Unable to run convert command in CentOS using (ImageMagick)

Question

I am new to ImageMagick and I am simply trying to run convert command at Command line which is as follows:

convert '/home/674390/Desktop/rose.jpg' '/home/674390/Desktop/rose.png'

Getting an error message:

convert: unable to open image /home/674390/Desktop/rose.jpg': No such file or directory @ error/blob.c/OpenBlob/2643. convert: no decode delegate for this image format/home/674390/Desktop/rose.jpg' @ error/constitute.c/ReadImage/555. convert: no images defined `/home/674390/Desktop/rose.png' @ error/convert.c/ConvertImageCommand/3144.

Please help.

My Operating System is CentOS.

There's three errors involved with your convert command.

convert: unable to open image /home/674390/Desktop/rose.jpg': No such file or directory @ error/blob.c/OpenBlob/2643.

This means exactly what it says. There is no file at that path, or you do not have read permissions to access it.

convert: no decode delegate for this image format/home/674390/Desktop/rose.jpg' @ error/constitute.c/ReadImage/555.

This message is informing you that you'll need to install libjpeg to work with this file format. See ImageMagick Delegates for resources. You can also verify what your system can work with by running the following commands.

convert -list delegate | less
convert -list format | less

Finally

convert: no images defined `/home/674390/Desktop/rose.png' @ error/convert.c/ConvertImageCommand/3144.

As the first image could not be opened, convert now believes the distention file is the source file, and attempts to open it for reading. And so, a message identical to the first one is displayed.
