Hello
Read first then set density

convert toto.tif -density 150 titi.jpg

thank you i did it but nothing is changed

the option resize needs a minus in front (-resize) also as the other person said, read the image, then -resize, then -density (or see -resample to do both). If you have an old version of IM, then upgrade as it may have problems in these areas.

thank you but still nothing is changed I did this

convert imag.tif -resize 240*320 -density 150 imag.jpeg

Your * should be a x

Code: Select all

convert imag.tif -resize 240x320 -density 150 imag.jpeg

[ircoms]

yes i did it i know it i just write *

thank you

what IM version are you using. perhaps you need to upgrade.

[ircoms]

I use ImageMagick-6.5.0-10

[fmw42]

That is about 30 versions behind the current one. Perhaps it had a bug that has since been fixed. Recommend upgrading and trying again.

By the way how are you determining that the quality or density is not as good as you want it?
