## Member Function Documentation

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

Set vertex coordinates from array.

Parameters

  offset | data offset if using a buffer object otherwise the coordinate values.
  tupleSize | the tuple size of the data.
  stride | the stride of the data.

References attr_coords.

Here is the caller graph for this function:

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

  coords | the coordinate values; null if using a buffer object.
  offset | the offset into the coords buffer.
  tupleSize | the tuple size of the data.
  stride | the 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

  corr | the RGB channel correction multipliers.
