Description

Hello
I am tgryiong to print a layout with 2 locked layers maps (different layers) and some HTML labels
I was trying to open a 2.18 project with the layout I wanted but composer crashed any time I tried to open it.
Then I eliminated that layout and started to create a new one, step by step.
All objects that I added were working fine.
I added the two map windows and some HTML labels and pictures, all fine
Then I saved, reopened my project and bang! Crash with composer.
No way to open my layout

Windows 10 pro (x64) on a powerful laptop
Qgis 3.4.6 downloaded via OSGEO4W

Here is the report

Thanks

Same behaviour with 3.6.1

#2 Updated by Giovanni Manghi 9 months ago

  • Affected QGIS version changed from 3.4.6 to 3.6.1
  • Priority changed from Normal to High

I was able to isolate the problem
I created item by item a new layout in a new project
As I added map frames to the layout there is no problem
As I inserted an HTML label pointing to a picture driven by atlas Qgis worked fine, maps were changing in their frames and picture is correctly changed in the HTML label frame.
Then I saved my project and reopen it, all ok. As I open the layout two map frames are initialized and the HTML label isn't, then qgis crashes

In the HTML label there is this code

<style>
  • {margin: 0px; padding: 0px; vertical-align: middle; horizontal-align: middle}
    </style>
    <img src="file:///E:/GIS/Monitoraggio/balneazione/fotoaree/[% "foto_area" ]"
    style="max-width: 100
    ; height: auto; display: block; margin: 0px 0px 0px 0px;" />

So a path with the column containing the picture to load for each atlas feature

I can confirm the problem is related to the html label
I opened my new project and saved as .qgs text file
Then I looked for the HTML label

The code I found is

<LayoutItem opacity="1" blendMode="0" position="282,3,mm" type="65641" size="135,83.859,mm" uuid="{befd256b-55d9-4d8b-a2bd-2e5bb9b8b3da}" excludeFromExports="0" positionOnPage="282,3,mm" outlineWidthM="1,mm" frame="true" htmlState="1" marginX="0" positionLock="false" id="" frameJoinStyle="miter" background="false" groupUuid="" referencePoint="0" marginY="0" zValue="3" visibility="1" labelText="&lt;style>&#xa;* {margin: 0px; padding: 0px; vertical-align: middle; horizontal-align: middle}&#xa;&lt;/style>&#xa;&lt;img src=&quot;file:///E:/GIS/Monitoraggio/balneazione/fotoaree/[% &quot;foto_area&quot; %]&quot;&#xa;style=&quot;max-width: 100%; height: auto; display: block; margin: 0px 0px 0px 0px;&quot; />" valign="32" templateUuid="{befd256b-55d9-4d8b-a2bd-2e5bb9b8b3da}" itemRotation="0" halign="8">
        <FrameColor alpha="255" green="158" red="245" blue="7"/>
        <BackgroundColor alpha="255" green="255" red="255" blue="255"/>
        <LayoutObject>
          <dataDefinedProperties>
            <Option type="Map">
              <Option name="name" type="QString" value=""/>
              <Option name="properties"/>
              <Option name="type" type="QString" value="collection"/>
            </Option>
          </dataDefinedProperties>
          <customproperties/>
        </LayoutObject>
        <LabelFont style="" description="Arial,10,-1,5,50,0,0,0,0,0"/>
        <FontColor green="0" red="0" blue="0"/>
      </LayoutItem>

changing the value visibility="1" to visibility="0" makes my layout open correctly.
The HTML label is hidden and I can toggle its visibility to on and pictures are shown. So it works.
If I set visible "on" for html label on my objects list then again next time I save/close qgis/ open project/load layout makes Qgis crash (the value visibility="1" is restored)

Pictures are .JPG 1134x780 res, 250/1100KB each
