GIMP is an open source cross-platform image editor that is similar to Adobe Photoshop. The learning curve for GIMP is pretty steep so this post aims to describe how to edit layers of a PSD file. In this example, we assume that we want to add our own image to a mock-up similar to what is shown here.
The steps to follow are:
- Open the .psd file using GIMP. A dialog toolbox for “Layers-Brushes” will appear. Select the layers tab click on the layer you want to edit.
- Open the image file, that you want to replace the layer with, using GIMP. At this point GIMP is open twice. Select the replacement image in GIMP and click Ctrl+C to copy it.
- Return to the GIMP window where the .psd file is open and select the layer to edit. Then paste using Ctrl+V. A new layer called “Floating Selection (Pasted Layer) “should appear. Right click on it and select Scale Layer in the dropdown menu.
- A new dialog toolbox labeled “Scale Layer” appears. Adjust the numbers for the length and width to the desired levels (unfortunately there is no click and drag function for this).
- To save the final output, select File Save As and this will save the final output as a .xcf file which will allow you to edit the layers again at a later stage. You can also export the layers to a more convenient format like Jpeg.
