Brush Roundness + Angle

[polpla]

I am working on a custom HTML panel for controlling brush parameters to improve my workflow.

By using the ScriptListener I was able to get a simple script to change the size of the brush dynamically.

Unfortunately, ScriptListener does not update the script output when I change the brush roundness or the angle.

Does anybody know the right parameters? I have been trying to figure them out with the documentation but all I got was a headache.

Here is the js for rotation (what I am looking for is the equivalent for both roundness and angle):

function setBrushSize(size) {

  var idSet = charIDToTypeID( "setd" );

  var idNull = charIDToTypeID( "null" );

  var idBrush = charIDToTypeID( "Brsh" );

  var idOrdinal = charIDToTypeID( "Ordn" );

  var idTarget = charIDToTypeID( "Trgt" );

  var idTo = charIDToTypeID( "T   " );

  var idBrushSize = stringIDToTypeID( "masterDiameter" );

  var idPixels = charIDToTypeID( "#Pxl" );

  var desc1 = new ActionDescriptor();

  var desc2 = new ActionDescriptor();

  var ref1 = new ActionReference();

  ref1.putEnumerated( idBrush, idOrdinal, idTarget );

  desc1.putReference( idNull, ref1 );

  desc2.putUnitDouble( idBrushSize, idPixels, size );

  desc1.putObject( idTo, idBrush, desc2 );

  executeAction( idSet, desc1, DialogModes.NO );

}

Thanks in advance!

Ok, after some more research I found the name of the parameter that I believe would change the angle of the brush: "brushPoseAngle".

I found the name here:

http://ps-scripts.cvs.sourceforge.net/viewvc/ps-scripts/xtools/xlib/PSConstants.js?revision=1.18

Using this reference I try to create a function that would modify the brush angle, but I still have had no luck.

Here is my failed attempt:

function setBrushRotation(deg) {

  var idSet = charIDToTypeID( "setd" );

  var idNull = charIDToTypeID( "null" );

  var idBrush = charIDToTypeID( "Brsh" );

  var idOrdinal = charIDToTypeID( "Ordn" );

  var idTarget = charIDToTypeID( "Trgt" );

  var idWhat = charIDToTypeID( "What" );

  var idBrushAngle = stringIDToTypeID( "brushPoseAngle" );

  var idAngle = charIDToTypeID( "#Ang" );

  var desc1 = new ActionDescriptor();

  var desc2 = new ActionDescriptor();

  var ref1 = new ActionReference();

  ref1.putEnumerated( idBrush, idOrdinal, idTarget );

  desc1.putReference( idNull, ref1 );

  desc2.putUnitDouble( idBrushAngles, idAngle, deg );

  desc1.putObject( idWhat, idBrush, desc2 );

  executeAction( idSet, desc1, DialogModes.NO );

}

It is basically the one that I have working with brush size but this time replacing the new variable plus changing the units to angle instead of pixels.

Any feedback welcome!

Thanks,

Pol

I think Mike Hale posted this code a while back, but it only applies to default round brush-tips, not sampled ones, erodible etc.

#target photoshop
	
function setBrushFeatures(Diameter, Hardness, Angle, Roundness, Spacing, Flipy, Flipx) {
	var ref = new ActionReference();
	ref.putEnumerated(charIDToTypeID("capp"), charIDToTypeID("Ordn"), charIDToTypeID("Trgt"));
	var appDesc = executeActionGet(ref);
	var toolDesc = appDesc.getObjectValue(stringIDToTypeID('currentToolOptions'));
	var brushDesc = toolDesc.getObjectValue(stringIDToTypeID('brush'));
	if (brushDesc.hasKey(stringIDToTypeID('sampledData'))) {
		var SampleData = brushDesc.getString(stringIDToTypeID('sampledData'));
		var Name = brushDesc.getString(stringIDToTypeID('name'))
		Hardness = undefined;
	}else{
		if (Hardness == undefined) Hardness = brushDesc.getDouble(stringIDToTypeID('hardness'));
	}

	if (Diameter == undefined) Diameter = brushDesc.getDouble(stringIDToTypeID('diameter'));
	if (Angle == undefined) Angle = brushDesc.getDouble(stringIDToTypeID('angle'));
	if (Roundness == undefined) Roundness = brushDesc.getDouble(stringIDToTypeID('roundness'));
	if (Spacing == undefined) Spacing = brushDesc.getDouble(stringIDToTypeID('spacing'));
	if (Flipy == undefined) Flipy = brushDesc.getBoolean(stringIDToTypeID('flipY'));
	if (Flipx == undefined) Flipx = brushDesc.getBoolean(stringIDToTypeID('flipX'));

	var SampleIntr = brushDesc.getBoolean(charIDToTypeID('Intr'));
	var desc = new ActionDescriptor();
	var ref = new ActionReference();
	ref.putEnumerated(charIDToTypeID("Brsh"), charIDToTypeID("Ordn"), charIDToTypeID("Trgt"));
	desc.putReference(charIDToTypeID("null"), ref);
	var desc1 = new ActionDescriptor();
	desc1.putDouble(stringIDToTypeID('diameter'), Diameter);

