Segment drawing options

Draw segment order numbers

Draw the order numbers of all segments within their way.
Advance preference: draw.segment.order_number

Advance preference: mappaint.node.virtual-size

Options that affect drawing performance

These options are only available in Expert mode.

Smooth map graphics (antialiasing)

Apply antialiasing to the map view resulting in a smoother appearance.
Advance preference: mappaint.use-antialiasing

Smooth map graphics in wireframe mode (antialiasing)

Apply antialiasing to the map view in wireframe mode resulting in a smoother appearance.
Advance preference: mappaint.wireframe.use-antialiasing

Highlight target ways and nodes

Highlight target nodes and ways while drawing or selecting.
Other objects glow when they are in the catch radius of the mouse pointer.
Advance preference: draw.target-highlight

Draw only outlines of areas

This option suppresses the filling of areas, overriding anything specified in the active styles.
Advance preference: draw.data.area_outline_only

Hide labels while dragging the map

This option hides the textual labels of OSM objects while dragging the map.
Advance preference: mappaint.hide.labels.while.dragging

Other options

Draw boundaries of downloaded data

Draw the boundaries of data loaded from the server.
When downloading an area you get and see all the data within the rectangular bounding box you chose. This includes some ways extending outside that box. It therefore becomes difficult to distinguish which areas contain full or partial data. If you check the "Draw boundaries of downloaded data" box, yellow hatching is drawn over all the areas into which data has not been fully downloaded. You should avoid adding or editing data in areas of yellow hatching as it may duplicate already existing data or conflict with data you don't see.
Advance preference: draw.data.downloaded_area

This option can be changed with Draw boundaries of downloaded data on the View menu, too.

Draw inactive layers in other color

Draw the inactive data layers in a different color.
Map objects not on the Active data layer are drawn in grey color.
Advance preference: draw.data.inactive_color

Display discardable keys

Display keys which have been deemed uninteresting to the point that they can be silently removed. (Expert mode only)
They will be listed in light grey color in the Tags/Memberships panel. These outdated keys will be stripped off from modified objects on upload.
Advance preference: display.discardable-keys

Use auto filters

Display buttons to automatically filter numeric values of a predefined tag.
Auto filters can be enabled here and the tag to be used for the autofilter can be chosen.
Advance preference: auto.filter.enabled

Rule

Rule defining which tag will provide automatic filters, below a certain zoom level.
Advance preference: auto.filter.rule
