Description

画笔属性设置方法和设备 技术领域
本发明涉及电子绘图领域, 尤其涉及一种画笔属性设置方法和设备。 背景技术
现有电子绘图设备, 如果是带有触摸屏的, 使用时一般通过直接触摸屏幕的方式 来设置绘图所用的画笔属性; 如果不带有触摸屏, 则一般使用鼠标、触控板等控制光 标的设备(简称为光标控制设备),通过控制光标的方式来设置绘图设备的画笔属性。 画笔属性包括但不限于画笔的颜色、 粗细、 硬度、 透明度等。 其中, 画笔颜色又包含 多种属性, 例如, 如果使用三维的 HSL色彩空间, 即对应画笔颜色的属性包含色相、 饱和度和亮度三种属性, 则绘图时用到的画笔属性可能共有六种, 分别是色相、饱和 度、 亮度、 粗细、 硬度以及透明度。
发明人在实现本发明的过程中发现,以上两种设置电子绘图设备的画笔属性的方 法存在以下问题: 对于使用触摸屏的情况, 如果用手指触摸, 则触摸位置不够精细, 难以精确调整所需要的画笔属性; 如果使用画笔触摸, 则画笔必须从绘图区域移动到 显示画笔属性的区域, 使绘图过程受到干扰。对于使用光标控制设备的情况, 为了通 过光标调整画笔属性,就至少需要移动光标和确认操作两个步骤, 比较繁琐; 同样的, 这种方法也需要视线从当前绘图区域移动到显示画笔属性的区域,导致绘图过程受到 干扰。

参照附图, 通过下面的说明书, 本发明实施例的前述以及其它特征将变得明显。 这些实施方式只是示例性的, 不是对本发明的限制。
实施例 1
本发明实施例提供了一种电子画笔属性的设置方法, 该方法应用于安装有增量型 定位装置的电子绘图设备,这里的电子绘图设备可以是电子画板、也可以是电子画笔, 还可以是电子调色板等。
图 1是本实施例的电子画笔属性的设置方法的流程图,请参照图 1, 该方法包括: 步骤 101 : 检测所述增量型定位装置的位置变化;
步骤 102: 根据检测到的所述增量型定位装置的位置变化信息, 调整与所述增量 型定位装置绑定的画笔属性的属性值。
在本实施例中, 该增量型定位装置可以是一维定位装置, 例如旋钮、 拨盘或滚轮 等形态的旋转定位装置, 内部包含一维增量型位置传感器如旋转编码器; 也可以是二 维定位装置,例如球形的旋转定位装置或触控板形态的平面定位装置, 内部包含二维 增量型位置传感器如使用两个角位移传感器或一个平面位移传感器制成的轨迹球、使 用光学(图像)传感器或电容传感器制成的触控板等。 上述二维定位装置如被制成计 算机外设用于向计算机输入操作位置时, 也被称作计算机定点设备 (Pointing Device ) 0 当用户对安装在电子绘图设备上的定位装置进行操作时, 其位置会发生变 化, 通过步骤 101的检测, 可以确定该定位装置的位置变化。 其中, 对于该增量型定 位装置的工作原理与现有技术相同, 在此不再赘述。
由于含有旋钮、拨盘或滚轮的一维旋转定位装置和含有圆球的二维旋转定位装置 对于本实施例来说,具有触碰点不是位置检测点所以接触动作本身不会被识别为位置 变化、 圆周运动的位移范围没有物理边界、可以加入定位反馈等优点, 在使用时比较 容易避免不必要的位移,跟直线型或平面型定位装置相比, 更适宜本实施例所述的应 用。
在本实施例中, 该增量型定位装置与电子绘图设备的画笔属性绑定。 对于一维定 位装置, 由于其仅有一个矢量, 因此可以与一种画笔属性绑定; 对于二维定位装置, 由于其具有两个矢量, 因此可以与两种画笔属性绑定。 如果画笔属性有六种 (色相、 饱和度、 亮度、 粗细、 硬度、 透明度), 为了实现对所有画笔属性的调整, 可以在电 子绘图设备上安装多个增量型定位装置。例如,可以安装六个一维定位装置各绑定一 种画笔属性, 或者安装三个二维定位装置各绑定两种画笔属性。或者一维定位装置和 二维定位装置结合使用, 比如安装两个二维定位装置以绑定四种画笔属性, 并另外安 装两个一维定位装置以绑定剩余两种画笔属性;或者安装一个二维定位装置绑定两种 画笔属性, 并安装四个一维定位装置以绑定剩余四种画笔属性。如果仅仅实现选取颜 色的功能,即选取色相、饱和度和亮度三种属性值,则至少要安装三个一维定位装置, 或一个一维定位装置与一个二维定位装置才能直接与相应的属性进行绑定。
