Problem with Distort Perspective Command

[ahikaz]

Hello, i'm trying to apply this code in my ".bat" file:

Code: Select all

convert checks.png        -matte    -virtual-pixel transparent -distort Perspective '0,0,0,0  0,90,0,90  90,0,90,25  90,90,90,65' checks_pers.png

The problem is that the result is like the original, no trnasformation to see, but i want to have a 3D Cover.
I tried also many examples of the tutorial and they work only the distort Perspective...


PS : I installed this version of ImageMagick : ImageMagick-6.7.2-0-Q16-windows-dll

Thank you.

The command works fine for me in IM 6.7.2.0 Q16 MAC OSX Tiger. But try double quotes rather than single quotes. I am not sure if that is the issue or not as I am not a windows user. so see http://www.imagemagick.org/Usage/windows/

Otherwise it could be your bat file and not the command, so try the command in command line mode by itself to test this.

I think that there are two errors in your command:

1) First of all, single quotes must be substituted by double quotes under Windows, as explained at
http://www.imagemagick.org/Usage/windows/#conversion

2) Second, there are too many commas in your point list. The example given in the "DOS box" at http://www.imagemagick.org/script/comma ... hp#distort is incorrect. The point list should be ordered:
u1,v1 X1,Y1 u2,v2 X2,Y2 ...
i.e. a comma seperates the two coordinates of a point, but not the corresponding image and world point. Perhaps the extras commas do no harm under certain operating systems, but they are inconsistent with the documentation.
