QOpenGLPixelTransferOptions

PyQt5.QtGui.QOpenGLPixelTransferOptions

Description

The QOpenGLPixelTransferOptions class describes the pixel storage modes that affect the unpacking of pixels during texture upload.

Methods

__init__()

Constructs a new QOpenGLPixelTransferOptions instance with the default settings.

---

__init__(QOpenGLPixelTransferOptions)

TODO

---

alignment() → int

Returns the current alignment requirement for each pixel row.

---

imageHeight() → int

Returns the currently set image height.

See also

setImageHeight().

---

isLeastSignificantBitFirst() → bool

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

---

isSwapBytesEnabled() → bool

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

---

rowLength() → int

Returns the currently set row length.

See also

setRowLength().

---

setAlignment(int)

TODO

---

setImageHeight(int)

Sets the image height for 3D textures to imageHeight. Corresponds to GL_UNPACK_IMAGE_HEIGHT. The default value is 0.

See also

imageHeight().

---

setLeastSignificantByteFirst(bool)

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.

---

setRowLength(int)

Sets the number of pixels in a row to rowLength. Corresponds to GL_UNPACK_ROW_LENGTH. The default value is 0.

See also

rowLength().

---

setSkipImages(int)

Sets the number of images that are skipped to skipImages. Corresponds to GL_UNPACK_SKIP_IMAGES. Equivalent to incrementing the pointer passed to setData(). The default value is 0.

See also

skipImages().

---

setSkipPixels(int)

Sets the number of pixels that are skipped to skipPixels. Corresponds to GL_UNPACK_SKIP_PIXELS. Equivalent to incrementing the pointer passed to setData(). The default value is 0.

See also

skipPixels().

---

setSkipRows(int)

Sets the number of rows that are skipped to skipRows. Corresponds to GL_UNPACK_SKIP_ROWS. Equivalent to incrementing the pointer passed to setData(). The default value is 0.

See also

skipRows().

---

setSwapBytesEnabled(bool)

swapBytes specifies if the byte ordering for multibyte components is reversed. The default value is false. Corresponds to GL_UNPACK_SWAP_BYTES.

See also

isSwapBytesEnabled().

---

skipImages() → int

Returns the number of images that are skipped.

See also

setSkipImages().

---

skipPixels() → int

Returns the number of pixels that are skipped.

See also

setSkipPixels().

---

skipRows() → int

Returns the number of rows that are skipped.

See also

setSkipRows().
