 x 1080, xy2uv(vec2(192,108)); returns vec2(0.1,0.1);
