unexpected error "convert: geometry does not contain image"

Hello,
trying to execute a command like this:
convert res.jpg '-crop' '100x235+200+102' '-resize' '300x705!' '-crop' '300x300+0+0' test.jpg
I get the error:
convert: geometry does not contain image `res.jpg' @ transform.c/CropImage/507.
but I think it's a bug, in fact if I issue the command in two phases, for example:
convert res.jpg '-crop' '100x235+200+102' '-resize' '300x705!' tmp.jpg
convert tmp.jpg '-crop' '300x300+0+0' test.jpg
everything works fine
Did I miss something?

Add +repage to your command line. Does that fix the problem?

Hello and thanks for your answer, that seems to fix the problem.
Anyway I can't understand why I should use it explicitly, shouldn't it be automatic?
Since the commandline is automatically generated I added a +repage before every operation, it seems to work fine but do you think that could cause any kind of problems?
Thanks,
Alex

If it was automatic, then you lose information that is vital to many other image processing tasks. Especially with regards to layering images, and animations.
See IM Examples, The Missed Image (from a bad crop)
http://www.imagemagick.org/Usage/crop/#crop_missed
for details.

Hi, i read many times about this problem and now i run in for myself, i tried anything to solve this problem but without success
the error : convert: geometry does not contain image `picture.png' @ warning/attribute.c/GetImageBoundingBox/244.
throws when im running this command: convert 'picture.png' -trim -profile 'sRGB.icc' -verbose 'image.png'
the output was: picture.png=>image.png PNG 970x1261=>1x1 970x1261-1-1 8-bit sRGB 2c 0.080u 0:00.079
all attempts by adding +repage without success

1x1 970x1261-1-1
You have trimmed the image to nothing, zero size.

it is not able to save empty images ?

Sadly, no.
I think it should handle zero images, in the same way that arithmetic can handle zero numbers. I think I read that version 7 will be able to do so.

Its probably not difficult to support "zero" images. Can you post a few use cases where you would use "zero" images but fail to work now? What are some specific command-line examples that produce an exception rather than a zero image? We'll use these examples to test our patches to support "zero" images.

Here is a Windows script of some examples, off the top of my head. In each example, I've added a comment about whether I think the result is correct.
It seems IM mostly handles zero images appropriately. It may throw a warning, but not an error. (I note that the OP had a warning, not an error.)
Hence, I mostly retract my comment above: I now think IM does (mostly) handle zero images correctly.

Stand by, we'll investigate the issue.

I don't know what file formats support zero images. If a format mandates a minimum size 1x1, I think IM should be consistent in what it puts there.

PNG specifies a minimum image size of 1x1, but the oFFs chunk allows all of the pixels to be off the page/canvas/screen/whatever. "-repage" prevents the oFFs chunk from being written.

It isn't that simple. No image file format I know of allows a zero sized image.
Really a zero sized image is just non-sensical.
When this happens the 1x1 image, is fully-transparent, as is marked as being a 'NULL' image.
NOTE it is a warning, as it is NOT an error!
GIF animations often will throw up a null image. They are required to hold the timing and meta-data that the original 'frame' contained, but otherwise no-longer take part in the animation sequence. You do not want IM to error abort when this happens. -layers RemoveDups will generally remove Null images correctly for GIF animations.
Examples...
http://www.imagemagick.org/Usage/anim_mods/#crop
Null image handling, removal, and reporting (as in identify output) is an area that could use a little more work.
I have wanted to add a -layers 'RemoveNull' operator, but never got round to it.

I have mostly retracted that statement. IM does handle zero-sized images.

Is it? No more so, I think, than a zero-length string in a program.
