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)

ok thanks mokkai. wht is the difference bwn wht i wrote and wht u have send

eg: img.crop_resized(width,height) img.write(new_image_path)

and wht u have sent

img.crop_resized(width,height).write(new_image_path)

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"
