Set specific layer to be selected in script

[riggsdp]

Is there a way to set a specific layer name or number to be selected in a script? I need to have the first layer turned on or off, no matter what layer is currently selected.

I've already created a script that turns a layer on or off if I click on a bound button but it will only do it for a layer that is the same number of layers above the current layer as when I created the script.

Perhaps you could use App.Do( Environment, 'SelectLayer', ... in your script to select the layer.

Two suggestions:

1. Look at some of the scripts that are supplied with Paint Shop Pro. The location varies with each version, but for X3 you may want to start with C:\Program Files\Corel\Corel PaintShop Photo Pro\X3\PSPClassic\Languages\EN\Scripts-Restricted\Artistic. Several of the supplied scripts work with multiple layers. Use these to get ideas for your new script.

2. Start recording a script and select the layer you want with the user interface. Save the script, examine it, and copy/paste into your new script.

I've tried all that and the only thing I can see where it determines the layer is by selecting where the layer to select is in relation to the layer that is currently selected.

So, if I have three layers and start recording with the first layer from the top selected, then select the third layer, then the first layer, then second layer, the script indicates to select 0,-2, which is the layer two down from the selected layer, then 0,2, which is two layers up from the layer I just selected, then 0,-1 which is the layer one down from the layer just selected.

I can't find a way to select the very first layer at the very top of the listing no matter what layer I'm currently on.

If I have layer 256 selected, then I need it to turn layer 1 on or off, if I have layer 36 selected, I still layer 1 turned on or off.

To select the very top layer simply have your script select the base layer, add a new layer, arrange that layer to the top, then delete that layer. You now have the top layer selected by default. If you just add a layer without selecting the base layer first then the script will come up with a fault if you already have the top layer selected.

I'm sure there are other solutions as well.

Most of the time you won't want to be selecting a specific layer unless you've made the layer and then it's a simple up or down scenario. So there isn't a special command for it but you can use the SelectLayer() command with the strict setting turned off to force Paint Shop Pro to approximate the topmost or bottommost layers.

The document "Scripting for Script Authors" gives a more detailed example of selecting layers so I suggest you read it. If you don't have it you can download it here: http://corel.custhelp.com/app/answers/d ... stallation

This is a direct quote from that document on some ways to select specific layers.

To select the bottommost layer: (9999, -9999, [], False)
To select the topmost layer: (9999, 9999, [], False)
To select the topmost element of the current group: (0, 9999, [], False)
To select the topmost child of the current layer (0, 0, [9999], False)
To select the next layer up: (0, 1, [], False)
To select the next layer down: (0, -1, [], False)
To select the parent layer: (1, 0, [], False)

Thanks, I'll try the one to select the topmost layer. I've also downloaded the scripting help file.

Much appreciated, dar
