Purpose
Specifies a text style. You can use this clause in the MapBasic window in MapInfo Pro.
Syntax
Font font_expr font_expr is a Font expression, for example:
MakeFont( fontname, style, size, fgcolor, bgcolor )Description
The Font clause specifies a text style. Font is a clause, not a complete MapBasic statement. Various object-related statements, such as the Create Text statement, allow you to specify a Font setting; this lets you choose the typeface and point size of the new text object. If you omit the Font expression from a Create Text statement, the new object uses MapInfo Pro's current Font. The keyword Font may be followed by an expression that evaluates to a Font value.
This expression can be a Font variable:
Font font_varor a call to a function (for example, CurrentFont() function or MakeFont() function) which returns a Font value:
Font MakeFont("Helvetica", 1, 12, BLACK, WHITE)With some MapBasic statements (for example, the Set Legend statement), the keyword Font can be followed immediately by the five parameters that define a Font style (font name, style, point size, foreground color, and background color) within parentheses:
Font("Helvetica", 1, 12, BLACK, WHITE)You can also directly assign a string-based style clause into a variable of type Font. For example,
dim fnt as Font
fnt = "Font (""Arial"",0,9,0)"
'this assignment will work now, and string-based font clause will convert
Font variable.The following table summarizes the components that define a font:
| Component | Description |
|---|---|
| font name | A string that identifies a font. The set of available fonts depends on the user's system and the hardware platform in use. |
| style | Integer value. Controls text attributes such as bold, italic, and underline. See table below for details. |
| size | Integer value representing a point size. A point size of twelve is one-sixth of an inch tall. |
| foreground color | Integer RGB color value, representing the color of the text. See Rnd() function. |
| background color | Integer RGB color value. If the halo style is used, this is the halo color; otherwise, this is the background fill color. To specify a transparent background style in a Font clause, omit the background color. For example: |
The following table shows how the style parameter corresponds to font styles.
| Style Value | Description of text style |
|---|---|
| 0 | Plain |
| 1 | Bold |
| 2 | Italic |
| 4 | Underline |
| 8 | Strikethrough |
| 32 | Shadow |
| 256 | Halo |
| 512 | All Caps |
| 1024 | Expanded |
To specify two or more style attributes, add the values from the left column. For example, to specify both the Bold and All Caps attributes, use a style value of 513.
