Panorama Input Requirements
PanoView Editor is engineered exclusively for full 360° x 180° spherical panoramic imagery. Panoramas must satisfy equirectangular projection geometry and supported document color modes before perspective view extractions can execute.
Equirectangular projection with a 2:1 width-to-height ratio (360° horizontal by 180° vertical coverage).
RGB Color at 8 Bits/Channel or native 16 Bits/Channel.
Any active Photoshop document meeting 2:1 equirectangular geometry and supported RGB color depth.

Geometry & Aspect Ratio
Equirectangular projection maps the entire 360° sphere onto a flat plane, resulting in an exact 2:1 aspect ratio:
Aspect Ratio Validation & Tolerance
PanoView Editor validates incoming document proportions upon opening. Canvas dimensions must adhere to the 2:1 ratio within a supported ±2% tolerance. Common validated dimensions include:
If an image falls outside the ±2% tolerance (such as a 3:1 flat panorama crop or a standard 3:2 photograph), the panel indicates that the document is non-equirectangular.
Color Mode & Bit Depth
PanoView Editor supports native professional color pipelines without down-converting precision:
Fully supported. Fast rendering and low memory footprint for web delivery and standard photography.
Fully supported natively. No silent 8-bit downscaling or intermediate precision reduction during reprojection.
Unsupported for production reprojection. Convert to 16 Bits/Channel in Photoshop prior to editing.
Photoshop Compatibility
PanoView Editor integrates with Adobe Photoshop via modern Unified Extensibility Platform (UXP) APIs:
UXP architectural features including persistent session metadata, modal tool synchronization, and direct document canvas bindings require Photoshop 27.7.0 or higher.
Document Size & Resource Considerations
Understanding canvas dimensions, Photoshop file formats, and practical hardware limits:
Photoshop Structural Limits: Photoshop Large Document Format (PSB) supports canvas dimensions up to 300,000 pixels in width or height. This is an architectural Photoshop file format ceiling, not a recommended working panorama resolution.
Practical Working Limits: Practical panorama resolutions depend on available system RAM, CPU/GPU throughput, scratch disk speed, and layer complexity. For massive panoramas, ensure your Photoshop scratch disks have ample free storage.
Memory Preflight: If an operation estimates working memory above approximately 1.5 GiB, an advisory prompt allows you to choose between proceeding with full resolution or canceling to free memory.
Full-Resolution Processing Fidelity
A foundational design principle of PanoView Editor is uncompromising image fidelity:
Production operations (Edit This View and Apply View Edits) never downscale or compromise your imagery. Perspective extractions compute at the exact mathematical resolution of the panorama.
Interactive 360 Preview display optimizations remain strictly isolated to the real-time viewer and never alter or degrade source panorama layers.
Edit Document Architecture
Extracted rectilinear views adhere to a verified two-tier layer structure:
Dedicated layer or layer group containing your retouching, clone stamping, and painted additions.
Immutable perspective reference baseline used for mathematical pixel difference calculations.
Unsupported & Out-of-Scope Conditions
To ensure predictable workflow stability, the following conditions are out of scope:
