The image_types
class defines all of
the standard image output types that you can enable through the
IMAGE_FSTYPES
variable.
You can use this class as a reference on how to add support for custom
image output types.
By default, this class is enabled through the
IMAGE_CLASSES
variable in
image.bbclass
.
If you define your own image types using a custom BitBake class and
then use IMAGE_CLASSES
to enable it, the custom
class must either inherit image_types
or
image_types
must also appear in
IMAGE_CLASSES
.
