have prefix in output file name

[edjayks]

I tried to convert a number of files like this:
convert -size 660x580 -depth 8 "C:\path...\*.jpg" "C:\path...\%d.png"

path... is the path to the file location.

For example, there's 2 file, 1.jpg and 2.jpg,
after conversion, the file would be named d-1.png and d-2.png.

Why is "d-" added to the file name? How do i remove or prevent it?

Thanks.

*additional info: this problem only happen when the command is in a windows batch file. If i type in the command manually into command prompt, i could get 1.png and 2.png as the output file name.

That suggests that the problem is in the interpretation of the percent sign. I think in a batch file you have to double the percent.
Try this sort of thing:

Code: Select all

convert -size 660x580 -depth 8 "C:\path...\*.jpg" "C:\path...\%%d.png"

Hi el-supremo, thanks for the help. It works fine after doubling the percent.
Thanks.
