I found a bug in the delete button of both, Quantizer and GrayDither, which didn't really delete the dither, but I was not able to crash the plugins.
Testing the delete of user dithers, I also found a bug which crash Quantizer when neuquant is used with very small images (less than 400 pixels) but this is not aplicable to GrayDither.

Perhaps your crash is a consequence of the failure in the delete button. :?

Can you test the new version (v 2.6.2) of GrayDither for the crash ? :wink:

Thanks. :D

It still hangs on me. Using PSP X, it throws and unknown error

1. Open any image in PSP
2.- Call the Graydither filter
3.- Select User filters and hit the delete button repeatedly. Of course, several custom filters were displayed.

OK. After reloading, two custom filters appeared (before they were six or more). I deleted one, exit, deleted the other, exit and vòila, there were no more custom filters in dropdown list. Something is still wrong, I presume.

I've published v 2.6.3 with another patch in the user threshold stuff and a new confirm dialog in the delete button.

I hope now the user defined thresholds works as expected. :?:

Thanks for your tests. :D

I had four custom screens. After deleting two of them, it hanged again on me when pressing DELETE button (and confirm) for the third time, although it really deleted the three.

I am wondering if you really need to select the custom screen to delete manually before hitting the delete button. Does it matter?

It seems this issue is going to be a difficult one. :(
Could you please send me the screens ? I need to reproduce your problem in order to identify and solve it.

What do you mean ?
A.- Selecting the pattern in the combo box -> If the selected pattern is the one you want to delete you don't need to select it again.
B.- Selecting "User Defined" radio button -> You don't need to select it.
C.- Selecting "Threshold dithering" check box -> Actually you need to select it to enable the buttons, it seems clearer than maintain the buttons and the combobox enabled.

I will try to describe what I am doing for triggering the error:

1.- Launch Paint Shop Pro X
2.- Open any image for invoking the Plugin, usually Graydither. Tested with Quantizer too.
3.- Several custom filters can be seen. Without touching anything (not pulling down the window either), I hit the delete button.
4.- Current (displayed filter) in drop down list is deleted. List automatically advances and another filter is listed.
5.- I hit the delete button again.
6.- Again, this filter is deleted and it's replaced on the drop down list by another one.
7.- I hit the delete button and PSP X crashed with an unknown error on the output window.

Small update: Trying at work's computer, it didn't hang but, there were just two filters (less than three).

Updated 2: Injected four filters again and deleted them in a row. No hangs so far (this is my computer at work). Could it be related to old-custom-filters leftovers in some way?. I will try at my home computer later again.

Could be.

The user thresholds are stored as subkeys of
HKEY_CURRENT_USER//Software//Ximagic//GrayDither//Thresholds
HKEY_CURRENT_USER//Software//Ximagic//Quantizer//Thresholds

The number of subkeys should match the number of user thresholds.

Could you please review the windows registry of your home computer :?:

It seems registry is synched (empty) now. Maybe some cleaning registry tool messed up with it. I will report back if more hangups occur.

The K-means algorithm (or Lloyd's)
http://en.wikipedia.org/wiki/K-means_clustering
can be used in any n-dimensional space, you just needs a function which give you the distance between two points.

Good day. I have found what it seems to be a bug in Quantizer.

When reducing colours to 4 using Octree (2 passes) and some sort of error-diffusion, I get a one colour image, that is a block of solid colour.

Can anyone confirm? Tested using Corel Paint Shop Photo Pro X3.

Yes, I can confirm it :(

There is a bug in the octree method. The problem appears with less than 8 colors, with or without error diffusion and with or without 2-pass.

Thanks for the feedback, I'll work on this bug asap.
