Possible bug in using cut-and-paste of images.

Don Rozenberg
Hi,

I am new to gimp and have been trying to use gimp to position and size
images on a letter size canvas for printing using the method I have
used with Photoshop Elements. I am running gimp 2.7 in Knoppix/Debian
Linux. (I saw the same behavior gimp 2,6.) I used apt-get to do the
installation.

I think that I may be seeing problems with both the resize tool and
layer manipulation.

The steps I go through are:

    1. Create a new image (image A) using the US-Letter template. This
       is the image I will be printing.

    2. Open an image (image B) I wish to add to image A.

    3. Make Image B active, Edit->Copy.

    4. Make Image A. Edit->Paste.

    5. Select scale tool and drag a corner to enlarge the image.

    6. Click on the scale button.

I get a partial image the same size as the original one I tried to
resize but it only containing a corner of the enlarged image.  I think
that this is a bug.

I tried this with gimp 2.7 on Windows XP and it seemed to work as I
expected; i. e., the pasted image was enlarged when I clicked the
scale button.  This differing behavior suggests that this is indeed a
bug in the Linux version.

Also, if I open, say, three images and copy-and-paste them onto a
fresh letter-size image, I was expecting to see 4 layers, a background
layer and three floating selection layers as I get when doing this in
Photoshop Elements.  What I see instead is a background layer
containing the first two images I copy-and-paste'ed plus one floating
selection layer.  Is this the correct behavior?  I am surprised by the
'flattening' of the background and the earlier images. It happens with
both the Linux version and the XP version.

try right clicking on the image with the layer that you want to scale
highlighted in the layers dialog.  then follow the menu:
Layer -->Scale Layer and feed it a number.

i have only used gimp on linux; and only on that highly suspicious open
to judgement and probably insecure gnu/linux at that.  also, i have been
using gimp for (possibly) way too long now and have yet to try dragging
a corner.  if you think about it, a proper scaling should use some
numbers to be certain that you get a correct resizing.

yes, it is not the best behavior, it is the correct (according to how
the software has been written so far) behavior -- they are claiming
(still) to be uncertain about how to handle this situation.

the situation is this: the layer floats until you anchor it or make a
new layer of it.  anchoring it will fix it to the highlighted layer.  if
you only have one layer, that will be the hightlighted layer.  if you
make a new layer (Layer -->New Layer) it will appear at the beginning of
the stack.  if you leave it floating and paste a new layer into the
image, it (by default) will anchor it.  

TheGIMP uses layers much more naturally than Photoshop.  the biggest
difference between the two different softwares is that TheGIMP uses
layers and Photoshop uses selections.  since photoshop5 and gimp-1.0
they have both started to catch up to each other as far as layers vs
selections go.

here is a secret of the way computers deal with pixels:  selections are
a special case of layers.  that being said, Photoshop hides this from
the user making some things easier.  TheGIMP does not hide this so much
and this gives the user more control, particularly at the point where
things actually happen.

btw, for a photoshop user you must have missed something in how to ask
questions rudely.  for this, i thank you.

welcome to gimp, may the transition be as easy for you as it has been
for me to keep using it.

You probably confused some number because (last time I checked) there
was no gimp 2.7!
Gimp 2.3.1 is the latest unstable version. And gimp 2.2.7 is the latest
_stable_ version.

This doesn't happen in my gimp. I have 2.2.3 in linux. Try doing
Image>Scale Image on Image B before you copy and paste it to image A.
This might help.

If you think it's a bug then (if you can) please go to
http://bugzilla.gnome.org/simple-bug-guide.cgi

And submit a bug by doing this:
First creating a new account (I know this could be a pain but it helps
the developers to track you down if they need more info from you).
Then login.
Go to above link.
On the first page choose appropriate option and then go to second page
(by clicking "next page" button).
Here make sure you put a check mark on "Click here to also show
applications not part of the GNOME 2 Desktop"
Then on the selection list select "GIMP" then go "next page" again.
Then on this page the component is likely "tools" according to your
description. So choose that and move on to next page.
On this page you choose bug "severity" and move on.
Then you choose gimp version (in your case I think it's 2.2.7 and _not_
2.7 :)
Then _finally_ you fill out the details.

Yes. I think the developers (God bless them) intended for this to
happen. When you copy one image into another (Edit> Copy then
Edit>paste), gimp does not automatically create a layer for you but
rather gives you a temporary layer called "Floating Selection (Pasted
Layer)". Now you have to options, one being "Anchor Layer" (access this
by right clicking on the floating layer) and the other "New Layer".
Anchor layer merges the floating layer and the layer under it, whereas
new layer puts the floating selection in a new layer. It turns out (I
just tried it) if you paste and you have "Floating Selection" layer then
the action that will be taken by gimp is make the "anchor layer".

Thanks for helping out The GIMP Don, and I hope you like it.

If I am understanding you correctly, I get the same behavior.  I have
thought (I still think) it was a problem with me -- with my not being able
to figure out how to do this correctly.

I have a large photo, I want to make it fit a smaller space, I scale,
type in numbers or drag a corner, and I get a corner portion of my
original photo, writ huge.

Are you sure you're performing the operation correctly?  Seems to me
we're having the same problem.

I am not sure I understand both of your descirptions, but I had to add
two steps to obtain the desired result:
4b - create a new layer for the paste floating selection (new layer
button in the layers window)

5-Select scale tool, set the "Affect" option in the tool option to
"Transform Layer".

I hope this can do the trick for you.

Best regards,

Olivier.
