THPDFProgressiveRenderStatus Type

Tracks the state machine of a progressive page render as driven by ContinueProgressive

Declaration

THPDFProgressiveRenderStatus= (prsReady, prsPaused, prsCompleted,
    prsCancelled);

HPDFPageRenderer

Value	Meaning
`prsReady`	The render is reset or still has page objects waiting to be dealt with
`prsPaused`	The render is suspended in between time slices
`prsCompleted`	All page objects were processed and the result can be collected
`prsCancelled`	The render was cancelled and will process no objects further

Read the ProgressiveStatus property of THPDFPageRenderer between ContinueProgressive calls to decide whether to carry on
prsCompleted and prsCancelled are terminal; further work calls for the progressive render to be reset first
A cancellation token or a failing progressive image decode pushes the render into prsCancelled
