"Style" Tab

"Style" Tab: Used to set the uniform font style for text objects in the current uniform label thematic map. In particular, the uniform style supports setting the font type, size, rotation angle, and font color of labels by selecting a property field, enabling custom label settings to meet different label display requirements.

Font: Used to set the font for label text in a label thematic map. The combo box dropdown list on the right side of this control provides a rich selection of fonts for users to choose from. It supports adding "@" before the font name in the combo box to achieve vertical display effects. A "Recent Font" group is also provided for easy selection of recently used font names. The system supports quick keyboard navigation to fonts by their first letter. For example, pressing the letter "T" on the keyboard will display fonts starting with "T" in the dropdown list. Click the combo box dropdown list on the right side of this control and select a font. The default font is Microsoft YaHei.

When Start Expression is checked, the font will be set by selecting a property field. The font will be displayed according to the set attribute values, achieving a custom label effect with different label fonts within the same thematic map.
