Function Documentation

bool ome::qtwidgets::textureConversionRequired ( ::ome::xml::model::enums::PixelType pixeltype )

Check if type conversion is required.

Conversion will be required if the GL type does not match the corresponding PixelType language type.

Parameters

pixeltype the PixelType to query.

Returns: true if conversion is required, false otherwise.

GLenum ome::qtwidgets::textureExternalFormat ( ::ome::xml::model::enums::PixelType pixeltype )

Get the default external (GL) pixel format of a PixelType.

Parameters

pixeltype the PixelType to query.

Returns: the GL external format.

GLint ome::qtwidgets::textureExternalType ( ::ome::xml::model::enums::PixelType pixeltype )

Get the default external (GL) type of a PixelType.

Parameters

pixeltype the PixelType to query.

Returns: the GL external type.

GLenum ome::qtwidgets::textureInternalFormat ( ::ome::xml::model::enums::PixelType pixeltype )

Get the default internal (GL) pixel format of a PixelType.

Parameters

pixeltype the PixelType to query.

Returns: the GL internal format.

GLenum ome::qtwidgets::textureInternalFormatFallback ( GLenum format )

Get a fallback internal (GL) pixel format.

The fallback format will have the same channel count as the specified format, lower quality (smaller size) or different type (int rather than float).

Parameters

format the format which is not suitable.

Returns: a downgraded format compared with the specified format.

GLint ome::qtwidgets::textureMagnificationFilter ( ::ome::xml::model::enums::PixelType pixeltype )

Get the default magnification filter.

Parameters

pixeltype the PixelType to query.

Returns: the default magnification filter.

GLint ome::qtwidgets::textureMinificationFilter ( ::ome::xml::model::enums::PixelType pixeltype )

Get the default minification filter.

Parameters

pixeltype the PixelType to query.

Returns: the default minification filter.

bool ome::qtwidgets::textureNormalizationRequired ( ::ome::xml::model::enums::PixelType pixeltype )

Check if normalization is required.

Normalization will be required if the GL type is not automatically normalized. For example, this is usually automatic for integer types when using a floating point internal format, but will be required when using a floating point data, e.g. in a fragment shader, or before setting the texture.

Parameters

pixeltype the PixelType to query.

Returns: true if normalization is required, false otherwise.

ome::xml::model::enums::PixelType ome::qtwidgets::texturePixelTypeFallback ( ::ome::xml::model::enums::PixelType pixeltype )

Get a fallback pixel type.

The fallback format will have a lower quality (smaller size) or different type (int rather than float). If no fallback is available, the same type will be returned.

Parameters

pixeltype the PixelType to query.

Returns: a downgraded PixelType.
