Options for rendering text.
| Enumerator | |
|---|---|
| AlwaysOutlines | Always render text using path objects (AKA outlines/curves). This setting guarantees the best quality rendering, even when using a raster paint surface (where sub-pixel path based text rendering is superior to sub-pixel text-based rendering). The downside is that text is converted to paths only, so users cannot open created vector outputs for post-processing in other applications and retain text editability. This setting also guarantees complete compatibility with the full range of formatting options available through QgsTextRenderer and QgsTextFormat, some of which may not be possible to reproduce when using a vector-based paint surface and TextFormatAlwaysText mode. A final benefit to this setting is that vector exports created using text as outlines do not require all users to have the original fonts installed in order to display the text in its original style. |
| AlwaysText | Always render text as text objects. While this mode preserves text objects as text for post-processing in external vector editing applications, it can result in rendering artifacts or poor quality rendering, depending on the text format settings. Even with raster based paint devices, TextFormatAlwaysText can result in inferior rendering quality to TextFormatAlwaysOutlines. When rendering using TextFormatAlwaysText to a vector based device (e.g. PDF or SVG), care must be taken to ensure that the required fonts are available to users when opening the created files, or default fallback fonts will be used to display the output instead. (Although PDF exports MAY automatically embed some fonts when possible, depending on the user's platform). |
| PreferText | Render text as text objects, unless doing so results in rendering artifacts or poor quality rendering (depending on text format settings). When rendering using TextFormatAlwaysText to a vector based device (e.g. PDF or SVG), care must be taken to ensure that the required fonts are available to users when opening the created files, or default fallback fonts will be used to display the output instead. (Although PDF exports MAY automatically embed some fonts when possible, depending on the user's platform).
