What PTAssembler is

PTAssembler is a Windows program for stitching single-row panoramas and multi-row, high-resolution mosaics. It offers both automated creation and manual control, with tools such as a graphical preview editor, a beginner wizard, automatic positioning optimization, image-stack alignment, batch processing, and drag-and-drop. It can stitch pictures taken from different vantage points, supports standard and exotic projections, and can correct exposure, white balance, and vignetting. Exposure- and focus-blended panoramas are supported; TuFuse is included, with optional Enfuse or CombineZM. Enblend, Smartblend, and Multiblend plugins can help blend images when lighting changes or subjects move. Output options include JPEG, TIFF, PSD, PSB, and layered PSD, PSB, or multiple TIFF files. The source-image screen can display JPEG, BMP, and TIFF files. PTAssembler requires Visual Basic 6 runtime files. Its maker lists version 6.3.0, updated July 2017, and provides documentation, a tutorial, and a discussion forum. A 30-day trial is available; registration unlocks the full version, while unregistered use has restricted features after the trial. No price is listed.