另外, 也可以将本实施例的定位装置与现有的其他画笔属性设置方式结合使用。 例如,现有的画笔属性设置方式是在画笔笔尖上安装压力传感器和计算画笔接触屏幕 的时间, 以各绑定一种画笔属性, 则根据本实施例的方法, 还可以在电子绘图设备上 安装四个一维定位装置, 各绑定一种画笔属性, 或者安装两个二维定位装置, 各绑定 两种画笔属性, 或者同时安装两个一维定位装置和一个二维定位装置,来绑定这四种 画笔属性。
当然, 虽然至少安装四个一维定位装置, 或两个二维定位装置才能实现较方便的 画笔属性调整功能,但是也可以只安装一至三个一维定位装置或者一个二维定位装置 以绑定一部分画笔属性以便对某个常用画笔属性进行调整。例如仅使用一个含有旋转 编码器的一维旋转定位装置绑定画笔硬度,而其他属性仍然使用传统的设置方法进行 设置, 或使用一个含有轨迹球的二维旋转定位装置绑定画笔的色相和饱和度,其他属 性仍然使用传统设置方法进行设置。
需要说明的是, 可以在同一个电子绘图设备上安装上述多个定位装置, 也可以在 不同的电子绘图设备上安装上述多个定位装置,例如,在电子画笔上安装其中一个一 维定位装置,在电子画板上安装其中一个二维定位装置, 再在电子调色板上安装其中 一个一维定位装置, 由此实现了四种画笔属性与增量型定位装置的绑定。 以上安装方 式只是举例说明, 本实施例并不以此作为限制, 在具体实施时, 本领域技术人员可以 根据需要或者操作便利性实施其他的安装方式, 其内容都包含于本发明实施例的范 围。
在本实施例中, 当通过步骤 101检测到增量型定位装置的位置发生变化时, 即可 通过步骤 102根据位置变化信息调整该增量型定位装置对应的画笔属性的属性值,通 过调整画笔属性的属性值,可以改变相应的画笔形态, 以及当前属性值的指示标志在 该属性矢量空间中的位置。
在一个实施方式中,电子绘图设备自身存储并可以修改画笔属性,例如电子画板。 需要调整画笔属性时, 该设备直接执行步骤 102, 也即, 根据步骤 101检测到的定位 装置的位置变化信息, 调整相应的画笔属性。在该实施方式中, 增量型定位装置可以 是安装于画板的增量型定位装置, 也可以是安装于其他电子绘图设备(例如画笔或调 色板)的增量型定位装置。 如果是安装于其他电子绘图设备的增量型定位装置, 则当 检测出该增量型定位装置的位置变化后,通过有线或无线的方式将该位置变化的信息 发送给画板, 由画板执行画板属性调整的功能。
在另一个实施方式中, 电子绘图设备不具有存储和修改画笔属性值的功能, 例如 电子画笔、 电子调色板。该设备上的增量型定位装置在通过步骤 101检测到其位置变 化后,相应的位置变化信息通过有线或无线的方式被发送给存储并可以修改画笔属性 的设备, 例如电子画板, 由画板执行画笔属性调整功能。
在本实施例中, 将增量型定位装置与画笔属性绑定在一起, 则对增量型定位装置 的操作转化为对相应的画笔属性的属性值的调整。所以增量型定位装置为被绑定的属 性值所专用, 一个位移矢量只能绑定一种属性。在本实施例中, 对于绑定方式不做限 制,只要是能实现将对增量型定位装置的操作转化为对相应的画笔属性的属性值的调 整, 都包含于本发明实施例的范围。 通过本发明实施例的方法, 使得绘图时能够精确而快速地调整画笔属性, 甚至能 够让视线不离开绘图区域, 提高了绘图效率。 实施例 2
本发明实施例还提供了一种电子绘图设备, 该电子绘图设备可以是画板等具有存 储和修改画笔属性值的功能的设备, 但本实施例并不以此作为限制。
图 2是该电子绘图设备的组成示意图, 请参照图 2, 该电子绘图设备中含有: 至少一个增量型定位装置 21, 每一个定位装置 21检测通过用户对该定位装置 21 的操作而产生的位置变化;
控制部 22,其根据每一个定位装置检测到的位置变化调整与所述定位装置绑定的 画笔属性的属性值。
