Hi
well.. if nothing was changed it is a bug - from my perspective.
I layer is still not marked as changed, but it is now marked as unsaved
and without datasource.
So, if it is changed (moved), it can be detected and be saved with
SaveDatasets.
so, I don't know.
But what happens now if an image layer is added from sextante
processing? ... because here the warning should pop up first.
Did not make any test with Sextante. Is it using the same loading classes ?

Hi,
Did you take into account that I later fiscovered that "Datasets
have been modified" is not as odd a question as I thought at time?
Image layer can be saved into a Jump GML format and that way it can
be opened back into a project. And this virtual image layer can
consist of several physical image files which are referenced in that
Jump GML file.
Oh,
I should have missed a mail after I wrote the bug report,
You'are right. One can save the image bouding box in a jml file and
the ImageRenderer information in the jmp file, so that the image can
be read again from the project.
So I revert my changes and let it as it used to be, right ?

Hi Jukka,.
- When closing the project with image files a dialogue
"Datasets have been modified" appears. This does not feel
necessary with image layers. I can see that some image layers
can be set to Editable and Selectable state but I do not know why.
This bug should be fixed. It's only a workaround as Image
framework does not work in a very standard way (Layer has no
"DataSourceQuery").
About your second question, I found that most imageFactory
create uneditable layers, but graphic one (png, jpg) is
editable. I let it as is because it actually is editable (you
can move image by move the bounding box). Not sure if it is very
usefyl, but I think you can save the new image coordinates as a
world file.

I had never noticed that there is also an attribute table
connected to image layers. For example for JPEG2000 with
attached world file I can see in the IMAGEERROR colums "Width
(22) and height (-17) cannot be <= 0. For some tiff files I can
see IMAGEERROR 8000 Does somebody know what it mean? On the
other hand, OJ does not open geotiff images which are using
internal JPEG compression but that opening error is not listed
in the IMAGEERROR column.
