Diffing Images

To diff images using P4Merge, choose File>New Merge or Diff..., browse to the two image files that you want to compare, and click OK. P4Merge displays the differences between the specified images. You can display image diffs side by side or overlaid.

To enlarge or reduce the displayed images, use the zoom sliders or choose the desired display option from the View menu.

To highlight differences, check Highlight Differences and use the adjacent slider to increase or decrease sensitivity. P4Merge highlights identical areas in gray and differences in yellow.

To blend or separate overlaid images, use the vertical slider: to blend the images equally, center the slider. To increase the amount of an image used in the composite, move the slider toward that image.

You can diff the following image file types:
