Description

Shader that applies a contrast, brightness and saturation filter to a texture.

The coloradjustment shader exposes the following shader variables:

uniform UBO
{
    float contrast;     // Contrast adjustment [-1.0, 1.0]
    float brightness;   // Brightness adjustment [-x, x]
    float saturation;   // Saturation adjustment [0.0, x]
};
 
uniform sampler2D colorTexture;

Member Function Documentation

init()

virtual bool init ( utility::ErrorState &  errorState )

overridevirtual

Cross compiles the font GLSL shader code to SPIR-V, creates the shader module and parses all the uniforms and samplers.

Parameters

errorState

contains the error if initialization fails.

Returns

if initialization succeeded.

Reimplemented from Object.
