Max Lyons has just recently posted an update to PTAssembler, his popular panoramic and high resolution image mosaic creation software. This program give tremendous control over the output of stitched and stacked images and is the software I use for my larger or more complicated panoramas.
Version 5.0 Features/Changes:
PTAssembler 5.0 is major upgrade from PTAssembler 4.0, largely due to the fact that it now includes its own stitching and optimizing program: PTAStitcher. PTAssembler can now operate completely independently of Panorama Tools, although it can still be configured to work with Panorama Tools if desired.
PTAStitcher performs the same image optimizing duties as PTOptimizer, and the same image stitching duties as PTStitcher and/or PTMender. However, PTAStitcher adds a number of enhancements such as faster operation, multi-threading, better ability to handle very large images, new output formats, more image projections and other features.
PTOptimizer, PTStitcher and PTMender are still supported, but PTAStitcher is the default choice for both optimizing and stitching. Support for PTOptimizer, PTStitcher and/or PTMender may be removed in future versions of PTAssembler.
Feature: Added support for Photoshop large file (PSB) format (PTAStitcher only).
Feature: Added support for new standard output projections (PTAStitcher only):
- Miller Cylindrical (http://mathworld.wolfram.com/MillerCylindricalProjection.html)
- Lambert Azimuthal Equal Area (http://mathworld.wolfram.com/LambertAzimuthalEqual-AreaProjection.html)
- Orthographic (http://mathworld.wolfram.com/OrthographicProjection.html)
- Cassini (http://mathworld.wolfram.com/CassiniProjection.html)
- Cylindrical Equal Area (http://mathworld.wolfram.com/CylindricalEqual-AreaProjection.html)
- Lambert Cylindrical (http://mathworld.wolfram.com/LambertCylindricalEqual-AreaProjection.html)
- Behrmann Cylindrical (http://mathworld.wolfram.com/BehrmannCylindricalEqual-AreaProjection.html
- Cylindrical Equidistant (http://mathworld.wolfram.com/CylindricalEquidistantProjection.html)
- Miller Equidistant 1,2,3 (http://mathworld.wolfram.com/MillerEquidistantProjection.html)
Feature: Added support for several newly created, non-standard output projections (PTAStitcher only):
- Squeezed Rectilinear. Rectilinear in central region, and “squeezed” towards edges to minimize stretching typically visible in rectilinear projections. Both horizontal lines and vertical lines are rendered as straight lines throughout entire image.
- Compressed Rectilinear. Horizontal and vertical lines are straight, user can configure the amount of compression.
- Rectilindrical. Configurable projection that can produce “intermediate” projections that are a combination of rectilinear, cylindrical and equirectangular projections.
- Trans Merc Rectilinear. A combination of transverse mercator and rectilinear projections. Both horizontal lines and vertical lines are rendered as straight lines throughout entire image.
- Recti-Perspective. Vertical and radial lines are straight. Useful for “perspective” type images.
- Recti-Cylindrical. Rectilinear in central region, transitioning to cylindrical at edges.
- Hybrid. User selects one projection for each quadrant of output image, creating a composite projection.
- User Defined. User specifies formulas that are used to perform all projection math by PTAStitcher/PTAssembler. User defined projections are slower than built-in projections, but are useful for experimenting/prototyping new projections. Little error checking…The user is responsible for ensuring that the formulas are valid.
