Supported image formats

TissUUmaps can read whole slide images in any format recognized by the OpenSlide library:

  • Aperio (.svs, .tif)

  • Hamamatsu (.ndpi, .vms, .vmu)

  • Leica (.scn)

  • MIRAX (.mrxs)

  • Philips (.tiff)

  • Sakura (.svslide)

  • Trestle (.tif)

  • Ventana (.bif, .tif)

  • Generic tiled TIFF (.tif)

TissUUmaps will automatically convert any other format into a pyramidal tiff (in a temporary .tissuumaps folder created in the original image folder) using vips.

If your image fails to open, try converting it to tif format using an external tool.

Load images

You can load the images when you select the Image layer tab as you can see in the figure below: Image layers

Then click the button Add image layer and select the desired image from your computer. Subsequently, the image is listed in the Image layer tab. You can load several images into TissUUmaps. Image more layers

You can also drag and drop the image from file explorer into TissUUmaps. drag and drop

Load images using TissUUmaps server

If you are running TissUUmaps in server mode and not through the GUI, you must specify an image folder in the command line:

python -m tissuumaps "/home/username/Documents/myImages/" -p 5005

You can then access your images from your web browser by accessing the url http://localhost:5005, and using the File > Open menu.

Apply filters

You can apply several filters to the images. The ones we can be adjusted by default are saturation, brightness, and contrast. Additionally, when opening the Filter settings menu, there are various other filters, such as exposure, noise, erosion, etc. When you check their box, they are automatically added to the filter panel above. The filter’s sliders can be adjusted so that the filter is applied at the desired intensity. Another option in filter settings is merging mode (bottom part), where you can merge the channels as a composite.

Apply transformations

From the image list in the right menu, you can apply several transformations to each image individually: translation, scale, rotation and flip. Markers and regions linked to the image will be transformed accordingly.
