Properties

Readonly complete

complete: boolean

Retrieves whether the object is fully loaded.

dataMode

dataMode: number

Applies to JPEG images drawn to PDF canvases only. Setting img.dataMode = Image.MODE_MIME or Image.MODE_MIME|Image.MODE_IMAGE enables image MIME data tracking. When MIME data is tracked, PDF canvases can embed JPEGs directly into the output, rather than re-encoding into PNG. This can drastically reduce filesize and speed up rendering.
