| | Region operations |
| | A Region is simply an area, as the name implies, and is implemented as a "y-x-banded" array of rectangles. To explain: Each Region is made up of a certain number of rectangles sorted by y coordinate first, and then by x coordinate.
|
| |
| | General DC operations |
| | DC means Device Context, just like Graphics Context (GC) of X Lib. DC represents a rectangle area on the actual screen or a virtual screen created in memory. We call the rectangle area as "surface" of the DC.

| | DC attribute operations |
| |
| | Palette operations |
| |
| | General drawing functions |
| |
| | Mapping Operations |
| | The mapping mode defines the unit of measure used to transform page-space units into device-space units, and also defines the orientation of the device's x and y axes.
|
| |
| | Clipping operations |
| |
| | BITMAP and blitting operations |
| | Example:
|
| |
| | Icon operations |
| |
| | Rectangle operations |
| |
| | Logical font operations |
| | MiniGUI uses logical font to render text in a DC. You can create a logical font by using CreateLogFont and select it into a DC by using SelectFont, then you can use this logical font to render text by using TextOutLen or DrawTextEx.
|
| |
| | System charset and font operations |
| | MiniGUI creates a few system fonts to draw menu text, window caption, or other general items. MiniGUI at least creates two system fonts: one mono-space logical font for single-byte charset, and one mono-space logical font for multi-byte charset. For the multi-byte charset, the width of one multi-byte character should be equal to the width of two single-byte characters.
|
| |
| | Text parsing functions |
| | MiniGUI uses logical font to output text, also uses logical font to parsing the multi-byte characters and words in the text.
|
| |
| | BIDI types |
| | Values for BIDI types.
|
| |
| | Operators for Unicode character and string |
| |
| | Text output functions |
| |
| | Bitmap structure |
| | MiniGUI uses a MYBITMAP structure to represent a device-independent bitmap, and BITMAP structure to represent a device-dependent bitmap.
|
| |
| | Bitmap file load/save operations |
| | Example:
|
| |
| | Rendering Text in Complex/Mixed Scripts |
| | To lay out, shape, and render a text in mixed scripts, you should call GetUCharsUntilParagraphBoundary function first to convert a multi-byte string to a Unicode string under the specified white space rule, breaking rule, and transformation rule. For example, converting a general C string in UTF-8 or GB18030 to a Uchar32 string by calling this function. You can call CreateLogFontForMChar2UChar function to create a dummy logfont object for this purpose in order to expense a minimal memory.

| |
| | Functions for Linux DRM integration |
| | These functions can be used to get the DRM device file descriptor and the information of the hardware surface corresponding to the DC which is created by the Linux DRM engine. By using the information, we can integrate MiniGUI with other graphics libraries, such as Cairo (vector graphics) and Mesa (3D graphics).
