Device class
Device class
This class encapsulates rendering of document to abstract device. Rendering of the document is performed page by page.
The Device type exposes the following members:
Properties
| Property | Description |
|---|---|
| creator | Returns or specifies creator of resulting device output. |
| size | Returns or specifies a size of the page. |
| is_direct_rgb | Indicates whether device uses direct RGB mode, that is RGB. |
| background | Returns or specifies current background of the page. |
| opacity | Returns or specifies current opacity. |
| stroke | Returns or specifies current stroke. |
| paint | Returns or specifies current paint. |
| opacity_mask | Returns or specifies current opacity mask. |
| char_tm | Returns or specifies current characters transform. |
| text_rendering_mode | Returns or specifies current text rendering mode. |
| text_stroke_width | Returns or specifies current text stroke width. |
| version | Current device version. |
