you are welcome, I scale a jpg 4500x3000 to a 640x430 jpg, I will try other formats and I will report

Rich:
Anyone wishing to use  PicFormat  in an  x86  command line only environment, make sure your  imlib2.tcz.dep  file
is up to date. See:

You are aware you changed the aspect ratio from  1.5:1  to  1.48837:1

--- Code: ---tc@box:~$ calc 4500/3000
1.5
tc@box:~$ calc 640/430
1.48837
tc@box:~$
--- End code ---

If you only provide  -w  or  -h  the program will calculate the other value based on the aspect ratio of the input file.

For example:

--- Code: ---tc@E310:~/C_Programs/PicFormat$ ./PicFormat -i ShackleWrench12.png -w 1600 -o ShackleWrench12.jpg
Input=ShackleWrench12.png  Fmt=png  W=800  H=600  AR=4:3
Output=ShackleWrench12.jpg  Fmt=jpg  W=1600  H=1200  AR=4:3  Rotate=0
tc@E310:~/C_Programs/PicFormat$
--- End code ---

or:

--- Code: ---tc@E310:~/C_Programs/PicFormat$ ./PicFormat -i ShackleWrench12.png -h 1200 -o ShackleWrench12.jpg
Input=ShackleWrench12.png  Fmt=png  W=800  H=600  AR=4:3
Output=ShackleWrench12.jpg  Fmt=jpg  W=1600  H=1200  AR=4:3  Rotate=0
tc@E310:~/C_Programs/PicFormat$
--- End code ---

Hi Rich,
I have write 640*430 to semplify, I made this:


--- Code: ---tc@box:~$ PicFormat -i /home/tc/Download/BACCANERA.jpg -o /home/tc/baccanera.jpg -w640
--- End code ---

as your instruction. I'm sorry for the misunderstunding.

Rich:
Hi rullolex
You are allowed to give both  -w  and  -h  if you want to. Just be aware, it will give you what you ask for.
If your input is  800*600  and you ask for  1600*600  your image will be stretched horizontally but keep its original height.
