Expand description

Update of a persistent resource in WebRender.

ResourceUpdate changes keep theirs effect across display list changes.

§

SetBlobImageVisibleArea(BlobImageKey, DeviceIntRect)

See AddBlobImage::visible_area.

§

AddFont(AddFont)

See AddFont.

§

DeleteFont(FontKey)

Deletes an already existing font resource.

It is invalid to continue referring to the font key in any display list in the transaction that contains the DeleteImage message and subsequent transactions.

§

AddFontInstance(AddFontInstance)
