Hello,
In a multi layer situation I have a need to resize the background (Layer 0) to a new size and resize multiple user selected layers proportionally to a size entered by user without spoiling the arrangement between selected layers.
For example there are three layers - Layer 0, 1 & 2.
Now the user will reduce the size of Layer 0 by entering its size in provided interface. Once the size of Layer 0 set the user will select the Layers 1 & 2 and enter a new size in the provided interface. These Layers 1 & 2 should be first resized to the entered width and height as a group (one single virtual object) and automatically aligned to the center of Layer 0 maintaining the arrangement between Layers 1 & 2.
I have tried to use the functions:
- LayersRepositionAll
- LayersAlign
- LayersSizeAll (this only works with percentage so probably I am not able to use it properly as the users are entering absolute width and height values)
TIA

Hi Yogi,
maybe you can use this:
// Enlarge all layers vertically and horizontally by 10 pixels
ImageEnView.LayersRepositionAll( 10, 10, False, True );

Hi Yogi
For complex movement like this, you should just iterate through the layers setting PosX, PosY, Width and Height.

Klaus & Nigel,
Thanks for your hints.
Actually I was hoping that there was such a function as if a user interactively Resizes multiple selected layers they all get resized properly and also relocated as expected.
TIA
