void ome::qtwidgets::glsl::v110::GLImageShader2D::setCoords ( const GLfloat *  offset = 0,
int  tupleSize = 2,
int  stride = 0 
)

Set vertex coordinates from array.

Parameters
offsetdata offset if using a buffer object otherwise the coordinate values.
tupleSizethe tuple size of the data.
stridethe stride of the data.

References attr_coords.

Referenced by ome::qtwidgets::gl::v20::Image2D::render(), and setCoords().

void ome::qtwidgets::glsl::v110::GLImageShader2D::setCoords ( QOpenGLBuffer &  coords,
const GLfloat *  offset = 0,
int  tupleSize = 2,
int  stride = 0 
)

Set vertex coordinates from buffer object.

Parameters
coordsthe coordinate values; null if using a buffer object.
offsetthe offset into the coords buffer.
tupleSizethe tuple size of the data.
stridethe stride of the data.

References setCoords().

void ome::qtwidgets::glsl::v110::GLImageShader2D::setCorrection ( const glm::vec3 &  corr)

Set correction multipliers to normalise pixel intensity.

Use to correct the pixel value limits to the storage size limits, for example when using data with 12 bits per sample with a 16-bit storage type it will require multiplying by 2^(16-12) = 2^4 = 16. To leave uncorrected, e.g. for float and complex types, and integer types where the bits per sample is the same as the storage size, set to 1.0.

Parameters
corrthe RGB channel correction multipliers.
