ImageMagic no decode delegate

[cute curtis]

Help, I can't rotate the orientation of a picture using ImageMagic.

Code: [Select]

$ convert IMG_7593.jpg -rotate 90 IMG_7593.jpg
convert: no decode delegate for this image format `JPEG' @ error/constitute.c/ReadImage/562.
convert: no images defined `IMG_7593.jpg' @ error/convert.c/ConvertImageCommand/3273.

Code: [Select]

~$ convert --version

If you need to use it quick here is a web client.

I tried to check this command but don't get much:

Code: [Select]

tc@box:~$ convert -list format
   Format  Module    Mode  Description
-------------------------------------------------------------------------------

* native blob support
r read support
w write support
+ support for multiple images
tc@box:~$

The solution seems here:

Thanks for the references. Does this mean the extension don't work, how did it pass to be included in tiny core repo?

[Juanito]

It was probably included because it was needed to do something and that something worked - if you'd like to investigate further, please go ahead
