Watermark Action

[benjamink78098692]

Hi! I am in Photoshop now and would like to make an action for placing watermarks so that they take up 10% of the width of the image and are placed so that they are 3% in from the left and 3% from the bottom on the canvas. How do I do this?

To be that precise you'd need a custom script. See Photoshop Scripting for help with scripting.

If you want to watermark with an Action, you absolutely can. This is a tutorial shows how I watermark my own images for web use. Maybe this method will work for you.

There's a free version, and if you want more controls, there's a paid version at pixelsucht.com

You could create a watermark PNG file.  Then place in onto you images with a Photoshop scripts that would size it relative to the document width and locate it where you want it located.  I have posted a script the does something like you want.  It would be easy to modify for your requirements. My script resizes relative to the documents height.  I think for the general case the make more sense than the documents width. If the aspect ratio of your logo is wide resizing it to 10% of the document width  the height of your logo would be very small on portrait images. Create you logo PNG file large images downsize better than they enlarge

#target photoshop;  
app.bringToFront();  
var logoFile = "~/Desktop/JJMack.png"; // Watermark file should be large for resize down works better than up
var LogoSize = 10; // percent of document height to resize Watermark to
var LogoMargin = 1;                                         // percent of Document height the Watermark should have as a margin
placeWatermark(logoFile, LogoSize, LogoMargin);             // Place Watermark  into the bottom right of document
function placeWatermark(Image,Size,Margin){  
  if(!documents.length) return;   // if no document return
  try{  
  var doc = app.activeDocument; // set Doc object to active document
  app.displayDialogs = DialogModes.NO; // Dialog off 
  var strtRulerUnits = app.preferences.rulerUnits; // Save Users ruler units 
  var strtTypeUnits = app.preferences.typeUnits; // Save Users Type units 
  app.preferences.rulerUnits = Units.PIXELS; // work with pixels 
  app.preferences.typeUnits = TypeUnits.PIXELS; // work with pixels 
  var fileObj = new File(Image);                 // the passed file
  if(!fileObj.exists){   // If file does not exits tell user 
  alert(fileObj.name  + " does not exist!");  
  return;  
  }  
  placeFile(fileObj); // Place in file the Watermark png file
  activeDocument.activeLayer.resize(100 ,100,AnchorPosition.MIDDLECENTER); // Insure Place did not scale layer  
  var SB = activeDocument.activeLayer.bounds; // get layers bounds 
  var layerHeight = SB[3] - SB[1]; // get layers height  
  var resizePercent = (100/layerHeight)*(Size/100*doc.height.value); // Percent to resize by 
  activeDocument.activeLayer.resize(resizePercent ,resizePercent,AnchorPosition.MIDDLECENTER);  // Resize width and height by percentage 
  SB = activeDocument.activeLayer.bounds; // get resized layers bounds  
  activeDocument.activeLayer.translate(-SB[0].value,-SB[1].value); // Move resized layer to top left canvas corner 
  var LayerWidth = (SB[2].value - SB[0].value);  
  var LayerHeight = (SB[3].value - SB[1].value);  
  marginSize = Margin/100*doc.height.value; // move resized watermark into the document lower right corner with some margin
  activeDocument.activeLayer.translate((doc.width.value -marginSize - LayerWidth),( doc.height.value -marginSize - LayerHeight));
  }
  catch(e) { alert(e + ': on line ' + e.line); } // inform user of error  
  finally{  
  app.preferences.rulerUnits = strtRulerUnits; // Restore user ruler units  
  app.preferences.typeUnits = strtTypeUnits; // Restore user type units
