Adding An Image Logo At The Nadir Of A Spherical Panorama
In this page we will see how to add an image cap over the nadir of a Spherical Photography using the commercial software Pano2VR.
We will complete the process in three steps : first, we'll convert the panoramic image to a format that enables us to edit it without difficulty, then we'll edit it by adding the logo and finally we'll convert the edited image back into a panorama like the one we had at the beginning.
To get started, we will open our spherical image by dragging it to the main Pano2VR window. Immediately we'll see it open and marked as Input File. For this demonstration we'll use the 360 x 180 degree image that we created earlier with Autopano Pro which includes this program's watermarks :
In the right side Output File pane we'll choose Transformation as the new output format :
We will click on Add to see the transformation options :
Then a new window will open with the options to configure. We'll display the Types menu :
At this point there are different format types which would allow us to edit the nadir. For our example we'll choose the Horizontal Strip type :
With the format type already selected, we'll make sure to give the output image a size large enough not to loose image quality in the process. Note that this first transformation will be followed by two more, so it is always advisable to work on large images that can then be compressed before publishing. In this window we'll choose a file format for the transformed image, as well as a file name for it. The default location is in the same folder where the source file is, or we can place it elsewhere before clicking OK to get the process started :
A dialog window will ask us if we want to process the image immediately :
Once accepted, a progress indicator will show us the development of the process :
At the end of the transformation process, the output file pane at the main Pano2VR window will show us details of the created file :
The file has been created and we can find it at the location we had defined :
Having chosen a format transformation to Horizontal Strip now we have an image as the one below. The equirectangular image is now a strip of six squares, each one corresponding to a face of a cube which contains the projection of the scene. The first four faces are the sides of the image, while the fifth corresponds to the zenith or top end of the scene and the sixth is the nadir, or lower end. We'll continue working on this later square. Since we are using the trial version of Pano2VR the created image image contains watermarks created by the program, in addition to the existing Autopano Pro ones. These can be avoided acquiring a Pano2VR license :
For a few moments we'll leave Pano2VR aside and work with a common image editor. In this case we'll choose to use Gimp. To begin, we'll drag the image we've just created into the main Gimp's window to open the file. Once it's opened, we'll select the Zoom tool :
We'll use the zoom to enlarge the image and focus on the sixth face of the Horizontal Strip, corresponding to the nadir of the scene, in whose center we see the nodal rotator and/or tripod we want to hide :
In another Gimp window we'll open the image file which contains our logo, select the image and copy it to memory by using the Edit menu or the key combination Control + C. From the same Edit menu or by using the keys Control + V we'll paste the logo image over the Horizontal Strip. We'll use for this example a screen capture of 360 Facil homepage :
Using the Move tool from the tools menu and the mouse we'll post the logo on the nadir of our cubic image :
Activating the Select tool of the menu and clicking anywhere out of the image we'll anchor the new layer over the main image :
The image is already done. Now it only remains to create the file from the File menu by clicking on the Save As item :
If we opt for a format which allows for layer management such as PNG the program will ask us what to do with these. The default option is correct, so we can just click forward to combine the layers :
A new window will then open where we will define a file name and a location for it :
In the next and final Gimp window we find some advanced options, which we can skip altogether, and the ability to define the degree of compression for our image. A compression level of zero indicates an image without compression and consequently of a higher quality :
After clicking on Save the file will be created and we could find it there where we had choosen :
Our Horizontal Strip, now with the logo we have pasted over the nadir, looks as follows :
Now it only remains to give the edited image the aspect it had when we started, so now starting from the newly created image file, we'll drag it to the main Pano2VR window to use it as input file :
Repeating the steps we had previously followed, in the output file pane we'll choose Transformacion again :
Once again we'll click on Add to choose the format type that we want :
Now the new nadir of the scene is visible at the default image format :
This time, at the Type's drop down menu we'll choose Equirectangular :
As we had seen before, this is the window where to choose a name and location for the output file, as well as its format and image dimensions :
Once again, the software will ask us if the file creation should be immediately executed :
For a few moments as the remapping process goes we'll see the progress indicator :
Once the process is completed, at the output file pane in Pano2VR's main window we'll see the confirmation that the file has been created :
Since we had choosen the default location, the created file is at the same folder where we had saved all the intermediate files :
At the end of the process we have the created file with its logo capping the nadir. New Pano2VR watermarks have now been added to those from the first step of this page and those from AutoPano-Pro, so the image is rather overloaded with watermarks. All these can be avoided by using the registered versions of AutoPano-Pro y Pano2VR software. To see the created Spherical Panorama With Logo as an interactive Virtual Tour click on the image :
Starting on the next page we'll see step by step how to create a Spherical Panorama With Logo, similar to the one we've just created, but photographed by non aligned shots with a multiple row nodal rotator.
