Making a bitmap area proportional to a value

Hi,

I can arrange elements in a visualization where the size/area of an RTBox is proportional to a specified value, like here:

or I can made all avatars (RTBitmaps) appear into this one:

But I would like to combine both, making the avatars area proportional to a given value and present them in a RTFlowLayout. Is this possible and how?

Thanks,

Offray

Hi Offray,

this snippet may help...

squareResize: aForm to: size

| newForm |

newForm := Form extent: size @ size depth: aForm depth.

(WarpBlt current toForm: newForm)

sourceForm: aForm;

colorMap: (aForm colormapIfNeededFor: newForm);

cellSize: 2;

combinationRule: 3;

copyQuad: aForm boundingBox innerCorners toRect: newForm boundingBox.

^ newForm

of course then you use the Form, and put it into the RT machinery.

best regards

Hi Offray!

Just to make clear I am understanding correctly, you want to scale a bitmap, based on a given metric. Is that right?
