Hi,  
I am using imagemagick and rmagick for image manipulation…

imagemagick version-6.4.4  
rmagick 2.7

I need to create a thumbnail.

```
img = Magick::Image.read(org_img_path)[0]
img.crop_resized(width,height)
img.write(new_image_path)

```

when i used this piece of code in console its cropping correctly…when  
i used inside model or lib or controller its not working.

but if i use crop\_resized! it is working but i need to maintain aspect  
ratio for that image.

If someone knows solutin for this problem kindly help me

with regards  
shiva

any method ending ‘!’ will affect current object  
the remaining methods(except something like pop,shift) won’t affect  
current one  
if you want  
then use it

```
 img = Magick::Image.read(org_img_path)[0]
 img.crop_resized(width,height).write(new_image_path)

```

you can ask this doublt to your colleague like (“najnaR ro  
iallihT”.reverse)

hey guys don’t get angry on me  
if u & ur tl don’t know then you can ask to others(who know).  
don’t discourge other guys who know better then you (like Ranjan and  
Thillai)  
give respect to others also, as a good developer  
i know something about that naskitasky politics in ur  
'etaroproc".reverse  
this is my small advice  
“sorry for my distrub” if “i am wrong”
