I want to calculate aspectratio and crop images into that dimention and am using rmagick to crop.
Can anybody help
Try following links to calculate aspect ratio ..
Or if you want maintain aspect ration with Rmagick then.. try this..
"If only the width is specified, the width assumes the value and the height is chosen to maintain the aspect ratio of the image. Similarly, if only the height is specified (e.g., "x256"), the width is chosen to maintain the aspect ratio. To specify a percentage width or height instead, append %. The image size is multiplied by the width and height percentages to obtain the final image dimensions. To increase the size of an image, use a value greater than 100 (e.g. 125%). To decrease an image's size, use a percentage less than 100."
Good Luck ;)
