Exif Information on picture

Sweet, I keep meaning to ask you how to create a layer.
I put a note in the Layers doc page linking here.

It took a while before I figured out that I had to create a button like you explained before on the page about layers. But now the script looks like this and it does what I wanted it to do. Thanks for the help.

// shows Exif information
if (Document.EXIF != null && Document.EXIF.Exists)
{
 var expt = Document.EXIF.GetValueByName("ExposureTime");
 var fnum = Document.EXIF.GetValueByName("FNumber");
 var isos = Document.EXIF.GetValueByName("ISOSpeedRatings");
 var expp = Document.EXIF.GetValueByName("ExposureProgram");
 var dtor = Document.EXIF.GetValueByName("DateTimeOriginal");

 var li = Document.LayeredImage;
 var wiz = Application.CreateWizard("35AFBDB5-1B26-4195-8786-83C8E1CBC08E");
 wiz.SizeX = li.sizeX;
 wiz.SizeY = li.sizeY;
 li.CreateLayer(-1, wiz, "35AFBDB5-1B26-4195-8786-83C8E1CBC08E");
 var newlayer = li.GetLayer(0);
 DrawTool.SetColor1(100, 100, 100, 100);
 DrawTool.RECTANGLE(newlayer, 0, 405, 210, 320, 126);
 DrawTool.SetColor1(0, 0, 0, 100);
 DrawTool.TEXT(newlayer, "Arial", 40, 100, 100, "Exposure Time ");
 DrawTool.TEXT(newlayer, "Arial", 40, 400, 100, expt);
 DrawTool.TEXT(newlayer, "Arial", 40, 100, 145, "F-Number      ");
 DrawTool.TEXT(newlayer, "Arial", 40, 400, 145, fnum);
 DrawTool.TEXT(newlayer, "Arial", 40, 100, 190, "ISO Value     ");
 DrawTool.TEXT(newlayer, "Arial", 40, 400, 190, isos);
 DrawTool.TEXT(newlayer, "Arial", 40, 100, 235, "Mode          ");
 DrawTool.TEXT(newlayer, "Arial", 40, 400, 235, expp);
 DrawTool.TEXT(newlayer, "Arial", 40, 100, 280, "Date & Time   ");
 DrawTool.TEXT(newlayer, "Arial", 40, 400, 280, dtor);
}

So the next things I need are:

A command to show both layers, while the new layer is the active one.
A way to keep my new button, the next time I start the programm.

I've seen the SDK, bit out of my league there...

The button should be remembered automatically. But there is a small catch - if you have multiple windows open simultaneously, the last one closed will overwrite the global configuration. So, just make sure that when you are adding the button, you only have one window open and close it (or just the image) after adding the button and it will be there next time you start the program.

Also, since you figured out how to work with the configuration and removed the "Document - Extract Document Part" step, you may also want to get rid of the "Display Configuration" step. That way, you won't have to click on OK each time.

I am not entirely sure what you mean by the first thing ("show both layers"). The new layer should be visible by default. Do you mean you want to select the added layer in the list of layers? If so, try this:

li.PutIndicesToState(Context, "LAYER", 0);

The end of the script is probably the best place. If you want to select both layers, this should do it:

li.PutIndicesToState(Context, "LAYER", [0, 1]);

Thanks, both tips worked. Both layers were indeed visible, but I wanted the new layer to be the active one, so I could move it without selecting it first. Otherwise you'd always end up moving the image itself by accident.

I did have multiple windows open yesterday, so that probably caused my button to disappear all the time. I won't make that mistake again.

I will be modifying the new tool in the next few days. I also want to mention this program and the tool to some other photo enthusiasts. But I doubt they will want to enter the script themselves (I can send them a text file and a manual, but still). How can I make the new button portable? And is there a way to make a new icon for it?

Glad to hear that.

There currently is no way to add a custom icon (except writing a plug-in) - you can only select one of the built-in ones for your button. Maybe in future version.

You can export your button - while you are in the configuration, you need to get to the "Command List" step, where it shows the list of buttons. There is a save icon above the list that saves the currently selected one into a .rwcommands file. This file can then be dragged and dropped onto this toolbar to add it back.

The video demonstrating how to reconfigure the toolbar is finally up - here. You have already figured it out, but it may be useful for other people.