在本实施例中, 如前所述, 该至少一个增量型定位装置 21 可以都是一维定位装 置,也可以都是二维定位装置,还可以是一部分一维定位装置和一部分二维定位装置。 其中, 一维定位装置可以是使用角位移传感器如机械、光电或霍尔型旋转编码器制成 的旋转定位装置, 外观是旋钮、滚轮或拨盘形态; 二维定位装置可以是使用轨迹球制 成的二维旋转定位装置, 也可以是使用光学触控板或电容触控板制成的平面定位装 置。其中轨迹球装置内部可能包含两个角位移传感器或一个平面位移传感器。 由于含 有旋钮、拨盘、滚轮的一维旋转定位装置和含有圆球的二维旋转定位装置对于本实施 例来说, 具有触碰点不是位置检测点使得接触动作本身不会被识别为位置变化、位移 范围没有边界、可以加入定位反馈等优点, 在使用时比较容易避免不必要的位移, 跟 直线型或平面型定位装置相比, 更适合本实施例所述的应用。
在本实施例中,可以通过在画板上安装上述至少一个定位装置 21,来检测该位置 变化(位移), 由控制部 22根据该位移调整该定位装置 21对应的画笔属性的属性值。
在本实施例的其他实施方式中, 该电子绘图设备还可以包含一个通信部 24,用于 接收来自其他电子绘图设备的定位装置的位置变化信息, 使控制部 22能够根据该位 置变化信息调整与所述其他电子绘图设备的所述定位装置绑定的画笔属性的属性值。 由此, 即便与画笔属性绑定的定位装置不是安装于本实施例的电子绘图设备, 而是安 装于其他的电子绘图设备,用户也可以通过调整该安装于其他的电子绘图设备的定位 装置, 来实现与该定位装置绑定的画笔属性的调整。 在本实施例的另外一个实施方式中, 该电子绘图设备还可以包含一个颜色拾取开 关 23, 用于使控制部 22进入颜色拾取模式, 即根据画笔的点击位置处的颜色属性值 重置画笔的颜色属性。该拾取颜色的功能可以通过按下在该电子绘图设备上安装的颜 色拾取开关 23触发,也可以通过通信部 24接收到的来自其他电子绘图设备的颜色拾 取开关信息来触发。 于是, 当用户按下对应拾取功能的开关开启拾取功能后, 用画笔 点击画板上的绘图区域, 就可以用点击位置的颜色值来重置画笔的颜色属性。 其中, 拾取功能可以实现为在按下拾取开关时开启,抬起拾取开关后关闭, 也可以实现为按 下再抬起拾取开关后开启,之后再按下再抬起拾取开关后关闭, 而开关也可以不是按 键开关而是拨动开关等其他种类, 本实施例并不以此为限。
通过本发明实施例的电子绘图设备, 可以使用户视线不离开绘图区域就能实现画 笔属性的调整, 提高了绘图效率。对于上述其他电子绘图设备, 将在以下的实施例中 进行说明。 对于本实施例的电子绘图设备与上述其他电子绘图设备之间的结合使用, 也在以下进行说明。 实施例 3
本发明实施例还提供了一种电子绘图设备, 该电子绘图设备可以是画笔、 调色板 等不具备存储和修改画笔属性的功能的设备, 但本实施例并不以此作为限制。
图 3是该电子绘图设备的组成示意图, 请参照图 3, 该电子绘图设备中含有: 至少一个增量型定位装置 31, 每一个增量型定位装置 31能够感知 (检测) 由于 用户对该增量型定位装置 31的操作而产生的位置变化;
通信部 33, 其将所述至少一个增量型定位装置 31检测到的位置变化信息发送到 其他电子绘图设备,使该其他电子绘图设备可以根据此信息调整与上述增量型定位装 置 31绑定的画笔属性的属性值。
控制部 32, 其处理所述至少一个增量型定位装置 31检测到的位置变化信息并通 过所述通信部 33发送到其他电子绘图设备, 使该其他电子绘图设备可以据此调整与 上述定位装置 31绑定的画笔属性的属性值。
在本实施例中, 定位装置 31的实现方式与实施例 1或实施例 2描述的定位装置 的实现方式相同, 其内容被合并于此, 在此不再赘述。
在本实施例中, 通信部 33可以通过现有的手段来实现, 包括各种有线或无线的 通信方式, 本实施例并不以此作为限制。
本实施例的电子绘图设备安装有与画笔属性绑定的定位装置, 用户只需要操作该 定位装置, 即可实现与该定位装置绑定的画笔属性的调整, 由此提高了绘图效率。
