# Tabs

Although there are many other uses, Hugin is primarily a tool for assembling multiple photos and creating a "seamless" panorama.

Hugin is a program that is "tab" based. Below you see a partial example screen of Hugin showing the tabs.

This process of assembling multiple photos and creating a "seamless" panorama is completely automatic if you use the Hugin Assistant tab, which is the default tab, but Hugin also allows full manual control of every stage. For this, Hugin provides three user interface options: Simple, Advanced and Expert. The Hugin simple mode consists of the Hugin Assistant tab and a few other tabs (as displayed above) that give you simple but effective control on what you are doing.

This is a quick overview of this tab system for the Simple interface. It isn't a step by step tutorial. You can find these tutorials on the Hugin website.

For this same overview regarding the "old" user interface (but still the user interface of the current stable release), you can start with Hugin Main window old gui[*].

## Assistant

The Hugin Assistant tab is the fully automatic part of Hugin; here you can load images, align them and stitch them into a panorama without having to use any of the other tabs. The Hugin Assistant tab also consists of a panoramic overview and a preview. This overview and preview are visible on the other tabs as well, be it with different functionality and sometimes slightly modified layout.

Alternatively, you can use this Assistant as the first step in creating a project that can involve the use of some or all of the other tabs. You can also switch to one of the other user interface modes, Advanced and Expert, if you want or need to.

## Preview

In the Hugin Preview tab, you have options to check your images and positions, the white balance, control points (equal points in two overlapping images), etcetera. Changes will immediately be displayed in this preview. This Hugin Preview tab is the same preview as displayed in the Hugin Assistant tab and all other tabs in the Simple User Interface.

## Layout

The Layout tab shows the entire project as a diagram with colour-coded lines connecting each of the photographs.

Screenshot of Layout tab; click for larger versions

Green lines connecting images show the control points have a small error; red lines show a large error. Grey lines show no control points connecting the images.

You can see where the project is OK and where there are problems if it isn't quite right. Just click on any connection and Hugin jumps to the Control Points tab to edit that pair of photos.

Use the Scale slider to change the size of the photo thumbnails. This only affects the Layout display and won't change the final panorama.

## Projection

The Hugin Projection tab is for adjusting the projection of the panorama; some projections have adjustable parameters that will appear when selected.

## Move/Drag

The Hugin Move/Drag tab is used to recentre the panorama interactively (or place it for whatever reason off centre).

## Crop

The Hugin Crop tab displays a rectangle over your preview. By dragging the edges of this rectangle, you can adjust the output area of the panorama.
