Luminance

Question

I have the new version installed for a while. I have gone back to 2.9 because I can not get the historgram to display in Luminance, just rgb. I know to click the rgb, which should click over to luminance....

I think you reported this a while back and I could not figure out why the control would not render properly.  I'm I remembering correctly?

I cannot duplicate your issue.  Both 2.0.9 and 3.0.3 Premium behave the same way for me...Click on 'L' to display the Luminance histogram and click on 'RGB' to display the overlaid RGB histograms.

 

Can you provide screenshots of what you are seeing?

wow, yer good!

 

I kinda think an uninstall and reinstall is in order ?

 

It's not that I'm good, it's because there are very few issues I can not get to the bottom of it and when I get one I tend to remember it... this is one of them sadly.

on the screen shot, why is the ascom screen repeated 3 times? (just like RGB?)

 

It's not repeated, there is 1 for focuser, 1 for filter wheel, and 1 for telescope.  These are 3 different controls.  All 3 are being displayed because he has a high resolution monitor and BYE is maximized full screen... and this leaves enough room do display all of them at once.

Well, the picture is worth 1000 words.  It appears that the histogram plot area is larger than it should be and is hiding the L button, which is just to the left of the RGB button.  I cannot duplicate that on my system.

 

What happens if you resize the BYE window?

The control simply does not render properly.  All item in the control are the right size... but the L RGB buttons are not being rendered completely to the right as they should.  I have a few thousands v3 in circulation right now and this is the only reported occurrence of this odd behavior.

Not just one machine.  I just purchased BYEos and found luminance does not operate on mine etiher.  I'm using Windows 8.1 and Canon T3i.  I click RGB and it just sits here.  Any resolution hints would be helpful.

Dennis,

 

If you are saying that you, too, have a problem with the Histogram Center on the Imaging screen, then it will be difficult to provide "resolution hints". 

 

This issue affects only a few users (you may be number 2) and Guylain has not been able to re-create it or provide a workaround to the one users who has reported it.  I do not believe that there has been a determination that the issue is based on the video resolution.

 

I think that the best approach is if you provide as much information as you can about your installation and what you are seeing.  That may give Guylain additional information that will help him to troubleshoot what is going on and, perhaps, find a solution and/or workaround.

The control does not render properly -or- the L / RGB does not work?

Ok.  Here goes.  I'm using Windows 8.1, canon T3i, and the most recent BYEos software.  I've connected all items to the software; everything appears to work fine.  However, in the Histogram Center, I see the RBG button.  It displays the RGB colors just fine.  However, when I click the RGB button icon (text), it does nothing.  It remains reading RGB and does not switch to Luminance.  It's like the button is inactivated, except there is a very slight, momentary dimming in the text "RGB" when clicked, but returns to normal white text when released.  I've attempted activation in both daylight and non-daylight mode.  No difference in modes.  I've re-installed the software using compatibility mode and it has not and positive effect.  The RGB still does not change to Luminance.  I'd like to use the the luminance switch as that tells me the best histogram of light distribution is striking the sensor.  Colors are good, but doesn't tell me the same thing as gathering the light around the 1/3 to 1/2 half margin of the histogram.

Dennis,

 

Based on my interpretation of your description, what you are experiencing may be due to "pilot error".  The RGB button does not toggle between RGB and Luminance histograms.  It selects the RGB histogram.  So clicking on the RGB button will not cause any change, if the RGB histogram is already displayed.  This behavior has not changed.

 

This is what my Histogram Center looks like after taking an image. Notice that the RGB button is displayed with a light gray background and 2 and L are displayed with a dark gray background.

 

 

Here is what it looks like when I click on the L (for Luminance) button. Notice that the L button now has the light gray background.

 

 

This is working as described in the User Manual that installed with BYE v3.1 RC03.

 

Please let us know whether this addresses the reported issue.

Premium.  Just initiated an uninstall; followed by a new re-install.  Nothing has changed and it is still the same issue.

 

Well... This is the second confirmed case the control does not renders properly... Out of about 8000 copies in distribution. This is odd.

 

Have you tried another computer just as a test?

 

Regards,

No.  Just bought this Toshiba when my other laptop died.

OK, so this is a similar, but unsolved, problem with the Histogram Center not being correctly rendered was previously reported by a single user. The L and 2 buttons are still to the left of the RGB button, but they are being positioned underneath the histogram graph. You can just see the top of the buttons above the right-hand end of the top of the graph.  Guylain was previously unable to figure out why they are being drawn too far to the left for that single, now 2 users.

 

dot net ( AKA .Net Framework) is the Microsoft programming framework that BYE uses.  dts350z was suggesting that perhaps updating the .Net Framework would fix your issue.  If your PC is new (Windows 7 or 8) and you let Windows Update apply Microsoft patches automatically, then this should not be necessary, and perhaps not even possible, since the version of the framework that BYE uses is part of Windows.

 

You said that you uninstalled and re-installed BYE.  Did you, by chance, choose a new and different, or completely empty, directory for the re-install?  If not, that may be worthwhile to try.

 

A workaround for Guylain may be to change the Z-order of those buttons to force them to be drawn on top of the graph.

All good questions.  As a matter of fact, I did install to a new directory and I have automatic updates selected on my machine.  However, the problem still remains.  I see what you mean about the "2 and L" buttons hidden from view. Based your comment, I looked for and saw the very small sliver of the boxes behind the histogram.  I, then, moved my cursor very slowly up to that point ... and ... "shazzam" ... I could make the histogram toggle between RGB and Luminance (as well as interval lines on the histogram).  So, the lesson learned is the functionality is there; just hidden.  I agree with your suggestion to move the "2 - L - RGB" boxes above the histogram and I think that will solve the problem.   I hope a fix can be made soon so I can see the boxes in the dark.  My experimentation was all during the day and finding those pesky boxes at night might prove extremely difficult. Thanks for helping me to understand the problem.  It's fixable; just needs a tweak.
