2.6.2.1 Image Scaling

Scaling an image results in changing the dimensions of all the layers at once, while simultaneously stretching or squeezing the image contents to fit. The function Scale Image , found in the Image:Image menu, is the tool that accomplishes this. Figure  2.15(a)

  
Figure 2.15: Image Scaling
Figure 2.15

shows an example image, and Figure  2.15(b) shows the Scale Image  dialog. The new width and height of the image can be specified in pixels or as a percentage of the current dimensions. The default is to scale the two dimensions proportionally, but this can be changed by toggling the chain icon next to the Ratio X and Y entry boxes. The result of scaling down the image shown in Figure  2.15(a) by 75% is shown in Figure  2.15(c). The result of scaling it up by 125% is shown in Figure  2.15(d).
