About the Info panel
The type of data tracked includes:
- colour values (based on a chosen model)
- total ink level
- horizontal and vertical position
- relative height, width, distance and angle
- document colour format and ICC profile
- memory information
The panel allows you to sample from under the cursor or by dragging one or more targets to the page which lets you measure colour at chosen positions. The latter is useful when comparing colours before and after applying image adjustments or filters.
About memory usage
Memory efficiency indicates how well Affinity Photo 2 is dealing with redundancy in its internal representation of open documents. A higher value is better, but methods for improving it are generally undesirable, such as sacrificing editability by merging layers.
Memory pressure indicates how open documents are consuming the memory (RAM) that is available to Affinity Photo 2. When it reaches 100%, not everything that is open can be held in memory and the app begins to use long-term storage – your hard disk or solid-state disk – to hold some data.
Storage is typically much slower than memory and so you may notice decreased performance in this situation. If encountered often, check the RAM Usage Limit option in Affinity Photo 2's Performance settings is set appropriately for your system and needs.
You can use Activity Monitor (Mac) or Resource Monitor (Windows) to check whether memory available to Affinity Photo 2 is constrained by other tasks running on your computer.
The following panel options are available for each sampler:
- Colour Model—Sets the colour model, or total ink level, to be tracked. Select from the pop-up menu.
- Cursor—Samples data under the current cursor position.
- Target—Samples data under a placed target on the image.
