Image of existing plan can be imported into Floor Plan Creator. Imported image is displayed as a partially transparent layer over your plan and can be used as a template for drawing rooms and symbols.
Click here to see a short tutorial.
To import an image click "Image background" icon in the symbol toolbar, with "Structure" category selected. Application will ask you to pick an image from Gallery or Photos apps.
If you press "Image background" icon when background image is already present, then application will select background image and will let you delete it, adjust its scale and position.
When background image is selected, click toolbar icons to edit it: delete, scale, position.
Scale button is used to define size of imported image. Move start and end points of the dimension line to indicate known length on the image (for example dimension line, measured wall) and then click the button at the top of the screen and type known length. Click "Done" to complete.
Position button is used to move and rotate background image. On some devices rotated bitmaps are causing poor rendering performance, so it is advised to rotate the image using other software prior to importing, if you are affected by this issue.
To hide background image without deleting it from the project, click "Project" button in the toolbar and enable "Hide background images" checkbox.
Background images are not uploaded to the cloud.
Android 10 and newer: images are stored inside private application storage. When you uninstall the application, the OS will ask you whether you want to keep these files or delete them.
Android 9 and older: images are stored in FloorPlanCreator/.data directory, which is not deleted when application is uninstalled.
If you want to transfer background images to other devices you can either copy directory yourself (Android 9 and older) or click menu button on the list of plans view and select "Export backgrounds". That will create a file containing all your backgrounds that can be later imported back into Floor Plan Creator.
Background images are not deleted automatically when you delete a project referencing them. To remove unused images, click menu button and select "Delete unused backgrounds".
When background image file is missing (because project was downloaded from the cloud or because data directory was cleared), application will render crossed rectangle instead of the image in plan editor. Select the background and click "Import" in the toolbar to choose a new image from the Gallery.
Exported Floor Plan Creator projects files (.fpc) contain complete information: structure of the plan and background images used.
