Re: [PanoToolsNG] Re: Speed up panotools - No masks
- It was some time since I updated the code that creates the masks for
layered Photoshop files. From what I remember many of the other imaging
applications could not open the files if they did not have both the clip
mask and image mask.
Masks should only be necessary if feathering is used. They do compress
very well. I had to use some hack to determine at the time of creating
the image mask whether or not feathering was selected or not.
With the new PTMender we will have many more options. The file size
should be smaller.
It will need to be investigated again. It is likely that there is a
better way to implement the masking. At the time I was trying to not to
add the image mask if they were not needed. But unfortunately they were
needed by some imaging applications.
And if you are creating PSB files they are coming from PTGui not
PanoTools. PSB will not be an option included in PanoTools. Adobe's
license agreement does not allow it be used in open source software.
I have put a request into Adobe for an updated SDK several weeks ago. I
have not heard back yet. I have not tried CS3 yet. I will investigate
any improvements to the plug-ins first.

who knows the internals of PSB format ;-)
You should ask Joost directly - could well be he doesn't read here at
Resources, not only for panorama creation:
- Just want to repeat my question.
Maybe it got lost somehow (no answer yet).
Any advice appreciate.
