Create a new image from the Raster rgba byte buffer defined by pBB. The dimensions of iWidth and iHeight are in logical units but the image doesn't scale if the resolution or zoom changes. Instead you must create a new image.

) [protected, virtual]

This method is just like drawChars() except it treats yoff as position of the font baseline. The default implementation simply subtracts the ascent of the current font from yoff and calls drawChars(), which should work on all platforms except for win32.

On win32 because of the trickery we use to achieve wysiwyg layout the acent of the font we work with is slightly smaller than that of the actual font the system uses to draw on the screen. As a result, the characters end up positioned slightly higher than they should and this has proved a problem in the math plugin (see screen shots in #9500)

WARNING! WARNING! WARNING! Only gr_UnixGraphics should call this! Because xap_UnixFontManager "owns" it's fonts, keeps it's own cache of them and will happily destroy them. If it does this, the cache of pointers here is no longer valid. It would be better to simply remove the font from this cache too but the key used in the xap_UnixFontManager class is different fromt the key used here. Until a better solution appears I'll leave this here. Other classes should use _destroyFonts to remove the cache.

void GR_Graphics::prepareToRenderChars ( GR_RenderInfo ri  )  [virtual]

prepareToRenderChars() does any preprocessing necessary immediately prior to the actual output on screen (which is done by renderChars()), and must be always called before renderChars().

What this function does is entirely dependend of the specific shaping engine (and in some cases might not do anthing at all). For example, this function might refresh any temporary buffers, etc.

The reason for dividing the actual drawing into two steps (prepare and render) is to limit the amount of processing in cases where the caller needs to make several calls to renderChars() with the same GR_RenderInfo. For example, fp_TextRun::_draw() draws the text in one, two or three segments depending whether there is a selection and where in the run it is. It will make one call to prepareToRenderChars() and then 1-3 calls to renderChars() chaning the background and text colour in between those calls.

void GR_Graphics::renderChars ( GR_RenderInfo ri  )  [virtual]

renderChars() outputs textual data represented by ri onto the device (screen, priter, etc.).

The output starts at ri.m_iOffset, is ri.m_iLength long and the drawing starts at ri.m_xoff, ri.m_yoff

UT_sint32 GR_Graphics::resetJustification ( GR_RenderInfo ri,
bool  bPermanent 
) [virtual]

resetJustification() makes the data represented by ri unjustified and returns value by which the total width changed as a result such that OriginalWidth + ReturnValue = NewWidth (i.e., the return value should normally be negative).

The parameter bPermanent indicates that the resetting is permanent and any buffers used to hold justification information can be remove, e.g., the paragraph alignment has changed from justified to left (in some circumstance the reset can be only temporary and we will be asked to subsequently recalculate the justification information; in such case it makes sense to keep the buffers in place)

bool GR_Graphics::shape ( GR_ShapingInfo si,
GR_RenderInfo *&  pri 
) [virtual]

shape() processes the information encapsulated by GR_ShapingInfo si and stores results in GR_*RenderInfo* pri.

If the contents of pri are NULL the function must create a new instance of GR_*RenderInfo of the appropriate type and store the pointer in pri; it also must store pointer to this graphics instance in pri->m_pGraphics.

If ri indicates that the text is justified, appropriate processing needs to be done

This function is tied closely together to a class derrived from GR_RenderInfo which may contain caches of various data that will speed subsequent calls to prepareToRenderChars() and renderChars()
