Member Function Documentation

drawRow()

void dw::core::style::StyleImage::StyleImgRenderer::drawRow ( int  row )

virtual

Called, when data from a row is available and has been copied into the image buffer.

The implementation will typically queue the respective area for drawing.

Implements dw::core::ImgRenderer.

References image.

fatal()

void dw::core::style::StyleImage::StyleImgRenderer::fatal ( )

virtual

Called, when there are problems with the retrieval of image data.

The implementation may use this to indicate an error.

Implements dw::core::ImgRenderer.

Definition at line 614 of file style.cc.

finish()

void dw::core::style::StyleImage::StyleImgRenderer::finish ( )

virtual

Called, when all image data has been retrieved.

The implementation may use this instead of "drawRow" for drawing, to limit the number of draws.

Implements dw::core::ImgRenderer.

Definition at line 609 of file style.cc.

setBuffer()

void dw::core::style::StyleImage::StyleImgRenderer::setBuffer ( core::Imgbuf *  buffer, bool  resize  )

virtual

Called, when an image buffer is attached.

This is typically the case when all meta data (size, depth) has been read.