在本实施例中, 由于电子画板、 画笔和调色板一般结合使用, 因此在具体实施过 程中, 可以在画板、 画笔和调色板上安装对应不同画笔属性的定位装置, 由此实现对 画笔属性的分别调整, 又能节省单个电子绘图设备(画板、 画笔或调色板) 的安装空 间, 于是就不需要在同一个电子绘图设备(画板、 画笔或调色板)上安装对应所有画 笔属性的定位装置 (如果有六种画笔属性, 就可能需要安装 6个一维定位装置、 或 3 个二维定位装置、或 2个一维定位装置和 2个二维定位装置、或 4个一维定位装置和 1个二维定位装置), 方便用户辨识和操作。
在一个实施方式中, 可以在电子画板、 画笔或调色板上安装至少三个一维定位装 置, 或安装一个一维定位装置和一个二维定位装置, 以与三个画笔属性绑定。在另一 个实施方式中, 可以在画板、 画笔或调色板上安装两个二维定位装置, 以与四个画笔 属性绑定。
在一个实施方式中, 可以在电子调色板上另外安装绝对型的一维或二维定位装 置, 如电容或电磁触摸屏, 与该调色板上已有的前述绑定画笔属性的增量型一维或二 维定位装置同时使用, 也即, 一个绝对型一维定位装置或二维定位装置的某一矢量和 一个增量型一维定位装置或二维定位装置的某一矢量可以用于调整同一个画笔属性。
在本实施例的一个实施方式中, 通信部 33还可以接收其他电子绘图设备 (例如 画板)发送的画笔属性的信息(在某些场景下是原始数据, 在某些场景下可能是处理 过的数据), 以根据接收到的上述信息进行相应的处理或显示。
在该实施方式中, 当该电子绘图设备为画笔时, 该电子绘图设备还可以包含一个 画笔形态显示部 34, 用于根据通信部 33接收到的其他电子绘图设备发送的画笔属性 信息显示与当前画笔属性对应的画笔形态。其中, 画笔形态是指, 在画板上的空白绘 图区域, 以合适的压力用画笔点击一次所得到的图像, 通过该图像, 用户可以看出当 前的画笔颜色、 粗细、 硬度、 透明度等信息。 这样用户就可以不看画板或调色板上的 画笔属性窗口也能获知画笔当前的状态。每次通过本发明实施例的方法调整画笔属性 之后, 该电子绘图设备都从画板取得最新的属性信息以更新该显示内容。
在该实施方式中, 当该电子绘图设备为调色板或画笔时, 该电子绘图设备还可以 包含一个矢量空间显示部 35, 可显示包括当前正通过绑定的定位装置进行调整的某 一个或某几个画笔属性矢量的矢量空间, 并根据通信部 33接收到的其他电子绘图设 备发送的画笔属性信息, 在其中标出当前属性值的所处位置。其中, 每次通过本实施 例的方法调整画笔属性之后,该电子绘图设备都从画板取得最新的属性信息以更新该 显示内容。
在本实施例的另外一个实施方式中, 该电子绘图设备还可以包含一个颜色拾取开 关 36, 用于使画板根据画笔的点击位置处的颜色属性值重置颜色属性。 如果该电子 绘图设备自身不是画板, 则在按下拾取开关触发该功能后, 通过通信部 33告知画板 将要进行拾取颜色的操作,画板即等待画笔的点击动作以根据点击位置的颜色属性值 来重置画笔的颜色属性。 由此, 当用户按下颜色拾取开关后, 用画笔点击画板上的绘 图区域, 就可以用点击位置的颜色值来重置画笔的颜色属性。
通过本发明实施例的电子绘图设备, 使得绘图时能够精确而快速地调整画笔属 性, 甚至能够让视线不离开绘图区域, 提高了绘图效率。
为了使本实施例的方法和设备更加清楚易懂, 以下结合一些具体的实例,对本实 施例的方法和设备进行说明。
图 4是在画板上设置有定位装置的一个实施方式的示意图。如图 4所示,在画板 41的边缘安装四个用旋转编码器制成的一维旋转定位装置 42或两个用轨迹球制成的 二维旋转定位装置,分别与画笔的 HSUHue (色调), Saturation (饱和度), Lightness (亮度)) 色彩空间的三个矢量和画笔硬度属性绑定。 每次改变设置之后就通过无线 通信的方式向画笔发送最新的画笔属性信息,然后在画笔上的显示器上显示当前的画 笔形态, 即使用一个图形显示画笔的颜色、 粗细、 硬度、 透明度, 相当于画笔在画板 上点击一次的效果。 由此, 绘图时就可以让视线不离开绘图区域, 仅凭一只手靠触觉 控制即可。
