SDL3_API分类参考_显示器与窗口管理（CategoryVideo） 显示器与窗口管理（CategoryVideo） SDL 的视频子系统主要负责对底层操作系统的窗口管理进行抽象封装。你可以创建窗口、以多种方式管理窗口、将其设为全屏模式，并在窗口发生相关事件（如鼠标或键盘与窗口交互）时获取事件通知。 视频子系统还会对 OpenGL 中部分平台相关的差异进行抽象，例如：上下文创建、缓冲区交换等。这对你的应用程序可能至关重要，但你完全不必强制使用 OpenGL。事实上，SDL 也可以为这些窗口提供渲染能力：既可以使用易用的 2D API，也可以使用功能更强大的 GPU API。 当然，SDL 也可以完全不介入渲染流程，直接为你提供窗口句柄，让你自行直接使用 Vulkan、Direct3D、Metal 或其他任何你喜欢的图形 API。 视频子系统因功能需求覆盖范围很广，因此值得浏览一遍函数列表以了解可用功能。不过大多数应用只需创建窗口并监听事件即可，建议从 SDL_CreateWindow() 和 SDL_PollEvent() 开始使用。 函数 SDL_CreatePopupWindow（创建弹出窗口） SDL_CreateWindow（创建窗口）

Cairo 矢量绘图库 API 文档（中文，勇芳原创） 上下文的创建与销毁 Declare Function cairo_create(ByVal target As cairo_surface_t Ptr) As cairo_t Ptr 创建核心绘图上下文。需要一个 cairo_surface_t 作为“画布”。返回值是所有绘图操作的起点。 Declare Function cairo_reference(ByVal cr As cairo_t Ptr) As cairo_t Ptr 增加上下文引用计数。当多个部分需要共享同一个上下文时使用，防止被意外销毁。 Declare Sub cairo_destroy(ByVal cr As cairo_t Ptr) 减少引用计数并可能销毁上下文。与 create 或 reference 配对使用，管理资源释放。 Declare Function cairo_get_reference_count(ByVal cr As cairo_t Ptr) As ULong 查询当前的引用计数。主要用于调试内存管理问题。 用户数据管理 (高级功能) Declare Function cairo_get_user_data(ByVal cr As cairo_t Ptr, ByVal key As Const cairo_user_data_key_t Ptr) As Any Ptr 给上下文绑定一块自定义数据。通过唯一的 key 关联一个指针 data，并可指定一个销毁回调函数 destroy。 Declare Function cairo_set_user_data(ByVal cr As cairo_t Ptr, ByVal key As Const cairo_user_data_key_t Ptr, ByVal user_data As Any Ptr, ByVal destroy As cairo_destroy_func_t) As cairo_status_t 通过键取出之前绑定的自定义数据。 状态管理 Declare Sub cairo_save(ByVal cr As cairo_t Ptr) '保存当前所有绘图状态。将当前的颜色、线宽、变换矩阵等压入栈。 Declare

cairo_push_group_with_content(ByVal cr As cairo_t Ptr, ByVal content As cairo_content_t) 开始一个指定内容类型的绘制组。可以指定这个临时层是纯色(CAIRO_CONTENT_COLOR)、带透明度(CAIRO_CONTENT_COLOR_ALPHA)等。 Declare Function cairo_pop_group(ByVal cr As cairo_t Ptr) As cairo_pattern_t Ptr 结束临时组并返回图案。临时层被结束并包装成一个 cairo_pattern_t，可以后续用作笔刷或源。 Declare Sub cairo_pop_group_to_source(ByVal cr As cairo_t Ptr) 结束临时组并直接设为绘制源。这是最常用的流程：结束临时层，并立即将其设置为接下来绘制的“墨水”。 设置绘制源：控制“墨水”内容 Declare Sub cairo_set_source(ByVal cr As cairo_t Ptr, ByVal source As cairo_pattern_t Ptr) 设置任意图案作为绘制源。source

