Memory Preflight

Section 01

Why Memory Preflight Exists

When working with high-resolution spherical panoramas, operations such as extracting a perspective patch or applying reprojected pixels back into equirectangular space require allocating temporary working buffers. Large pixel dimensions, 16-bit color channels, and complex projection mathematics can temporarily create substantial memory demand inside Photoshop.

Proactive Workflow Protection

Instead of initiating a heavy calculation blindly and risking unexpected system slowdowns or Photoshop resource exhaustion, PanoView Editor performs a fast mathematical preflight check before demanding operations begin. This allows you to evaluate your current working environment before memory is committed.

Section 02

The ~1.5 GiB Advisory Threshold

When the estimated working memory required to complete an operation exceeds approximately 1.5 GiB, PanoView Editor displays an advisory notification modal.

Important Distinction: Working Memory vs System Limits

The ~1.5 GiB threshold is an estimated working-memory threshold for the immediate operation. It must not be confused with:

•Not a Maximum Document Size: Panoramas far larger than 1.5 GiB on disk can be edited successfully.
•Not a Minimum System RAM Requirement: It represents buffer calculation demand, not computer hardware specifications.
•Not a Failure Threshold: It does not mean Photoshop will crash; it is an advisory prompt giving you conscious control.

Section 03

What the Warning Means

When the memory preflight dialog appears, understanding its exact message prevents confusion:

What It Does NOT Mean

The panorama is unsupported or corrupted.
The file is too large to process.
PanoView will silently downsample your image.
An error or operation failure has occurred.

What It Actually Means

The requested operation will require substantial memory.
Photoshop will allocate sizable processing buffers.
You have the opportunity to save work before proceeding.
You maintain complete control over how to proceed.

Section 04

Your Two Choices: Cancel or Continue

The preflight dialog provides two explicit pathways:

PATH A

Cancel

Stops the operation immediately before heavy memory allocation begins. The panorama remains open in its existing state, allowing you to save other files, close unused documents, or free system resources before retrying.

Result: Zero memory committed

PATH B

Continue

Instructs PanoView Editor to proceed with the requested operation at full resolution. Continuing does not reduce image resolution or compress pixel fidelity; full-resolution quality is maintained throughout.

Result: Full-resolution operation proceeds

Section 05

Before You Continue

If you choose to click Continue, following these general workflow habits ensures the smoothest execution:

Save Open Work First: Press Cmd+S / Ctrl+S to save your master document and any open tabs.

Close Unused Large Documents: If you have other high-resolution Photoshop files or previous session tabs open, close them to free working memory for Photoshop.

Avoid Concurrent Heavy Applications: Minimize running other memory-heavy software (such as 3D rendering engines or video editors) simultaneously during demanding panorama operations.

Cancel If Under Heavy Load: If your system is already exhibiting heavy paging or memory pressure, click Cancel, restart or clean up your environment, and resume when resources are available.
