Large panoramas beyond 300.000 pixels?

by marz71 » Mon Jul 28, 2008 3:05 pm

Photoshop .psb format has a limitation of 300.000 x 300.000 pixels.

Is there a way to create larger panoramas than the 300.000 pixel limitation?
The final image would be exported to HDView.

Is it possible to use GigaTiler to create several panoramas and then merge them to one huge HDView content? How to align/crop the pictures?

Regards,
Marek Rzewuski

In the future BigTiff format will support larger files, http://www.awaresystems.be/imaging/tiff/bigtiff.html for now your best bet is the photoshop raw (not to be confused with camera raw).

The psb format could handle more than 300,000 pixels. There is no real reason for this limitation. So what could be possible is to render to PSB and reuse the gigatiler to export to hdview. The 300,000 limit should not be a problem. The only issue is that this psb could not be opened in photoshop. I wonder if we have coded a warning dialog box about the limit or if it is a stopping dialog box in the render dialog ... I have to check.

About bigtiff. Tiff is a problem : specifications of the bigtiff are around since years, but as noone is really responsible of the tiff specification, everybody is doing their own stuff and tiff format is already a big mess with many contradictory spec.

Photoshop RAW : doesn't it have the same limit as photoshop 300,000 ? Because 300,000 is an internal photoshop limit not a format limit.

I confirms it's a photoshop limitation.

Does the photoshop .psd (that's a D) format have the same limitation? That's what I use for larger panos. I have had problems getting APP to write .psds though. I believe I am correct in saying that it is known that the psd-writer in the Linux 1.4.2 version is bugged so I have to do the render in Windows. I have also had problems with Windows version 1.4.2 though. On my machine it seems that I need to have the original images on the same disk as APP. Weird I know, but a repeatable problem. I have no experience of APP on a Mac though, sorry.

HTH

The Psd format has a 30,000 x 30,000 limitation. You cannot go over this value with Autopano. In fact, it switches automatically to psb.
PSB can only be read by photoshop CS and over.

There are two facts here : the psd/psb writer on linux has an awkward bug when reaching the 2 gigapixels limits ( 95% it just works, but sometimes it doesn't work. We didn't find a repeatable case yet even with package from customers). The windows version has not at all this bug, 32 bits or 64 bits. It works great. But for example if you use smartblend, this one just put a huge amount of stress over the system that could crash.

I have found another program which can read PSB files: Toby Thain's psdparse. You can get it from this URL:

http://www.telegraphics.com.au/sw/

Scan down to the bottom of the page for psdparse. Versions since October 13, 2008, will compile on GNU/Linux and will read PSB (and PSD) files written by AutoPano Pro. If you specify --writepng it will convert the PSB/PSD file to PNG format. There is also a version available for Microsoft Windows.

Here is the detailed description of the program:

About psdparse
--------------

This utility parses and prints a description of various structures
inside an Adobe Photoshop(TM) PSD or PSB format file.
It can optionally extract raster layers and spot/alpha channels to PNG files.

A reasonable amount of integrity checking is performed. Corrupt images may
still cause the program to give up, but it is usually much more robust
than Photoshop when dealing with damaged files: It is unlikely to crash,
and it recovers a more complete image.

Tested with PSDs created by PS 3.0, 5.5, 7.0, CS and CS2,
in Bitmap, Indexed, Grey Scale, CMYK and RGB Colour modes
and 8/16 bit depths, with up to 53 alpha channels.

32-bit channels can be extracted, but only to 'raw' format files.

This software uses zlib which is (C) Jean-loup Gailly and Mark Adler.


How to use
----------

To use the utility, run it giving the path name of the PSD file
you want to inspect:
./psdparse filename

* For a guide to options, './psdparse --help'
* For detailed text output, use the --verbose option.
* To minimise text output, use the --quiet option.
* To extract PNG files of raster layers, use the --writepng option.
* To name layer files with numbers, instead of actual layer names,
use --numbered option.
* To write an XML file describing the document and its layers,
use option --xml.
* To write the XML to standard output (e.g. for redirection or piping
to another tool), use option --xmlout.
* To write a text file describing layers, sizes and positions (list.txt),
use option --list. This file is put in the same directory as PNGs.
* To process 'image resources' (metadata), use the option --resources.
Information on image resources is printed to console, and XML if enabled.
* To process 'additional data' (layer types supported by Photoshop 4.0
and later, as well as objects such as patterns and annotations),
use the option --extra.
* Normally, RGB images (and grey scale+alpha images) are written as composite
PNG with channels combined in one file. To write individual PNG files
for each channel, regardless of mode, use the --split option.
* To specify a destination directory for PNGs, use the --pngdir option
followed by the directory path. This directory will be created if it
does not exist. (By default, a directory is created next to the input
PSD file, with '_png' appended.)
* To automatically create subdirectories when layer names include slashes,
use the --makedirs option (for example, layers named "scene/house/roof",
"scene/sky", "scene/trees/pine" will result in directories "scene",
and in that directory, two directories "house" and "trees"; the files
"sky.png", "roof.png" and "pine.png" will be in each respectively.)
Without this option, slashes in filenames will be replaced by underscores (_).
(N.B. In MPW, the directory separator is : instead of /.)
Subdirectories may be arbitrarily deep.

Yes. See the screenshot before, it's photoshop RAW.
