Image resize through api

[Divya S]

I am trying to push a image to confluence by resizing it , I face like I can't push the image to confluence if i use 

<ac:image ac:height="20" ac:width="30" >
<ri:attachment ri:filename="{filename}"/>
</ac:image>

Through this code I can push images 
<ac:image>
<ri:attachment ri:filename="{filename}"/>
</ac:image> 

Is there any possible solution for this one?

 <ac:image ac:width="{pixel_width}" ac:custom-width="true">