	if (Hardness != undefined) desc1.putDouble(stringIDToTypeID('hardness'), Hardness);
	desc1.putDouble(stringIDToTypeID('angle'), Angle);
	desc1.putDouble(stringIDToTypeID('roundness'), Roundness);
	desc1.putDouble(stringIDToTypeID('spacing'), Spacing);
	desc1.putBoolean(stringIDToTypeID('flipY'), Flipy);
	desc1.putBoolean(stringIDToTypeID('flipX'), Flipx);

	if (brushDesc.hasKey(stringIDToTypeID('sampledData'))) {
		desc1.putString(stringIDToTypeID('sampledData'), SampleData);
		desc1.putString(stringIDToTypeID('name'), Name);
		desc1.putBoolean(charIDToTypeID('Intr'), SampleIntr);
	}

	var desc5 = new ActionDescriptor();
	var idnull = charIDToTypeID("null");
	var ref3 = new ActionReference();
	var idBrsh = charIDToTypeID("Brsh");
	var idOrdn = charIDToTypeID("Ordn");
	var idTrgt = charIDToTypeID("Trgt");
	ref3.putEnumerated(idBrsh, idOrdn, idTrgt);
	desc5.putReference(idnull, ref3);

	var idsampledBrush = stringIDToTypeID("sampledBrush");
	desc5.putObject(charIDToTypeID("T   "), idsampledBrush, desc1);
	executeAction(charIDToTypeID("setd"), desc5, DialogModes.NO);
}

setBrushFeatures(undefined, undefined, 45, undefined, undefined, undefined)

Thanks, c.pfaffenbichler!!

I got it to work with the code you suggested from Mike Hale. One little detail, in line 52 there is a missing space in the "T  " command, should be "T   ".

I cleaned up the code an label it for others who might be interested:

function setBrushFeatures(Diameter, Hardness, Angle, Roundness, Spacing, Flipy, Flipx) {
	// get app object
	var appAR = new ActionReference();
	appAR.putEnumerated(charIDToTypeID("capp"), charIDToTypeID("Ordn"), charIDToTypeID("Trgt"));
	var app = executeActionGet(appAR);

	// get brush settings
	var brush = app.getObjectValue(stringIDToTypeID('currentToolOptions')).getObjectValue(stringIDToTypeID('brush'));

	// set defaults if undefined (copies current brush values)
	if (brush.hasKey(stringIDToTypeID('sampledData'))) {
		var SampleIntr = brush.getBoolean(charIDToTypeID('Intr'));
		var SampleData = brush.getString(stringIDToTypeID('sampledData'));
		var Name = brush.getString(stringIDToTypeID('name'))
		Hardness = undefined;
	} else if(Hardness == undefined) Hardness = brush.getDouble(stringIDToTypeID('hardness'));

	if (Diameter == undefined) Diameter = brush.getDouble(stringIDToTypeID('diameter'));
	if (Angle == undefined) Angle = brush.getDouble(stringIDToTypeID('angle'));
	if (Roundness == undefined) Roundness = brush.getDouble(stringIDToTypeID('roundness'));
	if (Spacing == undefined) Spacing = brush.getDouble(stringIDToTypeID('spacing'));
	if (Flipy == undefined) Flipy = brush.getBoolean(stringIDToTypeID('flipY'));
	if (Flipx == undefined) Flipx = brush.getBoolean(stringIDToTypeID('flipX'));

	// action with the new parameters
	var paramsAD = new ActionDescriptor();
	paramsAD.putDouble(stringIDToTypeID('diameter'), Diameter);

	if (Hardness != undefined) paramsAD.putDouble(stringIDToTypeID('hardness'), Hardness);
	paramsAD.putDouble(stringIDToTypeID('angle'), Angle);
	paramsAD.putDouble(stringIDToTypeID('roundness'), Roundness);
	paramsAD.putDouble(stringIDToTypeID('spacing'), Spacing);
	paramsAD.putBoolean(stringIDToTypeID('flipY'), Flipy);
	paramsAD.putBoolean(stringIDToTypeID('flipX'), Flipx);

	if (brush.hasKey(stringIDToTypeID('sampledData'))) {
		paramsAD.putString(stringIDToTypeID('sampledData'), SampleData);
		paramsAD.putString(stringIDToTypeID('name'), Name);
		paramsAD.putBoolean(charIDToTypeID('Intr'), SampleIntr);
	}

	// action to modify brush
	var brushAD = new ActionDescriptor();
	var brushAR = new ActionReference();
	brushAR.putEnumerated(charIDToTypeID("Brsh"), charIDToTypeID("Ordn"), charIDToTypeID("Trgt"));
	brushAD.putReference(charIDToTypeID("null"), brushAR);

	// execute action to modify brush with the new parameters
	brushAD.putObject(charIDToTypeID("T   "), stringIDToTypeID("sampledBrush"), paramsAD);
	executeAction(charIDToTypeID("setd"), brushAD, DialogModes.NO);
}

Thanks so much again!

One little detail, in line 52 there is a missing space in the "T  " command, should be "T   ".

Sorry, I have had problems like this before but had forgotten to check if the code had pasted intact.

[Kukurykus]

I corrected both codes.

[cmext73998110]

Great code!

But the maximum value I can use for the spacing parameter is 1000. What should I do to use a value greater than 1000?

Is it possible?

Thanks!

[c.pfaffenbichler]

In the Brush Settings Panel 1000% is the maximum.
