Biagio,

Imagegen is what you need for resizing images http://our.umbraco.org/projects/website-utilities/imagegen

I know. It was an old knowledge, but some features that I need, are not free like upper API. There was an old project on CodePlex ( DNAIDE http://dnaide.codeplex.com/ ) , but it stopped.

Good News from IIS world...

I'll give a try to Dynamic Image Resizing Module

http://www.iis.net/community/default.aspx?tabid=34&g=6&i=1916

Features

Command Reference

• width, height - force the width and/or height to certain dimensions. Whitespace will be added if the aspect ratio is different.
• maxwidth, maxheight - fit the image within the specified bounds. (Most often used)
• crop=auto - Crop the image the the size specified by width and height. Centers and minimally crops to preserve aspect ratio.
• crop=(x1,y1,x2,y2) - Crop the image to the specified rectangle on the source image. You can use negative coordinates to specifiy bottom-right relative locations.
• rotate=degress - Rotate the image.
• bgcolor=color name| hex code (6-char). Sets the background/whitespace color.
• stretch=fill - Stretches the image to width and height if both are specified. This is the only way to lose aspect ratio.

• flip=h|v|both - Flips the image after resizing.
• sourceFlip=h|v|both - Flips the source image before resizing/rotation.
• paddingWidth=px & paddingColor=color|hex. paddingColor defaults to bgcolor, which defaults to white.
