Windows program design Reading Notes-text and font

I. font type:

1. GDI font. Stored in hard disk files.

1.1 dot matrix font. It is also called a bitmap font. It is stored in the form of Bitmap pixels. Do not scale at will. The advantage is fast display and good readability. Each dot matrix font cannot exceed 6 types.

Example: system, fixedsys, terminal, courier, MS Serif, MS sans serif, small fonts

1.2 strokes. The advantage is random scaling, slow display, and poor readability of small fonts. Suitable for plotter.

Example: Modern, Roman, script

1.3 TrueType font, which can be infinitely scaled and used for video display and printer.

Example: Courier New..., Times New Roman..., Arial..., symol

2. device font. Inherent in the output device.

2. character output functions.

Settextcolor

Setbkmode

Setbkcolor

Get the system color set by the user. getsyscolor (color_window ...)

CDC: settextcharacterextra // Character Spacing

SelectObject (HDC, getstockobject (system_font ))

Some functions:

Createfont or createfontindirect // create a font

Gettextface // get the font name

　　Bool gettextmetrics (HDCHDC,LptextmetricLptm );// Obtain the current font information

　　Bool gettextextentpoint32 (HDCHDC,LpctstrLpstring,IntCbstring,LpsizeLpsize ); // Obtain the string size.

Settextjustification (HDC, PRC-> right-PRC-> left-size. CX, cspacechars); // used for the two segments. The following cspacechars space must be evenly divided (PrC-> right-PRC-> left-size. (CX) space. After a row ends, use settextjustification (HDC, 0, 0) to eliminate the uplink errors.

Three, logfont structure, member Description: http://baike.baidu.com/view/2421591.html? Fromtaglist

You can use logfont to set many font information. Including font rotation. For example, LF. lforientation = 300; converts to 30 degrees.

GetObject (hfont, sizeof (logfont), & lf); // get logfont

Hfont = createfontindirect (& lf); // set logfont
