Member Function Documentation

◆ alignment()

int QOpenGLPixelTransferOptions::alignment ( ) const

Returns: the current alignment requirement for each pixel row.

Definition at line 96 of file qopenglpixeltransferoptions.cpp.

◆ imageHeight()

int QOpenGLPixelTransferOptions::imageHeight ( ) const

Returns: the currently set image height.

Definition at line 168 of file qopenglpixeltransferoptions.cpp.

◆ isLeastSignificantBitFirst()

bool QOpenGLPixelTransferOptions::isLeastSignificantBitFirst ( ) const

Returns: true if bits within a byte are ordered from least to most significant.

Definition at line 205 of file qopenglpixeltransferoptions.cpp.

◆ isSwapBytesEnabled()

bool QOpenGLPixelTransferOptions::isSwapBytesEnabled ( ) const

Returns: true if the byte ordering for multibyte components is reversed.

Definition at line 223 of file qopenglpixeltransferoptions.cpp.

◆ operator=()

QOpenGLPixelTransferOptions & QOpenGLPixelTransferOptions::operator= ( const QOpenGLPixelTransferOptions & rhs )

Definition at line 70 of file qopenglpixeltransferoptions.cpp.

◆ rowLength()

int QOpenGLPixelTransferOptions::rowLength ( ) const

Returns: the currently set row length.

Definition at line 186 of file qopenglpixeltransferoptions.cpp.

◆ setAlignment()

void QOpenGLPixelTransferOptions::setAlignment ( int alignment )

Sets the alignment requirements for each pixel row.

Corresponds to GL_UNPACK_ALIGNMENT. The default value is 4, as specified by OpenGL.

Definition at line 88 of file qopenglpixeltransferoptions.cpp.

◆ setImageHeight()

void QOpenGLPixelTransferOptions::setImageHeight ( int imageHeight )

Sets the image height for 3D textures to imageHeight.

Corresponds to GL_UNPACK_IMAGE_HEIGHT. The default value is 0.

Definition at line 160 of file qopenglpixeltransferoptions.cpp.

◆ setLeastSignificantByteFirst()

void QOpenGLPixelTransferOptions::setLeastSignificantByteFirst ( bool lsbFirst )

lsbFirst specifies if bits within a byte are ordered from least to most significat.

The default value is false, meaning that the first bit in each byte is the most significant one. This is significant for bitmap data only. Corresponds to GL_UNPACK_LSB_FIRST.
