Re: [Pharo-users] Scaled image

[Henrik Nergaard]

You can use WarpBlt to scale the form.

| input output |

input :=  Smalltalk ui icons iconNamed: #class.
output := Form extent: 128 asPoint depth: 32.

(WarpBlt toForm: output)
                                sourceForm: input;
                                cellSize: 1;
                                combinationRule: Form over;
                                copyQuad: input boundingBox innerCorners 
toRect: (0 asPoint extent: 127 asPoint).

output writePNGFileNamed: 'somefile.png'

Best regards,
Henrik

Ciao,



Morphs have an extent method that you can passes the size as a point in the x@y 
format, there are also width: and height: methods that take simple numbers

            Can explain what i need do  with some code, example ?

            After the scaled i need to save the new scaled image on the disk.

            Thanks
