In the process of processing a digital image, it is required not only to perform a complete flattening of layers, that is, transform them into one image, but also to glue two or more layers together for further work in a multi-layer mode. Adobe Photoshop, Corel PhotoPaint, Gimp, and other raster graphics programs support this technology. As an example, the procedure of merging two layers in Gimp, smoothly transitioning from one to another, is considered.
Necessary
Free Gimp software installed on your computer
Instructions
Step 1
Create a layered image in the Gimp. To do this, open the picture through the "File", "Open" menu. Find the file on your computer and click the "Open" button in the dialog box. Repeat the procedure for the second picture. Let the first drawing be the base.
Step 2
In the edit window for the second image, select Copy Visible from the Edit menu. Go to editing the canvas and choose "Edit" - "Paste As" - "New Layer". The name of the newly inserted layer will appear in the layers window on the right side of the screen. Move between layers by right-clicking on the name of the one that needs to be activated. Close the second picture that is no longer needed without saving.
Step 3
Activate the top layer and switch to quick mask mode. To do this, click on the dotted box located in the lower left corner above the status bar. The image will be covered with a red "Film".
Step 4
Set the background color to black and the foreground color to white by clicking on the small squares next to the color indicator. Select the Gradient tool from the panel. Set to normal mode. Set the shape of the gradient, for example, radial. Click on the field opposite the word "Gradient" to open the list of types and select "Main to Transparent". Adjust the rest of the parameters depending on your needs, checking the result of their action.
Step 5
Build a gradient from the center of the image to the edge. To do this, position the cursor in the middle, press the right mouse button and, without releasing it, extend the line to the edge of the window. The central part of the picture will be colored, the edge will remain reddish. Disable the quick mask mode by clicking its icon again. A circular selection will remain.
Step 6
Select "Invert" from the "Selection" menu. Click the Delete button. The outside of the top layer will be removed, revealing the base.
Step 7
Glue the two layers together as follows. From the Layer menu, choose Merge With Previous. The blend picture is now a single layer. Remove selection: "Selection" - "Deselect".
Step 8
To save the results of your work, click "Save As" in the "File" menu. Specify the name, type of the saved file and its location. Click "Save". For compressed.jpg"
