Limitations

CGUIEdit

GUIEdit does only work for horizontally left-alignment text (class CGUIEdit).

CGUIScrollingText

GUIScrollingText Text alignments will have no effect in the direction of scrolling. I.e., vertical alignment will be ignored for vertically scrolling text.(Class CGUIScrollingText)

CGfxWrapBLU

Transparencies are not supported for GUIBitmapPlane_BLU. (Class CGUIBitmapPlane_BLU) Roation is not supported

GfxWrapDAVEHD

GfxWrapDAVEHD does not support rotation for blits. (Class CGfxWrapDAVEHD)

CGfxWrapeGML

Transparencies are not supported for GUIBitmapPlane_eGML. (Class CGUIBitmapPlane_eGML)

CFntWrapGlyphLib

As the CFntWrapGlyphLib uses a pre-compiled ROMFS to store the glyph bitmaps, it is not possible to change the number of used fonts via SetNOFFonts()

CSndWrapALSA

SndWrapALSA can only playback one sound at a time. Simultaneous playback of several sounds is not possible. (Class CSndWrapALSA)

CGfxWrapDirectFb

Rotated blits are unsupported. Parameters are ignored.

Ellipse primitives are unsupported.

Filtering on scaled blits is device dependent. It is enabled on platform that support it.

it is recommended to match pixel formats of input images and video outputs. When using bpp < 24 bit the behaviour of conversions are undefined.

CGUIBitmapPlaneDirectFb

Rotation is not supported.

3D functions are not supported.

Alpha Values can only be set globally (Top left alpha is used).

CGUIInputDirectFb

Apostrophes are not supported.

ALT GR+keys (i.e. @ on german latin-1) are not supported.

GfxWrap_stm32f429

Since BLU does not support RotBlits, it is not possible to rotate image at runtime; BlitImgExtImpl() must be only called with vAngle set to 0.

For additional details see description of base class CGfxWrap.

GfxWrap_stm32f746

Since BLU does not support RotBlits, it is not possible to rotate image at runtime; BlitImgExtImpl() must be only called with vAngle set to 0.
