A couple of suggestions

I'm using ColourSpace for about three months and accumulated some suggestions for software improvement. Maybe you will use it, maybe not
1. List of measured points (greyscale, primaries, secondaries) with xyY (and targets) on one sheet (like in HCFR).
2. Showing Average Gamma value in main screen. Currently I have to save profile an go to Profile selection window to check it.
3. Live Update RGB/EOTF/Delta charts during measurements.
4. Constant APL option for Pattern Generator. Very useful for calibrating on LCD TV sets with local dimming turned on.
5. Redesigning Point Info window - currently this windows is very illegible. In LightSpace with seperation lines it was much more clear. Can you improve it? I've attached my custom example.
6. Point Info window - custom sorting options.
7. Point Info window - is it possible to add description for measured point, I mean target name taken from from csv file? It can be similar to hint when you hover mouse point in patches list on measurement window.
8. Point Info window - option for multiple selection for deleting points.
9. Greyscale Delta-E Chart - option to not account luminance error. Very useful during calibrating LCD with local dimming on because Gamma shape depends on selected pattern window size or APL. There's no main rule how gamma curve should be on such case and you have to rely on your experience. So it makes no sense to try to adjust gamma shape. Adjusting RGB tracking is enough.
10. Option for manual clearing charts. It would be very useful. Currently if I need to check another points on CIE Diagram I have to close profiling window and open it again.
11. Measurement window - option for hiding/locking patches on patch list. For example: it would be very useful to lock very dark patches at the beginning of the list (below 3cd/m2) if you run many greyscale sweeps because they significantly slow measurements.
12. On "Hardware Options" tab on "Calibration Patches" default value as "Automatic" for Raspberry PGenerator. Currently every time I run Profiling I have to switch it from "Off" to "Automatic".
13. On Settings tab for "Target Gamut / EOTF" list - add hint for long names because currently they are truncated on the list.
14. Graph options - Gamut Triangle Level - please leave "None" available for selecting after measurements. Gamut triangle borders sometimes disturbs to read edge points.
15. Is it possible to implement displaying "Test Patterns" on Raspberry PGenerator?

To respond to the points that are not future WIBNIs...

1. List of measured points (greyscale, primaries, secondaries) with xyY (and targets) on one sheet (like in HCFR).
Reports provide that capability.
Not sure it would be of any real use elsewhere?


2. Showing Average Gamma value in main screen. Currently I have to save profile an go to Profile selection window to check it.
Average EOTF is shown in the Manual Measure window.

4. Constant APL option for Pattern Generator. Very useful for calibrating on LCD TV sets with local dimming turned on.
This is a function of external TPGs that have that option built-in. It can be seen in madVR TPG for example.

7. Point Info window - is it possible to add description for measured point, I mean target name taken from from csv file? It can be similar to hint when you hover mouse point in patches list on measurement window.
Not really, as 'names' can only be added to custom Preset Patch Lists - not in-built profiles, etc.

10. Option for manual clearing charts. It would be very useful. Currently if I need to check another points on CIE Diagram I have to close profiling window and open it again.
Delete Points in Graph Options does this already.

12. On "Hardware Options" tab on "Calibration Patches" default value as "Automatic" for Raspberry PGenerator. Currently every time I run Profiling I have to switch it from "Off" to "Automatic".
No, it has to be consistent for all Hardware options - and Off is needed to set the various options for other hardware devices before the calibration patches are enabled.

13. On Settings tab for "Target Gamut / EOTF" list - add hint for long names because currently they are truncated on the list.
Was added in the latest release fore the selected option - cannot be added to the actual list though.

15. Is it possible to implement displaying "Test Patterns" on Raspberry PGenerator?
No, as TGPs can only display their own in-built patterns, so the ones in-built into ColourSpace cannot be displayed via any connected TPG.

Thanks for clarifications. But my additional comments:
1. List of measured points - Reports provide that capability. Not sure it would be of any real use elsewhere?
I'm using ColourSpaceZRO, that's why I mentioned it.

4. Constant APL option for Pattern Generator - This is a function of external TPGs that have that option built-in
On Raspberry PGenerator Constant APL plugin by Riccardo Biasi is useless. I have to set 1.5s of Extra Delay Time to work properly. I'm using built-in Constant APL in HCFR and it works flawlessly.

7. Point Info window - is it possible to add description for measured point? - Not really, as 'names' can only be added to custom Preset Patch Lists - not in-built profiles, etc.
Maybe implementing hints only for custom Preset Patch Lists if description exists?

12. On "Hardware Options" tab on "Calibration Patches" default value as "Automatic" for Raspberry PGenerator. Currently every time I run Profiling I have to switch it from "Off" to "Automatic". - No, it has to be consistent for all Hardware options - and Off is needed to set the various options for other hardware devices before the calibration patches are enabled.
Ok. I'm spoiled by HCFR where after selecting Raspberry PGenerator as a source (only once) I've never had to care about it. After every program run PGenerator is selected automatically and I can start measurements without thinking about pattern source settings.

15. Is it possible to implement displaying "Test Patterns" on Raspberry PGenerator? - The ones in-built into ColourSpace cannot be displayed via any connected TPG
Again, I'm spoiled by HCFR which can display its internal patterns.

Sorry, ZRO has limitations.
You would need to upgrade to ColourSpace DPS minimum to get access to Reports, etc.

And you will need to talk Ricardo regarding Pgen and APL, etc.
We can then look to integrate directly, rather than via the Network Server.

Adding options to the Point Info just for user patch sets is not a priority, as the usefulness is limited.
(We have a lot of rather more important developments... but I have added to the WINBI list.)

As I say, the selection of 'Calibration Patches Off/On' is consistent across all TPG.
It is not something we would change for one TPG, especially as PGen presently uses the Network Server, which other hardware also uses.

And I do not understand about Test Patterns?
No internal Test Patters held within calibration software can also be displayed via an external TPG.

In ColourSpace, use the Settings window to set a combination of Patch Size, Position, Stabilisation and Background Colour. These settings will apply to PGenerator, and setting Background to a value of your choice will provide a Constant APL background

HCFR has very limited external test pattern generator connection capabilities. As someone who uses three different external TPG (depending on use case), I understand why calibration patches needs to be disabled by default, as changes to TPG settings (RGB -> YCC, 709 -> 2020, SDR -> HDR, etc, etc) require that the calibration patches are not active for the changes to apply.

Strange, for me if I try this I get the expected warning message, as PGenerator cannot display the test patterns built into HCFR



Of course, you can display them if you use HCFR's internal patch window (GDI), but not via PGenerator. This is no different to the test patterns built into ColourSpace, they will display using the internal patch window



Obviously both of these options require you to connect your laptop/PC with the calibration software to your display directly.

The above is part of the reason that Ted released his LightSpace CMS Calibration Disk on the PGenerator, allowing full control of 100's of reference test patterns directly on the PGenerator using Device Control Template.
