Save to exr format with jsx script

[Louise2504533747tw]

Hi, 

Is there a way to save a document as Exr with a jsx script ? 

My source image is a dng. With the UI, I need to change the Image >  Mode to 32 bits/Channels

Once I've set the 32 bits/Channels, I have the OpenEXR option in save as type.

I'd like to be able to do that in a jsx script.

Regards,

Louise

@Louise2504533747tw – Do you know how to script? Why a script over an action?

Some context on how the script would be used would help.

Here is an example, not knowing the context/details it may or may not suit your requirements:

#target photoshop

activeDocument.bitsPerChannel = BitsPerChannelType.THIRTYTWO;

var docName = activeDocument.name.replace(/\.[^\.]+$/, '');

try {
	var savePath = activeDocument.path;
} catch (e) {
	var savePath = Folder.selectDialog('The doc has never been saved, please select the save folder:');
}

var saveFileEXR = new File(savePath + '/' + docName + ".exr");

if (saveFileEXR.exists) {
	// true = 'No' as default active button
	if (!confirm("File exists, overwrite: Yes or No?", true))
		// throw alert("Script cancelled!");
		throw null;
}

saveEXR(0, 1, saveFileEXR, false, true);

function saveEXR(compression, alphaChannelOptions, savePath, asCopy, lowerCase) {
	// Compression: 0 = None | 1 = RLE | 2 = Zlib | 4 = Wavelet | 5 = PIXR24 on 32 bit
	function c2t(s) {
		return app.charIDToTypeID(s);
	}
	var s2t = function (s) {
		return app.stringIDToTypeID(s);
	};
	var descriptor = new ActionDescriptor();
	var descriptor2 = new ActionDescriptor();
	descriptor2.putInteger( s2t( "bitDepth" ), 32 );
	descriptor2.putInteger( s2t("compression"), compression );
	descriptor2.putInteger( s2t( "alphaChannelOptions" ), alphaChannelOptions );
	descriptor.putObject( s2t( "as" ), c2t( "EXRf" ), descriptor2 );
	descriptor.putPath( s2t( "in" ), savePath );
	descriptor.putBoolean( s2t( "copy" ), asCopy );
	descriptor.putBoolean( s2t( "lowerCase" ), lowerCase );
	descriptor.putEnumerated( s2t( "saveStage" ), s2t( "saveStageType" ), s2t( "saveSucceeded" ));
	executeAction( s2t( "save" ), descriptor, DialogModes.NO );
}

Hi Stephen,

It's exactly what I needed.

I can export all dng images to exr from a source folder with a command line.

And Yes I know how to script but mainly in python and I don't know photoshop api.

Thanks a lot,

Louise
