Release of PhotoFlow 0.2.8


(Carmelo Dr Raw) #16

Thanks Patrick! Vacations are already over since a while, but they’ve been really nice. All the best for you as well!

hi @Dariusz_Duma, just wondering where things are with getting 0.2.8 uploaded. I just tried to install but I’m getting the same errors as above. @Carmelo_DrRaw, sorry I haven’t tried the appimage. I tried one previously but had some odd things happening such as with icons in the launcher bar, so I’ve hesitated since.


Hi Carmelo,
Just wondering if you’ve had a chance to test it out. Thanks.

(Carmelo Dr Raw) #19

Not yet… I had to take a break for personal reasons, but I’ll be back into business in one week from now. Thanks for reminding me!

(Carmelo Dr Raw) #20

Short update on this: I have been able to reproduce the issue, and I’m currently working on a fix. As soon as the fix is ready I will make a new GIMP AppImage package for testing.

(Carmelo Dr Raw) #21

The issue with the photoflow filter plug-in not returning the modified image to GIMP is now fixed. Please download the latest AppImage either from the community built software page or directly from github.

Please let me know if you encounter any further issues.


Thanks @Carmelo_DrRaw . I confirm it now works on my machine. Thanks a lot.


How does the perspective correction tool work? I don’t know how to commit the correction after positioning the control points.

(Carmelo Dr Raw) #24

When the perspective correction layer is selected, the image is not distorted and the control points are shown. As soon as you select a different layer, the control points are hidden and the distorted image is shown.

This is the same logic as the crop tool… I agree this is perfectible, and I have ideas how to improve the interface for next version, but this is how it currently works.

Please let me know if the above doesn’t work for you…


@Carmelo_DrRaw It works as you said. Not very obvious though. I also tried reading your website but back then the tool had a pencil icon to commit the control points. Something new: PF crashes when I activate the crop tool and then click the 1:1 button. Take a look at the log.txt (33.8 KB).

(Carmelo Dr Raw) #26

I have ideas to go back to having a pencil icon, as well as keyboard shortcuts to enable/disable the tool editing mode. That’s something for next release…

Did this happen at the very beginning, or did you already had a crop region selected at a different zoom level?

  1. Open raw file. (Zoom @ Fit image to preview area.)
  2. Introduce crop layer.
  3. Draw crop.
  4. Change zoom to 1:1.
  5. :scream:

Crashes also happen as I zoom all the way out or in. Not sure if the starting zoom level has an effect. I also haven’t taken note of which zoom levels it crashes at and whether this behavior is random, relative or consistent. Having to relaunch PF every time is getting on my nerves :blush:.

(Carmelo Dr Raw) #28

I just found a bug in the way some of the guiding lines were drawn… not sure if this is the issue that is causing the crash in your case, but definitely something that needed to be corrected.

I committed the fix and updated packages should be available soon. Could you remind me which system you are running and from where you are getting the photoflow packages?



I am using on Win7. I remember typing that but may have overwritten it in my previous posts :blush:. Yes, the guidelines needed a fix. Thanks.

(Carmelo Dr Raw) #30

I’ll provide an updated win package tomorrow morning European time.


Additional Remarks

A. Perspective correction could benefit from an option to remove the black edges (i.e., an auto-crop).

B. Thanks for fulfilling my request for a window icon. It looks nice. Photo Flow is one word, right? It would be nice to see the version number in the title; e.g., PhotoFlow 0.2.8.


C. I hope that there will eventually be an icon for the exe as well. As you can see, the icon is currently an unidentifiable window icon.


My workaround is still the same: I generate an ico from the png and attach it to a shortcut of PF; but I have to do this every time I update.


Not a fan of Photoflow workflow, but that is because of inexperience. I do love that you are working on this project. How is the Krita plugin going?

(Carmelo Dr Raw) #33

True, although this will require some work…

I have to see how this is defined under windows… no idea yet.

Concerning the problems with the crop tool, you can find an updated version here. Could you please confirm if the update really fixes the crashes?



Unfortunately, the problem still persists. I will do what I can to help. Just give me some instructions.

(Carmelo Dr Raw) #35

I have been finally able to produce a crash under wine, and found indeed another place where the pixel addressing in the crop module was wrong, which I fixed. Hopefully this is the same problem you observed, and this new version will fix the crashes for you as well.

Please give the new version a try. If you still observe crashes in the crop module (or any other crash by the way), you can try to run photoflow.exe through the gdb.exe debugger that can be found in the same bin folder, and send me the stack backtrace.

The RawTherapee documentation has a very nice description of how to use gdb under Windows and how to generate a stack backtrace of a crash. Adapting the instructions to photoflow should be rather easy, but do not hesitate to ask for help in case something is not clear. The photoflow package I am shipping already contains debugging symbols, so you do not need to download a special version in order to run gdb.
