Description

There needs to be a set of flags that import/export filters can export to show they can e.g. save layers, save to a certain colorspace and so on. Then there needs to be a central class that checks those flags agains the actual image and composes a warning message that can be shown to the user.

Edit: I cannot open any old kra files anymore...

Edit2: Of course, clean install fixed this. I think it's imperative to mention that when merging, because otherwise people will be confused.

Saving a single layer image with a projection background gives the following:

The following files have the same issue:

Ora
Gih
qml
r16 heightmap
r8 heightmap
sprite scml

Your image contains layers with the color model RGB(I18N_ARGUMENT_MISSING) and channel depth 8 >Bits(I18N_ARGUMENT_MISSING) which cannot be saved to this format. The layers will be converted.

with the terminal saying

Tiff gives:

Error: cannot save this image as a TIFF image. Reasons:

EXR cannot save images with color model RGB and depth 8 Bits. The image will not be saved.

EXR cannot save layers with color model RGB and depth 8 Bits. The layers will be skipped.

On an animated file, CSV says:

You will lose information when saving this image as a CSV document. Reasons:

The image contains layers of unsupported type Clone Layer. Only the rendered > > * result will be saved.

The image contains layers of unsupported type Filter Mask. Only the rendered result will be saved.

The image contains layers of unsupported type Transparency Mask. Only the rendered result will be saved.

This image has animated layers. Animation cannot be saved to this format.

csv can save animation... Not curves, but it can save frames...

Also, I have a empty entry/space under ora in the file type filter(using unity)

Also, got a crash in the layerdocker when making a new image after the exporting fun above??? Not sure if related.

I also got the same warning message for Tiff which Wolthera reported. I believe even if a file format doesn't support layer it should allow me to save at-least a flattened file, like it does for png ( of course by giving a warning)
While exporting to png user shouldn't be shown the save to krita file checkbox as exporting means user already has a kra or psd file with layers, showing a warning while exporting is also not necessary in my opinion.
lastly I feel that the way the warning are shown is in a bit unexpected way. I mean I as a user would not expect a warning in a dropdown box. may be a small line with highlighted color background to draw the users attention and when he hovers the mouse we can show him a more detailed explanation in a tool tip. ( I don't know if this is a good solution). One similar warning I have seen in krita is input boxes. they turn red when i enter wrong input may be it will be good to continue similar color coding and method to alert user. In this last point I may be nitpicking as it is not really hindering my save experience.

Also, autosave is confused here:

Could not save /home/krita/.krita-7545-document_0-autosave.kra
Reason: Internal error

getting crash while saving as png. below is the back trace

I'll check the crashes. I don't think making the warning a tooltip is a good idea, since I suspect users will want to select, copy and paste warnings, which is impossible with a tooltip.

All remarks should be fixed/implemented now.

I still get the autosave message. It's weird, one half of the time the autosave works(and I have an autosave of my current image), the other half it seems confused as indicated by

Could not save /home/krita/.krita-17575-document_4-autosave.kra
Reason: Internal error

Edit: for what it is worth, the terminal spits out this:

QFile::copy: Empty or null file name

I noticed a number of autosave bugs, one of them was that the autosave files were removed after saving, another that the autosaver timer was reset wrongly. But I haven't seen this error. What kind of image is this -- what's in there? Does the same set of messages appear when saving that image to a named .kra?

The QFile::copy is another issue, that was a bug in the KoZipStore desctructor that didn't check whether the store was created for saving to a stream.

The empty entry in the file dialog is gone, too, now.

It's a single raster layer in an image with a canvas projection color. That's nearly as basic as it can get.

Here's a file

It told me it couldn't autosave, but there seems to be an autosave none-the-less, but the autosave is a backup???

And I have this in the terminal when the autosave botches:

I got a really weird crash in this branch but I am not sure it's related to any of the refactoring? I was just trying to move the layer with the move tool:

I think I may have found something akin to the cause of the autoave bug: My file name is saved, regular simple file. After a while it becomes autosave.filename.kra, and only after that it starts bugging out, at which point the name in the titlebar becomes nothing. So maybe the autosave mechanism is using the wrong saving method?

I've seen exactly this crash flit by on bugzilla as well, in https://bugs.kde.org/show_bug.cgi?id=371124 among others.

This crash has been fixed already in the impex branch.

Hm... Could be, though I cannot reproduce it at the moment. I made some fixes recently to the autosave mechanism, though.

I still have problems with autosave for a build after 6pm today. Could you maybe add some more diagnostics for the autosave into the terminal so I can give actually useful feedback on this?

Hm... I've some more debug info. If I now create an image, save, modify, wait for autosave I get this output:

Ok, say hi to vaguely useful fedback. In the following, I got 4(!) times the warning window. Eventually it did manage to save. Before it managed to save the title bar only showed the title, not the filename, and finally, after it saved, it showed the title, and then autosave.filename.kra.

I also see that you're still getting those message errors -- which I also don't get, and which I don't understand how they still can happen.

I've added some extra asserts, but I'm still really puzzled because even an empty string would count as an argument, and this looks like the arguments really aren't there in these lines:

libs/impex/ColorModelPerLayerCheck.h: m_warning = i18nc("image conversion warning", "Your image contains layers with the color model %1 and channel depth %2 which cannot be saved to this format. The layers will be converted.").arg(m_ColorModelID.name()).arg(m_colorDepthID.name());

and

libs/impex/ColorModelCheck.h: m_warning = i18nc("image conversion warning", "The color model %1 or channel depth %2 cannot be saved to this format. Your image will be converted.").arg(m_colorModelID.name()).arg(m_colorDepthID.name());

Attaching a file that shows that the problem with autosave is caused by LOD not allowing the document being locked.

While we work on a png image, Krita shows png save options dialog when autosaving, the autosaved file is in kra format but it shown options for a png image. I think this dialog shouldn't be shown.

I fixed that this morning.
