Importing images with transparency.

Hi!. I already submit a request about this but i would like to know the opinion of other people also.

I`m making an orthomosaic of a facade and I would like to know if there is any way to import images to the proyect wich I had previusly edited on photoshop to delete the parts of the pictures that wasn’t relevant for me. I start trying this method in order to optimize the processing time and i get great results but i still having some troubles.

Problem is that jpeg does not support transparency and it fills the empty parts with white color, so when I procces de densified point cloud and the 3d texture mesh i get this nasty white parts arround the facade wich i have to remove editing de point cloud in order to get the ortho as i want.
In addition, i want to export the 3d mesh , wich is not editable in pix4d, so then i have to remove again this white parts manually on the other software.

I try to import the images as .tiff saving with transparency but again the software fills the empty parts with white.

Sorry for my English but i m from Spain.

Thanks for your time

Hi David,

You should not preprocess your images in Photoshop. Pix4Dmapper gives you the tools to process part of your area. You have the following 2 options:

Draw a Processing Area: https://support.pix4d.com/hc/en-us/articles/202560589-How-to-Draw-a-Point-Cloud-Densification-Area-with-the-rayCloud

Annotate the images: https://support.pix4d.com/hc/en-us/articles/202560549-How-to-Annotate-Images-with-the-rayCloud

One of these options should work for you!
Best regards,
