17.2.8. The Picture and the North Arrow Items¶
The Picture item is a tool that helps decorate your map with pictures, logos… It can also be used to add north arrows, despite the dedicated North arrow tool.
22.214.171.124. The Picture Item¶
By default, the picture item is a blank frame that you can customize using its Item Properties panel. Other than the items common properties, this feature has the following functionalities (see figure_layout_image):
You first have to select the image you want to display. There are several ways to set the Image source:
In the Main properties group, use the … Browse button of image source to select a file on your computer. The browser will start in the SVG-libraries provided with QGIS. Besides
SVG, you can also select other image formats like
You can enter the source directly in the Image source text field. You can even provide a remote URL-address to a picture.
From the Search directories area you can also select an image from the loaded previews to set the image source. These images are by default provided by folders set in .
In the Search directories group, you can use the Add and Remove buttons in the group to customize the list of folders to fetch and preview images from.
With the Resize mode option, you can set how the image is displayed when the frame is resized:
Zoom: enlarges/reduces the image to the frame while maintaining aspect ratio of picture;
Stretch: stretches image to fit inside the frame, ignores aspect ratio;
Clip: use this mode for raster images only, it sets the size of the image to original image size without scaling and the frame is used to clip the image, so only the part of the image inside the frame is visible;
Zoom and resize frame: enlarges image to fit frame, then resizes frame to fit resultant image;
Resize frame to image size: sets size of frame to match original size of image without scaling.
Depending on the selected Resize mode, the Placement and Image rotation options are disabled or not. With Placement you can select the position of the image inside its frame.
QGIS default provided
.SVG files are customizable, meaning that you can
easily apply different Fill color, Stroke color
(including opacity) and Stroke width than the original, using their
corresponding feature in the SVG Parameters group. These properties
can as well be data-defined.
If you add a
.SVG file that does not enable these properties, you may
need to add the following tags to the file in order to add support e.g. for
You can read this blog post to see an example.
Images can be rotated with the Image rotation field. Activating the Sync with map checkbox synchronizes the rotation of the image with the rotation applied to a selected map item; this is a convenient feature for north arrows that you can align with either:
the Grid north: direction of a grid line which is parallel to the central meridian on the national/local grid;
or the True north: direction of a meridian of longitude which converges on the North Pole.
You can also apply a declination Offset to the picture rotation.
126.96.36.199. The North Arrow Item¶
Since north arrows are images, the North Arrow item has the same properties as the picture item. The main differences are:
A default north arrow is used when adding the item instead of a blank frame
The north arrow item is synced with a map item by default: the Sync with map property is filled with the map over which the north arrow item is drawn. If none, then it falls back to the reference map.
Many of the north arrows do not have an “N” added in the north arrow, this is done on purpose for languages that do not use an “N” for North, so they can use another letter.
