Batch resize images with different background colors

Question

My goal is to achieve the following:

Batch resize images with different background colors

I already use Photoshop to batch process and center (horizontal and vertical align) 2000 different images into square 200 x 200 tiles on a white background (the images are different in size, background color, and sometimes file-type).

I can process and batch resize the images and place them on a white 200x200 tile using the batch processor and recorded 'Actions'. With transparent .png images this looks great.

Problem: Some of the images have a colored background. If an image has a colored background a white border around the image looks quite awful.

This is how the output currently looks:

How do I dynamically resize the non transparent images of different colors and sizes to 200x200 square .jpg images? I can do it manually with the color-picker but is there another option?

As you can see it is only a problem when images have a colored background.

Answer 1

If the images are not at 1:1 aspect ratio, you could try editing the problematic ones before you do the batch processing, to make them the right aspect ratio.

So, open one of these images, change the canvas size so the aspect ratio is 1:1 (i.e, so that the width and height are exactly the same), unlock the background layer. Add a new background layer under the graphic, and fill with the same colour as the graphic's background, flatten the layers and save.

Another possibility is Content Aware Scaling, although I don't know how well it will work on a graphic as it's generally intended for photographs.

Answer 2

I was able to get the action to work on a few tests, with the constraints being:

• There must be one layer
• The layer must be unlocked
• The layer must be named "Layer 1"
• The logo must be white on colored background

NOTE: The color eye dropper sample will come from the upper left corner of the logo canvas. (Thanks @Billy Kerr -- that Tool Recording is really helpful.)