CAIRO_OPERATOR_ADD 相加。将颜色值相加，产生变亮效果。 “线性减淡(添加)” CAIRO_OPERATOR_MULTIPLY 正片叠底。颜色值相乘，产生变暗效果。 “正片叠底” CAIRO_OPERATOR_CLEAR 清除。将重叠区域设为完全透明。 “清除” 设置容差：控制“计算精度” Declare Sub cairo_set_tolerance(ByVal cr As cairo_t Ptr, ByVal tolerance As Double) 影响路径绘制（尤其是曲线）时的渲染精度和性能平衡。 作用：定义路径（尤其是贝塞尔曲线）被转换为像素时允许的最大误差。 值越小：曲线拟合越精确，渲染质量越高，但计算成本更高。 值越大：使用更少的线段来近似曲线，渲染速度更快，但可能不够平滑。 默认值：通常为 0.1。对于大多数屏幕显示，此值已足够。仅在需要极高精度（如大幅面打印）或极端性能优化时才需调整。 抗锯齿 Declare Sub cairo_set_antialias(ByVal cr As cairo_t Ptr, ByVal antialias As cairo_antialias_t) 枚举类型定义 Enum cairo_antialias_t

VisualFreeBasic绘画和图像编程 前言 在 Windows 图形用户界面中，屏幕上显示的所有元素——包括文字、图像、窗口、控件等——都是通过代码“绘制”出来的。VisualFreeBasic（VFB）通过封装 GDI/GDI+ 和集成 Cairo 图形库，让图形绘制变得简单直观。理解 Windows 的消息驱动机制和绘画事件，是掌握自定义图形界面的关键。 一、绘画机制概述 1.1 Windows 消息驱动机制 Windows 采用消息驱动模型，当窗口需要重绘时（如首次显示、从覆盖状态恢复、大小改变等），系统会向窗口发送 WM_PAINT 消息。开发者通过处理这些消息，在相应的事件中进行绘画操作。 1.2 绘画主体 在 VFB 中，绘画的主体可以是： 窗口：直接在窗口客户区进行绘制 控件：特定控件（如 Picture 控件）支持自定义绘制 1.3 图形库选择 yGDI：封装了 GDI 和 GDI+ 的类库，适合大多数 2D 图形操作 Cairo：跨平台的 2D 矢量图形库，支持高质量图形和透明效果 直接 GDI：使用 Windows API 直接操作设备上下文 二、窗口绘画 2.1 绘画事件 窗口提供两个主要的绘画事件： 2.1.1 FormPaintStart 事件 在系统绘制背景色之后、绘制虚拟控件之前触发，适合绘制背景或底层图形。 '[Form1]事件 : 重绘开始，刚画好背景色，还没画虚拟控件，用 gg 来画。 'hWndForm 当前窗口的句柄(WIN系统用来识别窗口的一个编号，如果多开本窗口，必须 Me.hWndForm = hWndForm 后才可以执行后续操作本窗口的代码) 'gg yGDI画画类，封装了 GDI和GDI+的 API操作类，方便绘画。 'nBackColor 窗口背景颜色（GDI颜色值，由设计时设置） '若要用Cairo绘图：Dim ca As Cairo = gg.m_Dc Function Form1_FormPaintStart(hWndForm As hWnd,gg As yGDI,nBackColor As Long) As LResult Function = FALSE ' 若不想系统继续画虚拟控件等，则应返回 TRUE 。 End Function 返回值说明 FALSE： 允许系统继续默认的绘画流程 TRUE： 停止系统绘画流程，完全由自定义代码控制 2.1.2 FormPaintEnd 事件 在所有虚拟控件绘制完成后触发，适合绘制覆盖在控件之上的图形。 '[Form1]事件 : 重绘最后，已经画好虚拟控件，用 gg 来画。 'hWndForm 当前窗口的句柄(WIN系统用来识别窗口的一个编号，如果多开本窗口，必须 Me.hWndForm = hWndForm 后才可以执行后续操作本窗口的代码) 'gg yGDI画画类，封装了 GDI和GDI+的 API操作类，方便绘画。 'nBackColor 窗口背景颜色（GDI颜色值，由设计时设置） Sub Form1_FormPaintEnd(hWndForm As hWnd,gg As yGDI,nBackColor As Long) End Sub 三、控件绘画 3.1 Picture 控件 Picture 控件是专门用于自定义绘制的控件，常用于图表、游戏、动态图形等场景。 '[Form1.Picture1]事件 : 重绘，系统通知控件需要重新绘画。 'hWndForm 当前窗口的句柄(WIN系统用来识别窗口的一个编号，如果多开本窗口，必须 Me.hWndForm = hWndForm 后才可以执行后续操作本窗口的代码) 'hWndControl 当前控件的句柄(也是窗口句柄，如果多开本窗口，必须 Me.控件名.hWndForm = hWndForm 后才可以执行后续操作本控件的代码 ) Function Form1_Picture1_WM_Paint(hWndForm As hWnd, hWndControl As hWnd) As LResult 1.使用yGDI库 Dim gg As yGDI = yGDI(hWndControl, GetSysColor(COLOR_WINDOW), True) 2.使用Cairo库 Dim ca As Cairo = cairo(hWndControl, 1) 3.直接DC Dim ps As PAINTSTRUCT Dim nDC As HDC = BeginPaint(hWndControl, @ps) '初始化并获取DC EndPaint(hWndControl, @ps) '结束绘画 Function = TRUE ' 告诉系统，我们自绘了，不需要系统绘画。 