图 5是在画笔上安装有定位装置的一个实施方式的示意图。如图 5所示,在画笔 51上安装两个用轨迹球制成的二维旋转定位装置 52, 通过与画板之间的无线通信来 远程控制相关的画笔的属性。同样在改变属性之后由画板向画笔发送画笔属性信息并 显示当前的画笔形态。 其中, 53为前述用于从画板上拾取颜色的颜色拾取按钮开关, 54为用于显示画笔形态的显示屏。
图 6是在画笔上安装有定位装置的另一个实施方式的示意图。如图 6所示,在画 笔 61上安装三个用旋转编码器制成的一维旋转定位装置 62, 通过与画板之间的无线 通信来远程控制相关的画笔的属性。如果其中一个旋转定位装置检测到位置移动, 即 在笔端的显示器上显示与此旋转定位装置绑定的画笔属性的调整范围矢量空间。例如 三个一维旋转定位装置分别绑定画笔的三种颜色属性,当其中绑定画笔色相属性的旋 转定位装置检测到位置移动时,就在上述显示器上以颜色条的形式显示整个可以调整 的色相范围, 并在当前属性值所在位置处显示一个光标。 属性信息同样由画板保存, 更改属性之后由画板向画笔发送画笔属性信息并更新当前的画笔形态。 其中, 63 为 显示上述与笔上的定位装置绑定的画笔属性矢量空间的显示屏。
图 7是在调色板上安装有定位装置的一个实施方式的示意图。如前所述, 该调色 板 71含有定位装置和通信部。 在该实施方式中, 该定位装置包括两个用轨迹球制成 二维旋转定位装置 711以及三个用旋转编码器制成的一维旋转定位装置 712。 此外, 该调色板还具有显示部, 如图 7所示, 该显示部具有四个显示区域, 分别是画笔硬度 属性显示区域 721、 透明度属性显示区域 722、 色彩饱和度和亮度的矢量空间显示区 域 723、 以及色调属性显示区域 724。 当该调色板通过通信部接收到画板发送的画笔 属性的信息时, 通过该显示部在前述显示区域显示相应的画笔属性。此外, 在该实施 方式中, 该调色板还具有一个颜色拾取开关 73, 用于触发前述拾取颜色属性值的功 能,也即,根据画笔在画板上所点击的位置处的颜色信息,实现画笔颜色属性的重置。 在本实施方式中,上述两个二维旋转定位装置 711中的一个与饱和度和亮度矢量空间 显示区域 723绑定, 另一个的两个矢量则分别与色调和透明度绑定; 上述三个一维旋 转定位装置 712中的一个与画笔的硬度属性绑定, 另两个分别与切换色彩空间、切换 预设画笔类型的功能绑定。 其中预设画笔的类型包括铅笔、 毛笔、 水彩笔等。 用户可 以通过操作上述定位装置来更改画笔属性,也可以直接用画笔在显示器上点击以设置 属性。在本实施方式中, 画笔的笔尖与压力传感器相连, 而压力传感器与画笔粗细属 性绑定,所以调色板上不需要对画笔粗细进行设置。此外画笔在绘图时的笔尖按下时 间与画笔的透明度绑定,所以调色板上也不需要对画笔透明度进行设置(取决于画笔 的功能和用户的喜好, 用户也可能不这样使用)。 在改变属性之后, 画板向调色板发 送画笔属性信息并更新其显示内容。如果画笔上具备显示画笔形态功能的话,在改变 属性之后画板也向画笔发送画笔属性信息并在画笔上显示当前的画笔形态。与画笔上 显示的画笔形态相比,调色板上显示了画笔属性的整个调整范围, 使用户能够很快设 置到希望的属性值。这种方式还适合用在使用常规的触摸屏计算机, 也就是画板上没 有能够与画笔属性绑定的增量型定位装置, 或者画笔上不能显示画笔形态的场合。调 色板使用无线通信的方式向画板发送控制指令和获得当前的画笔属性。
本发明以上的方法和装置可以由硬件实现, 也可以由硬件结合软件实现。本发明 涉及这样的计算机可读程序, 当该程序被逻辑部件所执行时, 能够使该逻辑部件实现 上文所述的装置或构成部件, 或使该逻辑部件实现上文所述的各种方法或步骤。逻辑 部件例如现场可编程逻辑部件、微处理器、 计算机中使用的处理器等。本发明还涉及 用于存储以上程序的存储介质, 如硬盘、 磁盘、 光盘、 DVD、 flash存储器等。
以上结合具体的实施方式对本发明进行了描述,但本领域技术人员应该清楚,这 些描述都是示例性的, 并不是对本发明保护范围的限制。本领域技术人员可以根据本 发明的精神和原理对本发明做出各种变型和修改,这些变型和修改也在本发明的范围 内。