I have also re-formatted the code and added {}, which probably somehow got lost.

Thanks. Having no experience with JavaScript, I'm not surprised I missed something. But luckily the procedure worked fine without.

I have changed the code a bit to show more data:

//Show Exif information
if (Document.EXIF != null && Document.EXIF.Exists)
{
 var expt = Document.EXIF.GetValueByName("ExposureTime");
 var fnum = Document.EXIF.GetValueByName("FNumber");
 var isos = Document.EXIF.GetValueByName("ISOSpeedRatings");
 var expp = Document.EXIF.GetValueByName("ExposureProgram");
 var dtor = Document.EXIF.GetValueByName("DateTimeOriginal");
 var modl = Document.EXIF.GetValueByName("Model");
 var exbv = Document.EXIF.GetValueByName("ExposureBiasValue");
 var focl = Document.EXIF.GetValueByName("FocalLength");
 var comp = Document.EXIF.GetValueByName("Compression").substring(0,4);
 var fla1 = Document.EXIF.GetValueByName("Flash");
 var fla2 = fla1.indexOf("fired");
 if (fla2 = -1) {var flsh = "no";}
 else {var flsh = "yes";}
 var li = Document.LayeredImage;
 var wiz = Application.CreateWizard("35AFBDB5-1B26-4195-8786-83C8E1CBC08E");
 wiz.SizeX = li.sizeX;
 wiz.SizeY = li.sizeY;
 li.CreateLayer(-1, wiz, "35AFBDB5-1B26-4195-8786-83C8E1CBC08E");
 var newlayer = li.GetLayer(0);
 DrawTool.SetColor1(100, 100, 100, 100);
 DrawTool.RECTANGLE(newlayer, 0, 380, 260, 300, 175);
 DrawTool.SetColor1(0, 0, 0, 100);
 DrawTool.TEXT(newlayer, "Arial", "BOLD", 40, 90, 88, "Date & Time");
 DrawTool.TEXT(newlayer, "Arial", "BOLD", 40, 345, 88, dtor);
 DrawTool.TEXT(newlayer, "Arial", "BOLD", 40, 90, 122, "Model");
 DrawTool.TEXT(newlayer, "Arial", "BOLD", 40, 345, 122, modl);
 DrawTool.TEXT(newlayer, "Arial", "BOLD", 40, 90, 156, "Mode");
 DrawTool.TEXT(newlayer, "Arial", "BOLD", 40, 345, 156, expp);
 DrawTool.TEXT(newlayer, "Arial", "BOLD", 40, 90, 190, "Compresssion");
 DrawTool.TEXT(newlayer, "Arial", "BOLD", 40, 345, 190, comp);
 DrawTool.TEXT(newlayer, "Arial", "BOLD", 40, 90, 224, "Focal Length");
 DrawTool.TEXT(newlayer, "Arial", "BOLD", 40, 345, 224, focl);
 DrawTool.TEXT(newlayer, "Arial", "BOLD", 40, 90, 258, "Exposure Time");
 DrawTool.TEXT(newlayer, "Arial", "BOLD", 40, 345, 258, expt);
 DrawTool.TEXT(newlayer, "Arial", "BOLD", 40, 90, 292, "ISO Value");
 DrawTool.TEXT(newlayer, "Arial", "BOLD", 40, 345, 292, isos);
 DrawTool.TEXT(newlayer, "Arial", "BOLD", 40, 90, 326, "F-Number");
 DrawTool.TEXT(newlayer, "Arial", "BOLD", 40, 345, 326, fnum);
 DrawTool.TEXT(newlayer, "Arial", "BOLD", 40, 90, 360, "Exposure Bias");
 DrawTool.TEXT(newlayer, "Arial", "BOLD", 40, 345, 360, exbv);
 DrawTool.TEXT(newlayer, "Arial", "BOLD", 40, 90, 394, "Flash");
 DrawTool.TEXT(newlayer, "Arial", "BOLD", 40, 345, 394, flsh);
 li.PutIndicesToState(Context, "LAYER", 0);
}

I don't think this editor is really suitable for this kind of thing. 😊

You need to indent all the lines with code with a space.

Theres a bookmarklet you can use to make it less painful, just drag that to your bookmarks, select all your code in the post then click that bookmark to have it all indented.
