True Preview

[NotMyFault]

Currently, Affinity Photo does not provide a absolute trustworthy preview of the current document.

• For any zoom levels not equal to 100%, you get misleading rendering of noise and unsharp mask filters
• With View Mode "Bilinear", you will always get false rendering on pixel level at hard edges
• Even with zoom level 100%, you could get get false rendering when dealing with pixel art
• For zoom level below 100%, you could get completely wrong colors caused by resampling (same bug report above)
• Many live filters can introduce rendering artifacts at any zoom level, including 100%, leading to severe deviations from final result, especially when combined with blend mode "difference"
• The false color by resample issue could bite you at almost any zoom level except 400% and integer multiples of 400%

 

The only way to get a reliable preview of your document is to either

• Export - leaving the application
• Merge visible - introducing superfluous temporary layers, must be created on top of layer stack and deleted after use.

 

Even the export preview 100% function is currently broken on iPad.

To overcome all these issues, it would be helpful if Photo would offer an "absolute trustworthy preview" move, similar to Designers View Modes.

Requirements:

• No color artifacts (false colors) by resample in case of zoom <100% (use color-correct average, not false sub-sample)
• 100% accurate rendition of result
• ability to zoom to any level (at least -8x to + 8x)
• Ultimate priority on accuracy, no priority on performance.
• Selectable options to deal with non-opaque pixels (color of matting background)
• Regular keyboard shortcuts and mouse actions to zoom / pan
•
