In QGIS 3.4 I have imported my customised icon (which was obtained through the .jpeg image conversion) for point layers using an SVG file.

This works well except for the fact that the original colour was replaced by black.

Under the "Symbology" menu I cannot change the colour of the "SVG marker" (see picture below).

If I try to change it in the level above under "Marker" this does not change the colour of the icon. Any ideas or suggestions?

Example

Here is the code of my SVG (opened in Browser):

<?xml version="1.0" standalone="no"?>

  • which software did you use to create the svg?

  • I downloaded a jpeg image and converted it online to svg. This worked fine for another icon (although to be fair, that one was black to start with). @Taras where can I find the code?

You can simply do it directly in QGIS via Layer Properties > Draw Effects > Effect Properties.

Open your SVG Layer Properties and click Draw Effects and then open the Star symbol Customize effects Customize_effects.

SVG_Layer_Properties

Then use Colorise as an Effect type

Effect_properties

  • I am wondering which brightness I have to chose to get the exat color which I chose in the color picker for areas which were black in the SVG.

You need to edit the SVG file and replace the

fill="#000000" stroke="none"

by something like

fill="param(fill) #FFF" stroke="param(outline) #000" stroke-width="param(outline-width) 1"

the "param(xxx)" part allow you to set the xxx parameter from the qgis interface, the #XXX part is the default color.

For a more detailled explanation see this answer How to create svg symbols that have modifiable fill color, stroke color and stroke width?

  • This is the best answer, IMO, as it also enables changing styling of image objects in the map composer. I've been doing this for SVG images for a while now when I wanted to be able to style logos directly in the composer and this method doesn't require to dig into a couple dialogs to change the color.

Using notepad++ (or any other decent text editor) simply change in this part

<g transform="translate(0.000000,390.000000) scale(0.100000,-0.100000)" fill="#000000" stroke="none">

the code for "fill" to any desired color. E.g. fill="rgb(0,255,0)" for a green symbol.

  • great, I will download notepad++. However, as I have no clue with this, may I also ask how the code would be for a dark pink / purple colour?

  • Feel free to google for a website which gives you RGB-codes for any color you like. E.g. rapidtables.com/web/color/RGB_Color.html

Using Inkscape, simply saving the file in the format Plain SVG, rather than Inkscape SVG will work without any need to edit the file afterwards. Plain SVG uses parameters like QGIS instead of a style setting.

However, this appears to only work if there are just two objects in the icon, any more and not all the colours, etc will change within QGIS settings. Perhaps someone can provide a workaround for this.

For example:

This is the code of an icon/file saved in Inkscape SVG

    <?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!-- Created with Inkscape (http://www.inkscape.org/) -->

<svg
   width="100"
   height="100"
   viewBox="0 0 26.458333 26.458333"
   version="1.1"
   id="svg1"
   inkscape:version="1.3.2 (1:1.3.2+202311252150+091e20ef0f)"
   sodipodi:docname="landuse_symbol.svg"
   xmlns:inkscape="http://www.inkscape.org/namespaces/inkscape"
   xmlns:sodipodi="http://sodipodi.sourceforge.net/DTD/sodipodi-0.dtd"
   xmlns="http://www.w3.org/2000/svg"
   xmlns:svg="http://www.w3.org/2000/svg">
  <sodipodi:namedview
     id="namedview1"
     pagecolor="#ffffff"
     bordercolor="#000000"
     borderopacity="0.25"
     inkscape:showpageshadow="2"
     inkscape:pageopacity="0.0"
     inkscape:pagecheckerboard="0"
     inkscape:deskcolor="#d1d1d1"
     inkscape:document-units="mm"
     inkscape:zoom="5.45"
     inkscape:cx="50"
     inkscape:cy="35.321101"
     inkscape:window-width="1440"
     inkscape:window-height="742"
     inkscape:window-x="0"
     inkscape:window-y="0"
     inkscape:window-maximized="1"
     inkscape:current-layer="layer1" />
  <defs
     id="defs1" />
  <g
     inkscape:label="Layer 1"
     inkscape:groupmode="layer"
     id="layer1">
    <circle

fill="param(fill) #00ffff" stroke="param(outline) #000000" stroke-width="param(outline-width) 0.395835"
       id="path1"
       cx="13.229167"
       cy="13.229167"
       r="13.031249" />
    <path
       style="fill:#00ffff;stroke:#000000;stroke-width:0.390181"
       d="M 13.109259,26.215461 V 0.6672652 L 25.792503,13.558712 H 13.076272"
       id="path2" />
  </g>
</svg>

And this is the same icon/file saved in 'Plain SVG'

    <?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!-- Created with Inkscape (http://www.inkscape.org/) -->

<svg
   width="100"
   height="100"
   viewBox="0 0 26.458333 26.458333"
   version="1.1"
   id="svg1"
   xmlns="http://www.w3.org/2000/svg"
   xmlns:svg="http://www.w3.org/2000/svg">
  <defs
     id="defs1" />
  <g
     id="layer1">
    <circle
       fill="param(fill) #00ffff"
       stroke="param(outline) #000000"
       stroke-width="param(outline-width) 0.395835"
       id="path1"
       cx="13.229167"
       cy="13.229167"
       r="13.031249" />
    <path
       style="fill:#00ffff;stroke:#000000;stroke-width:0.390181"
       d="M 13.109259,26.215461 V 0.6672652 L 25.792503,13.558712 H 13.076272"
       id="path2" />
  </g>
