Advanced Image Editing

Figures and tables are common numbered environments in Liii STEM's Text Mode. For methods of insertion and referencing, see Referencing Numbered Content. This guide will help you master all operations related to images.

1 Distinguishing Between Figure and Image

In English context, Figure is often used to refer to diagrams, illustrations, or charts in papers and professional manuals. Image generally refers to ordinary pictures. Liii STEM adopts the original meanings of both words: Figure (numbered environment) is an Image with a caption; while Image (not numbered) is just a single picture without a caption. Based on the above concepts, you can distinguish between the following two operations.

1.1 Inserting Figure

General image insertion defaults to "Insert Figure", which means an image with a caption. After inserting a Figure, you need to place your required image inside the Figure environment by pasting or inserting an Image.

1.2 Inserting Image

Special image insertion, only "Insert Image", which means a single independent picture.

2 Two Methods of Inserting Images

2.1 Embedding Image

This method embeds the image itself into the document, similar to inserting images in Word documents.

• In the Mode Toolbar, sequentially click Insert -> Image -> Insert Image.

2.2 Linking Image

This method only inserts a link to the image, similar to inserting images in $\LaTeX$.

Advantages of using links: smaller document size, multiple documents can share the same image, and images can be updated independently of the document. Disadvantages: the document is no longer self-contained; if you send the document to others, you need to additionally send all linked images separately.

• In the Mode Toolbar, sequentially click Insert -> Image -> Link Image.
• You can click the ↑ style button on the Environment Toolbar to directly embed the image into the document, changing to the first image-text integrated insertion method.

3 Adjusting Image Properties

By default, images are displayed at their original size in Liii STEM. You can set different widths, heights, and positions for images in the Environment Toolbar.

3.1 Adjusting Size

• If you only set the width or only set the height, the image will scale proportionally.

For example, entering a width of 1 par will make the image occupy an entire paragraph width and automatically adjust the height. For regular images, we recommend setting the width to 0.5par.

• You can use w and h as special lengths for the image's default width and height.

For example, specifying width as 2w and height as 2h will display the image at twice the default size.

3.2 Adjusting Position

• Use - to indicate left or downward movement; enter value % to indicate movement distance.

For example, setting x offset to 50% will center the image.

Note: Setting y position only takes effect in Figure environments. Single Images cannot use vertical movement. And Big Figure environments automatically center images.
