◆ generateDrawable()

sk_sp< SkDrawable > SkScalerContextProxy::generateDrawable ( const SkGlyph & )

overrideprotectedvirtual

Returns the drawable for the glyph (if any).

The generated drawable will be lifetime scoped to the lifetime of this scaler context. This means the drawable may refer to the scaler context and associated font data.

The drawable does not need to be flattenable (e.g. implement getFactory and getTypeName). Any necessary serialization will be done with makePictureSnapshot.

Reimplemented from SkScalerContext.

Definition at line 71 of file SkTypeface_remote.cpp.

                                                                       {
    TRACE_EVENT1("skia", "generateDrawable", "rec", TRACE_STR_COPY(this->getRec().dump().c_str()));

    }
 
    fDiscardableManager->notifyCacheMiss(
            SkStrikeClient::CacheMissType::kGlyphDrawable, fRec.fTextSize);
    return nullptr;
}

◆ generateFontMetrics()

void SkScalerContextProxy::generateFontMetrics ( SkFontMetrics * )

overrideprotectedvirtual

Retrieves font metrics.

Implements SkScalerContext.

                                                                     {

        SkDebugf("GlyphCacheMiss generateFontMetrics: %s\n", this->getRec().dump().c_str());
    }
 
    // Font metrics aren't really used for render, so just zero out the data and return.
    fDiscardableManager->notifyCacheMiss(
            SkStrikeClient::CacheMissType::kFontMetrics, fRec.fTextSize);
    sk_bzero(metrics, sizeof(*metrics));
}

◆ generateImage()

void SkScalerContextProxy::generateImage	(	const SkGlyph &	glyph,
		void *	imageBuffer
	)

overrideprotectedvirtual

Generates the contents of glyph.fImage. When called, glyph.fImage will be pointing to a pre-allocated, uninitialized region of memory of size glyph.imageSize(). This method may not change glyph.fMaskFormat.

Because glyph.imageSize() will determine the size of fImage, generateMetrics will be called before generateImage.

Implements SkScalerContext.

    }
 
    // There is no desperation search here, because if there was an image to be found it was
    // copied over with the metrics search.
    fDiscardableManager->notifyCacheMiss(
            SkStrikeClient::CacheMissType::kGlyphImage, fRec.fTextSize);

    return {glyph.maskFormat()};
}

◆ generatePath()

bool SkScalerContextProxy::generatePath	(	const SkGlyph &	,
		SkPath *
	)

overrideprotectedvirtual

Sets the passed path to the glyph outline. If this cannot be done the path is set to empty; Does not apply subpixel positioning to the path.

Returns: false if this glyph does not have any path.
