How to convert an image and also generate thumbnail from it

[yogiyang]

I want to convert any supported format image to JPG and also generate a thumbnail of max size 200x200 pixels.

Currently I am giving two commands for this:

Code: Select all

convert "12 x 36\010 copy.jpg" c:\up_temp\001.jpg

and

Code: Select all

"convert.exe" -define jpeg:size=500x180 "C:\up_temp\001.jpg"  -auto-orient -thumbnail 200x200   -unsharp 0x.5  "c:\up_temp\tn\00001.jpg"

The first command is generating JPG which are bigger than the original file so what can I do to compress the generated file without any quality loss?

How can I convert above two commands to one single command so that both things are completed in one single command?

TIA

You don't need the first command. Just put the original file name in the second command.

Code: Select all

"convert.exe" -define jpeg:size=500x180 "12 x 36\010 copy.jpg"  -auto-orient -thumbnail 200x200   -unsharp 0x.5  "c:\up_temp\tn\00001.jpg"

Thanks for your assistant.

This only creates the thumbnail. The the file created when using my first command is not getting generated here.

How about:

Code: Select all

copy "12 x 36\010 copy.jpg" c:\up_temp\001.jpg
