Typedef Documentation

gl_int_t

typedef int16_t gl_int_t

16-bit integer is used for gl_int_t

gl_uint_t

typedef uint16_t gl_uint_t

16-bit unsigned integer is used for gl_uint_t

gl_long_int_t

typedef int32_t gl_long_int_t

32-bit integer is used for gl_long_int_t

gl_long_uint_t

typedef uint32_t gl_long_uint_t

32-bit unsigned integer is used for gl_long_uint_t

gl_angle_t

typedef uint16_t gl_angle_t

The angle for the arc. Value should be positive. Value between 0 and 360 is expected, but if it happens to be bigger, it will be calculated like:

void f (gl_angle_t value) {
gl_angle_t angle = value % 360 
}

gl_coord_t

typedef int16_t gl_coord_t

The coordinates on display are linked to its pixels. To target area 50 pixels away from top and 70 pixels away from left display's edge use coordinates: \( x = 70 \) and \( y = 50 \) .

gl_fill_t

typedef void(* gl_fill_t) (gl_rectangle_t *rect, gl_color_t color)

Function used for drawing on display. Should be defined in driver.

gl_begin_frame_t

typedef void(* gl_begin_frame_t) (gl_rectangle_t *rect)

Function used for drawing on display. Should be defined in driver.

gl_frame_data_t

typedef void(* gl_frame_data_t) (gl_color_t color)

Function used for drawing on display. Should be defined in driver.

gl_end_frame_t

typedef void(* gl_end_frame_t) ()

Function used for drawing on display. Should be defined in driver.

Enumeration Type Documentation

gl_brush_style_t

enum gl_brush_style_t

Enum containing styles for brush that are supported in the drawing functions. It should be used for controlling the look of shapes that uses brush in drawing.

Enumerator
GL_BRUSH_STYLE_NONE	Brush area will not be painted.
GL_BRUSH_STYLE_FILL	Brush area will be painted with one color set by gl_set_brush_color .
GL_BRUSH_STYLE_GRADIENT_TOP_DOWN	Brush area will be painted gradientally from top to bottom, with colors set by gl_set_brush_color_from for top part, and gl_set_brush_color_to for bottom part.
GL_BRUSH_STYLE_GRADIENT_LEFT_RIGHT	Brush area will be painted gradientally from left to right, with colors set by gl_set_brush_color_from for left part, and gl_set_brush_color_to for right part.

gl_image_format_t

enum gl_image_format_t

Enum containing predefined signs for image format. This format is supported in NECTO Studio's resource generator.

Enumerator
GL_IMAGE_FORMAT_BITMAP_1BPP	Image in bitmap format with 1 bpp.
GL_IMAGE_FORMAT_BITMAP_4BPP	Image in bitmap format with 4 bpp.
GL_IMAGE_FORMAT_BITMAP_8BPP	Image in bitmap format with 8 bpp.
GL_IMAGE_FORMAT_BITMAP_16BPP	Image in bitmap format with 16 bpp.
GL_IMAGE_FORMAT_JPEG	Image in jpeg format.

gl_font_orientation_t

enum gl_font_orientation_t

Enum containing options for orientation of the text. It should be used for controlling orientation of the text or single character when drawing.

Enumerator
GL_FONT_HORIZONTAL	Text is horizontal.
GL_FONT_VERTICAL	Text is vertical but characters in text are horizontal.
GL_FONT_VERTICAL_COLUMN	Both text and characters in it are vertical.
