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.

enum class Qgis::TextRenderFormat : int

strong

Flags which control how map layer renderers behave.

Since

QGIS 3.34 Options for rendering text.

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).

SCALE_PRECISION

const double Qgis::SCALE_PRECISION = 0.9999999999

static

Fudge factor used to compare two scales.

The code is often going from scale to scale denominator. So it looses precision and, when a limit is inclusive, can lead to errors. To avoid that, use this factor instead of using <= or >=.

UI_SCALE_FACTOR

const double Qgis::UI_SCALE_FACTOR = 1

static
