enum class Qgis::MapLayerRendererFlag : int

strong

Flags which control how map layer renderers behave.

Since

QGIS 3.34

Enumerator
RenderPartialOutputs	The renderer benefits from rendering temporary in-progress preview renders. These are temporary results which will be used for the layer during rendering in-progress compositions, which will differ from the final layer render. They can be used for showing overlays or other information to users which help inform them about what is actually occurring during a slow layer render, but where these overlays and additional content is not wanted in the final layer renders. Another use case is rendering unsorted results as soon as they are available, before doing a final sorted render of the entire layer contents.
RenderPartialOutputOverPreviousCachedImage	When rendering temporary in-progress preview renders, these preview renders can be drawn over any previously cached layer render we have for the same region. This can allow eg a low-resolution zoomed in version of the last map render to be used as a base painting surface to overdraw with incremental preview render outputs. If not set, an empty image will be used as the starting point for the render preview image.
AffectsLabeling	The layer rendering will interact with the map labeling. Since QGIS 3.40

RenderPreviewJob	Render is a 'canvas preview' render, and shortcuts should be taken to ensure fast rendering.
RenderBlocking	Render and load remote sources in the same thread to ensure rendering remote sources (svg and images). WARNING: this flag must NEVER be used from GUI based applications (like the main QGIS application) or crashes will result. Only for use in external scripts or QGIS server.
LosslessImageRendering	Render images losslessly whenever possible, instead of the default lossy jpeg rendering used for some destination devices (e.g. PDF). This flag only works with builds based on Qt 5.13 or later.
Render3DMap	Render is for a 3D map.
HighQualityImageTransforms	Enable high quality image transformations, which results in better appearance of scaled or rotated raster components of a map. Since QGIS 3.24
SkipSymbolRendering	Disable symbol rendering while still drawing labels if enabled. Since QGIS 3.24
ForceRasterMasks	Force symbol masking to be applied using a raster method. This is considerably faster when compared to the vector method, but results in a inferior quality output. Since QGIS 3.26.1
RecordProfile	Enable run-time profiling while rendering. Since QGIS 3.34
AlwaysUseGlobalMasks	When applying clipping paths for selective masking, always use global ("entire map") paths, instead of calculating local clipping paths per rendered feature.

Antialiasing	Use antialiasing while drawing.
RenderPartialOutput	Whether to make extra effort to update map image with partially rendered layers (better for interactive map canvas). Added in QGIS 3.0.
RenderPreviewJob	Render is a 'canvas preview' render, and shortcuts should be taken to ensure fast rendering.
RenderBlocking	Render and load remote sources in the same thread to ensure rendering remote sources (svg and images). WARNING: this flag must NEVER be used from GUI based applications (like the main QGIS application) or crashes will result. Only for use in external scripts or QGIS server.
RenderSymbolPreview	The render is for a symbol preview only and map based properties may not be available, so care should be taken to handle map unit based sizes in an appropriate way.
LosslessImageRendering	Render images losslessly whenever possible, instead of the default lossy jpeg rendering used for some destination devices (e.g. PDF). This flag only works with builds based on Qt 5.13 or later.
ApplyScalingWorkaroundForTextRendering	Whether a scaling workaround designed to stablise the rendering of small font sizes (or for painters scaled out by a large amount) when rendering text. Generally this is recommended, but it may incur some performance cost.

Usually feature geometry clipping occurs using the extent() in the layer's CRS prior to geometry transformation, but in some cases when extent() could not be accurately calculated it is necessary to clip geometries to mapExtent() AFTER transforming them using coordinateTransform().
RenderingSubSymbol	Set whenever a sub-symbol of a parent symbol is currently being rendered. Can be used during symbol and symbol layer rendering to determine whether the symbol being rendered is a subsymbol. Since QGIS 3.24

SkipSymbolRendering	Disable symbol rendering while still drawing labels if enabled. Since QGIS 3.24
RecordProfile	Enable run-time profiling while rendering. Since QGIS 3.34
AlwaysUseGlobalMasks	When applying clipping paths for selective masking, always use global ("entire map") paths, instead of calculating local clipping paths per rendered feature. This results in considerably more complex vector exports in all current Qt versions. This flag only applies to vector map exports. Since QGIS 3.38
DisableSymbolClippingToExtent	Force symbol clipping to map extent to be disabled in all situations. This will result in slower rendering, and should only be used in situations where the feature clipping is always undesirable. Since QGIS 3.40

TextRenderFormat

enum class Qgis::TextRenderFormat : int

strong

Options for rendering text.

Since

QGIS 3.22

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.
