convert TIFF to a .jpg

Post by craigmc »

Hi,

I'm getting error below when trying to convert tiff files although they display perfectly in MSOffice Picture Manager I fear they may be corrupted or not valid in some way. Version info is:- ImageMagick 6.5.4-10 2009-08-08 Q16. Is there a way to get round this error?

C:\Op Pictures>convert 177-1.tif 177-1.jpg

the first, I believe are just warnings and do not affect anything. just fields not supported in the head. The last two seem to indicate that you do not have the jpg or tif delegate libraries installed or you have directory and/or permission problems.

type the following

convert -list configure

see what is listed under DELEGATES as per my system

DELEGATES bzlib fftw fontconfig freetype gs jpeg jng jp2 lcms lqr openexr png tiff x11 xml zlib


anything not listed that you want, must be installed via the delegate library and then IM reinstalled
