12.6 New graphics ports features

Unless otherwise stated, for details see the Graphics Ports chapters in the CAPI User Guide and Reference Manual. This section is not relevant to LispWorks for Mobile Runtime.

12.6.1 Newly documented initargs for external-image

The initargs :data, :transparent-color-index and :type are now documented for the class graphics-ports:external-image, allowing external images to be created from a vector of bytes.

12.6.2 gp:make-image-from-port should not be used with capi:output-pane

We recommend not using gp:make-image-from-port with a capi:output-pane, because it might be impossible to get the correct pixel information. On macOS, it will signal an error. Only use gp:make-image-from-port with a gp:pixmap-port.
