Member Type Documentation
enum class QPdfDocumentRenderOptions::RenderFlag
flags QPdfDocumentRenderOptions::RenderFlags
This enum is used to describe how a page should be rendered.
| Constant | Value | Description |
|---|---|---|
QPdfDocumentRenderOptions::RenderFlag::None | 0x000 | The default value, representing no flags. |
QPdfDocumentRenderOptions::RenderFlag::Annotations | 0x001 | The page is rendered with annotations. |
QPdfDocumentRenderOptions::RenderFlag::OptimizedForLcd | 0x002 | The text of the page is rendered optimized for LCD display. |
QPdfDocumentRenderOptions::RenderFlag::Grayscale | 0x004 | The page is rendered grayscale. |
QPdfDocumentRenderOptions::RenderFlag::ForceHalftone | 0x008 | Always use halftones for rendering if the output image is stretched. |
QPdfDocumentRenderOptions::RenderFlag::TextAliased | 0x010 | Anti-aliasing is disabled for rendering text. |
QPdfDocumentRenderOptions::RenderFlag::ImageAliased | 0x020 | Anti-aliasing is disabled for rendering images. |
QPdfDocumentRenderOptions::RenderFlag::PathAliased | 0x040 | Anti-aliasing is disabled for rendering paths. |
The RenderFlags type is a typedef for QFlags<RenderFlag>. It stores an OR combination of RenderFlag values.
