yes it is saved on my pc as PNG: http://oi67.tinypic.com/287hjxe.jpg

i guess it is tinypic that convert format.

thank you very much for support

Hi thank you very much. ok i see you compared the same image (2k3me2.jpg) but this is one of the 2 images i had to compare. Anyway i have obteined the score comparing the 2 pics and it is 0 : http://oi63.tinypic.com/2hdwfi1.jpg in addition this is the PNG difference: http://oi63.tinypic.com/2rdkg7b ...

i do not understand probably. but look at this: http://oi67.tinypic.com/2hy8exd.jpg the transparent pics you see (miniatures) are all differences saved as JPG, and they are transparent in the miniature as well... not only when i open [cit] The important thing is that there is no (default red) color ...

ehm no it is impossible i've always saved difference pics as JPG and pics alwars were transparent... this happens only with these 2 pics downloaded from imageshack (and saved as JPG) . in addition i underline that only miniature is colored: when i open it i see transparent pic anyway considering ...

to be precise: i have 2 pics that i want to verify if equals (like the pic linked above).pics are uploaded on imageshack so i download them on my pc and i compare the pics using imagemagick (compare pic1.jpg pic2.jpg dpic.jpg). Now: i tried to save the difference as PNG and the difference (PNG ...

hello... im sorry. version: imagemagick 6.9.9-33 Q16 x86 2018-01-06 this is the image: http://imagizer.imageshack.us/a/img922/6240/2k3ME2.jpg if i upload 2 times this pic (but i think others as well) on inageshack, then i download them on my pc and use: compare pic1.jpg pic2.jpg dpic.jpg the result ...

hello, sometimes it happens that when i compare 2 equal pics (by using compare) the difference is showed with normal colors in the folder. but then, when i click on it and the pic is open, it appears 'transparent' as normal for equal pics. what does it mean? ps.it happens when i download the ...

ok thanks now i understand better!
anyway so we can say that it does not exist a way to estabilish if the differences are caused by a rotation or not, right?

this is whats happens using difference in GIMP: http://oi63.tinypic.com/28b7lud.jpg

One file has an embedded profile, and the other doesn't. So how are you comparing them? i am not sure i am understanding what you mean... anyway i used the syntax compare file1.jpg file2.jpg diff.jpg... It may look black, but it isn't, even using just 8-bit Gimp, whether or not we convert them to ...

hi. i think i solved the problem using GIMP. I used layer mode difference applied to the two images and the result is total black. so i think there is no rotation. i have just one more question. GIMP says that the two images are identical, that is the pixel values are identical. But imagemagick ...

yes it is correct. the images look identical. but the second one has a minor quality. i want to estabilish if the second one has a little rotation (that could not be visible to the naked eye)

I will explain better. I have for example two images, the previous one : http://oi67.tinypic.com/rkdgyr.jpg and a manipulated version of the previous one: http://oi64.tinypic.com/x3ekr8.jpg . If i use compare it shows red points because the second one has a minor quality compared to the original ...

Hi,
for example this: http://oi67.tinypic.com/rkdgyr.jpg
and a manipulated copy of this image. I just need to check id the manipulated one was rotated of a small angle.

thanks in advance

hi,
i use imagemagick 7.0.7.21 for windows
i should verify if an image was rotated of an angle from the original one. the two pics may have different quality because of manipulation. my question is: is it possible to veryfy if the manipulated one was rotated?

thanks
