Abstract

The invention discloses a drawing system and method for real-time updating acquired image data. The system includes: a ChartCtrl module encapsulated with a canvas function; an image acquisition module, which acquires the image data from the canvas in real-time; and an image processing module, which is used for reading and analyzing the image data. The drawing system and method for real-time updating acquired image data provided by the invention utilize the encapsulated ChartCtrl class to update and collect image data in real-time and perform data analysis in real-time.

Description

technical field [0001] The invention relates to the technical field of drawing. More specifically, it relates to a drawing system and method for updating collected image data in real time. Background technique [0002] In Windows, draw Figure 1 Generally, it is carried out in the client area of ​​the view window, using various drawing functions in the device context class CDC. MFC drawing tool classes include CGdiObject, CBitmap, CBrush, CFont, CPallette, CPen and CRgn, etc. [0003] (1) CBitmap: encapsulates a GDI bitmap and provides an interface for bitmap operations. [0004] (2) CFont: encapsulates the GDI font, which can be selected as the current font in the device context. [0005] (3) CBrush: encapsulates the GDI brush, selected as the current brush of the device context, and the brush is used to fill the interior of the graphics. [0006] (4) CPen: encapsulates the GDI brush, selected as the current brush of the device context, and the brush is used to draw the...
