Image Geometry bug about percent

magick syntax:
scale-x%xscale-y% Height and width individually scaled by specified percentages. (Only one % symbol needed.)
Now my problem:
convert a.gif -coalesce -thumbnail 75%x -layers optimize /tmp/imgmogr2-875452210.gif //Height and width both scaled by specified percentage,but according magick syntax is means height should unchange

Try "-thumbnail 75x100%"
[Mod note: as this is a usage question, not Magick++, I'm moving it to Users.]

I know the answer is ok ,but x75% accomplish the purpose desired (only height change)

What version and platform of IM are you using?
On IM 6.8.9.7 Q16 Mac OSX I get:
This is not correct:
convert logo: -scale 75%x -format "%wx%h" info:
480x
360
This is correct:
Code: Select all
convert logo: -scale 75%x100% -format "%wx%h info:
480x
480
This is correct:
Code: Select all
convert logo: -scale x75% -format "%wx%h" info:
x360
I do not know if this is a bug or not. But there is no reason not to add 100% for the height. That is always correct and what you are trying to do.
If you think it is a bug. Please report on the Bugs forum.
