Overriding the UI for a position marker solution in Document / Layer

[i73]

I need to create a system that will allow a user to position something on a layer and use that as a marker for containing a position for me to get a position with code. My current solution is adding a "Marker" layer to the document and using that as a reference to the position (x, y) where I want the point to be added.

In the perfect World I would like to right click and use a 'Set Marker here' drop down and have them drag around a marker sprite to the position they need, from there I could reference some sort of data object in the scene to get that marker position. That's the perfect example.

Could I accomplish anything like this? Or any other design like piggy backing off another class that can be positioned in a layer like a Anchor to return the position of the class.

I will be extending this to the C++ API, I just need to know what exactly PS can do in terms of what I am looking for.

Thank you in advance!

Hi i73

How about  across hair of two guides? IMHO a better aligning possible than a pixel "marker"

[i73]

Thatnks Pixxxel,

Yes, the Marker should be anything (sprite), that would just overlay the position the user needs.

[pixxxelschubser]

You can't get the cursor position through scripting. But it is possible to get the position of a pixel (but a pixel has a dimension!) or the position of a guide or (as a possible woraround) perhaps the user could set a color sampler and the script reads it's position and set your sprite and will remove the color sampler after then.

[i73]

For me, the pixel idea is a little Hacky, and it won't be able to be seen by the user on a 2k image, and it's not something that a user can move around after it's set so it won't work for me.

Looking at the current tools, thinking I could find some sort of anchor tool. I was messing around with the 'Count tool' :

You can see I added the numbers to the scene, this could serve it's purpose with what exactly I need, do you know if there is something else (That would work better) like this that I could access the data like that?

Or can I access the numbers positions in the scene + their value?

If I have access to that I will go with this solution.

Color samplers are easier in scripting than counter tool

[i73]

Ah, did not know about that, thanks if I have any further questions I'll ask

[SuperMerlin]

Here is some code for the counter tool...

#target photoshop;
var ref = new ActionReference();
ref.putProperty(charIDToTypeID("Prpr"),stringIDToTypeID("countClass"));
ref.putEnumerated( charIDToTypeID("Dcmn"), charIDToTypeID("Ordn"), charIDToTypeID("Trgt") ); 
var desc = executeActionGet(ref);
if(desc.hasKey(stringIDToTypeID("countClass"))) 
var Count =desc.getList(stringIDToTypeID("countClass")).count
for(var z =0; z < Count; z++){
var X = executeActionGet(ref).getList(stringIDToTypeID("countClass")).getObjectValue(z).getUnitDoubleValue(stringIDToTypeID( "x" ));
var Y = executeActionGet(ref).getList(stringIDToTypeID("countClass")).getObjectValue(z).getUnitDoubleValue(stringIDToTypeID( "y" ));
$.writeln( "X= " + X + " Y= " +Y);
}
countClear();
function countClear(){
executeAction(stringIDToTypeID("countClear"), undefined, DialogModes.NO);
};

Thanks Merlin!

One question am I correct with saying that 'classColorSampler' will be for accessing the color sampler?

No.

That's AM-code for count class.

Here is a equivalent for color samplers

// https://forums.adobe.com/thread/2307227
var orig_ruler_units = app.preferences.rulerUnits;
app.preferences.rulerUnits = Units.PIXELS; // Set the ruler units to PIXELS
message="Canvas Width=" + app.activeDocument.width.value + " ,Height=" + app.activeDocument.height.value;
for (var s=0 ,len=app.activeDocument.colorSamplers.length; s<len; s++) {
    var colorSamplerRef = app.activeDocument.colorSamplers;
    message = message + "\nColorSampler=" + s + " ,x=" + colorSamplerRef.position[0].value + " ,y=" + colorSamplerRef.position[1].value;
}
alert(message);
app.preferences.rulerUnits = orig_ruler_units; // Reset units to original settings

Have fun

doc.countItems

Not?

[SuperMerlin]

This gets the position of the first colorsampler.

var mySampler = app.activeDocument.colorSamplers[0];
var xy =mySampler.position;
alert("X = " + xy[0] + " Y = " + xy[1]);

[i73]

Hmmm, I don't have access to the `app.activeDocument` This is in C++ so, off the top of your head would you know if I have access to the class with the 'classColorSampler'?

My code will basically look something like this:

error = sPSActionControl->StringIDToTypeID(classColorSampler, &typeID);
error = sPSActionDescriptor->GetList(result.get(), typeID, &piActionsList);
//Iterate through the piActionsList

Just need to check if the class I am looking for is 'classColorSample`

[r-bin]

As far as I can remember ColorSamples have a maximum of 4 pieces )

10

Please prove it

Yes, I did (in CC)

[i73]

Oh, I don't think this solution would work then, I need access to more than 10. Can I override it more than 10?

[pixxxelschubser]

Unfortunately no. But with the hints of @r-bin and @SuperMerlin you can do the same with the Count Tool (DOM version)

var orig_ruler_units = app.preferences.rulerUnits;
app.preferences.rulerUnits = Units.PIXELS; // Set the ruler units to PIXELS
message="Canvas Width=" + app.activeDocument.width.value + " ,Height=" + app.activeDocument.height.value;
for (var s=0 ,len=app.activeDocument.countItems.length; s<len; s++) {
    var countItemRef = app.activeDocument.countItems;
    message = message + "\ncountItem=" + s + " ,x=" + countItemRef.position[0].value + " ,y=" + countItemRef.position[1].value;
}
alert(message);
app.preferences.rulerUnits = orig_ruler_units; // Reset units to original settings

Have fun

hope this helps

var ref = new ActionReference();
ref.putProperty(charIDToTypeID("Prpr"),stringIDToTypeID("colorSamplerList"));
ref.putEnumerated( charIDToTypeID("Dcmn"), charIDToTypeID("Ordn"), charIDToTypeID("Trgt") ); 
var desc = executeActionGet(ref);
if(desc.hasKey(stringIDToTypeID("colorSamplerList"))) {
var Count =desc.getList(stringIDToTypeID("colorSamplerList")).count
for(var z =0; z < Count; z++){
var X = executeActionGet(ref).getList(stringIDToTypeID("colorSamplerList")).getObjectValue(z).getObjectValue(stringIDToTypeID( "position" )).getUnitDoubleValue(stringIDToTypeID( "horizontal" ));
var Y = executeActionGet(ref).getList(stringIDToTypeID("colorSamplerList")).getObjectValue(z).getObjectValue(stringIDToTypeID( "position" )).getUnitDoubleValue(stringIDToTypeID( "vertical" ));
$.writeln( "X= " + X + " Y= " +Y);
