Script to resize a SELECTION to specific dimensions?

[_Gar_Haywood_]

Sounds like it ought to be easy, but heck if I can figure out how to do it. Is there a way to run a CS3 Photoshop script that will resize a SELECTION (just part of an image, not the entire image) to a specific pixel size (ex. 100 x 150)? I know you can manually resize a selection to a specific PERCENTAGE of its original size, but my script has to automatically shrink image selections of all different sizes down to a given H x W.

Any ideas?

Not good, but you could create a new document from the selection, resize and paste back into a new selection.

If you can make copy of your selection contents then you could record with ScriptListener "New Layer Via Copy" then resize & move this layer. Not tried this.

You will have the same problem Mark as resize on layers is by percentage.
activeLayer.resize( [horizontal] [, vertical] [, anchor]);

Paul, you are quite right bad me didn't look at the OP's question properly. Sorry. If you didn't want the new doc route you could save history step, crop to selection, resize canvas, copy, return to saved history state & paste? or at least I think you could.

Yes that should work Mark, just being playing and this seems to work, needs a selection to be made and the layer must not be the background.
resizeSelection() is called using pixels.

resizeSelection(100,200);

function resizeSelection(horizontal, vertical){



var strtRulerUnits = app.preferences.rulerUnits;



var strtTypeUnits = app.preferences.typeUnits;



app.preferences.rulerUnits = Units.PIXELS;



app.preferences.typeUnits = TypeUnits.PIXELS;



var SB = activeDocument.selection.bounds;



var Height = SB[3].value - SB[1].value;



var Width = SB[2].value - SB[0].value;



var onePixH = 100/Height;



var onePixW = 100/Width;



var newWidth = onePixW * horizontal;



var newHeight = onePixH * vertical;



activeDocument.selection.resize( newWidth , newHeight, AnchorPosition.MIDDLECENTER  );



app.preferences.rulerUnits = strtRulerUnits;



app.preferences.typeUnits = strtTypeUnits;



}
