CGraphicsOutput

class ikomia.dataprocess.pydataprocess.CGraphicsOutput

Define task output containing graphics items. Consult GraphicsItem to see the list of possible graphics types. Instance can be added as output of a CWorkflowTask or derived. This kind of output is used to manage graphics items generated in a task. Ikomia software displays it as an overlay layer on top of images or videos. Graphics items can then be forwarded as input of workflow’s following tasks. Derived from CWorkflowTaskIO.
