hi,i want to use for exemple a command like this:
" convert rose: -level -25% rose_decontrast.gif "
but instead of "rose:" i want to use my own image name ,for ex :
" convert apa: -leverl -25% apa_deconstrast.gif "
and when i do that it doesn't works and it shows me the following errors :
" no decode delegate for this image format `' @ error/constitute.c/ReadImage/532 "
" mising an image filename 'apa_deconstrast.gif' @ error/convert.c/convertImageComand/3015"
Those error appear always when i want to use insteand of " convert rose: " "convert apa: " or "convert image:" etc

If your input filename is apa.gif then you need to use: Pete

convert apa.gif -lever -25% apa_deconstrast.gif

typo

convert apa.gif -level -25% apa_deconstrast.gif

Thanks Fred. I deleted the wrong character

Pete

Thank you!