End Function 3.2 其他控件的自定义绘制 某些控件（如 Button、ListBox）也支持自定义绘制，通常通过 OwnerDraw 模式实现，这涉及更高级的编程技巧。 四、常用绘画操作 4.1 基本图形绘制（使用 yGDI） ' 绘制线段 gg.Line(x1, y1, x2, y2, [颜色], [线宽]) ' 绘制矩形 gg.Rectangle(x, y, width, height, [边框颜色], [线宽], [填充颜色]) ' 绘制椭圆/圆形 gg.Ellipse(x, y, width, height, [边框颜色], [线宽], [填充颜色]) ' 绘制圆角矩形 gg.RoundRect(x, y, width, height, 圆角X, 圆角Y, [边框颜色], [线宽], [填充颜色]) ' 绘制多边形 Dim points(5) As POINT points(0).x = 100: points(0).y = 100 points(1).x = 150: points(1).y = 50 points(2).x = 200: points(2).y = 100 points(3).x = 180: points(3).y = 150 points(4).x = 120: points(4).y = 150 gg.Polygon(@points(0), 5, RGB(0, 0, 0), 2, RGB(200, 200, 255)) ' 绘制文字 gg.TextOut(x, y, "文本内容", [颜色], [字体名], [字体大小], [格式]) gg.TextOut(10, 10, "居中对齐示例", RGB(0, 0, 0), "宋体", 12, DT_CENTER) ' 绘制图像 Dim img As yImage = yImage("image.png") gg.DrawImage(img, x, y, [宽度], [高度]) 4.2 使用 Cairo 绘制 Dim ca As Cairo = cairo(hWndControl, 1) ' 1表示不缩放 ' 设置颜色（RGBA，0-1范围） ca.SetSourceRGB(0.2, 0.4, 0.8) ' 不透明 ca.SetSourceRGBA(0.2, 0.4, 0.8, 0.5) ' 半透明 ' 绘制 ca.Rectangle(10, 10, 100, 50) ca.Fill() ' 填充 ca.Stroke() ' 描边 ' 设置线宽 ca.SetLineWidth(2.5) ' 绘制曲线 ca.MoveTo(10, 10) ca.CurveTo(50, 50, 100, 20, 150, 80) ca.Stroke() ' 绘制文字 ca.SelectFont("Arial", 12, , , , TRUE) ca.TextOut(20, 30, "Cairo 文字") 五、高级技巧 5.1 预防闪耀 WIN系统里有一个背景刷新机制，就是需要刷新控件背景，发一个消息，是否要系统为你画背景，你不处理，系统就为你画一次背景。造成闪耀。 因此，需要在自定义消息中，把 WM_ERASEBKGND 消息返回 True ，操作系统就不去绘画了，也不会产生闪耀。 Function Form1_Picture1_Custom(hWndForm As hWnd, hWndControl As hWnd, wMsg As UInteger, wParam As wParam, lParam As lParam) As LResult Select Case wMsg Case WM_ERASEBKGND Return True '防止擦除背景 End Select Function = FALSE ' 若不想系统继续处理此消息，则应返回 TRUE （俗称吃掉消息）。 End Function 5.2 局部重绘优化 对于复杂图形，只重绘需要更新的区域可以提高性能。 ' 只重绘指定区域 Dim rect As RECT rect.left = 50: rect.top = 50 rect.right = 150: rect.bottom = 150 InvalidateRect(hWndControl, @rect, TRUE) ' 在绘画事件中获取需要重绘的区域 Function WM_Paint_WithUpdateRegion(hWndForm As hWnd, hWndControl As hWnd) As LResult Dim ps As PAINTSTRUCT Dim hDC As HDC = BeginPaint(hWndControl, @ps) ' ps.rcPaint 包含了需要重绘的区域 If ps.rcPaint.right - ps.rcPaint.left > 0 Then ' 只绘制脏矩形区域内的内容 Dim gg As yGDI = yGDI(hWndControl, , True) ' ... 绘制代码 ... End If EndPaint(hWndControl, @ps) Function = TRUE End Function
