 本发明的最佳实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
为了解决现有终端不能对笔记进行局部二次编辑的问题，本发明实施例提供了一种笔记局部选取方法，该方法可以实现对终端屏幕上的笔记进行局部选取以及对所选取的笔记局部进行二次编辑操作，简化了二次编辑的操作方法，并提升了二次编辑的操作效率及准确率，可以有效避免局部区域外的误操作，提升用户使用体验。
参考图1，为本发明一实施例提供的一种笔记局部选取方法的流程示意图。该笔记局部选取方法可以应用于显示终端，其中，该显示终端的显示区域可以用于显示笔记。可选的，该显示终端包括但不限于智能手机、智能手表、平板电脑等。进一步地，该显示终端的操作***包括但不限于Android操作***、iOS操作***、Windows操作***、Linux操作***等。
具体的，如图1所示，本发明实施例提供的笔记局部选取方法可以包括以下步骤：
步骤S1、获取笔记信息。
本发明实施例中，笔记可以通过读取存储在存储装置中的笔记得到，或者通过用户编辑产生，也可以通过网络接收笔记，或者还可以通过近距离无线传输的方式接收笔记，或者可以通过有线传输的方式接收笔记等。本发明实施例可以通过多种方式获取笔记。
可选的，本发明实施例的笔记包括汉字，其中，笔记局部可以为汉字的一个或多个笔划，或者一个或多个笔划的局部。
当然，可以理解地，在其他一些实施例中，本发明实施例的笔记还包括图画，其中，笔记局部包括图画的一部分。可选的，图画可以为任意图片。
进一步地，本发明实施例的笔记还可以为英文字母、线条等，笔记局部为英文字母的一部分或者多个部分，或者笔记局部为线条的一部分等。本发明实施例为用户提供多种形式，并不限于本文所描述的方式。
可选的，本发明实施例的笔记局部选取方法可以通过显示终端接收用户输入的启动笔记局部选取操作指令。其中，用户输入的启动笔记局部选取操作指令可以包括但不限于用户输入的动作指令（如触摸操作产生的指令，或者按键操作产生的指令）或者语音指令。用户输入的动作指令可以为双击、单击、拖动、划动、长按等，或者几种的组合。
启动笔记局部选取操作后，即获取笔记信息。其中，笔记信息包括笔记中的所有像素点的坐标数据。
步骤S2、接收并执行用于指示将预定形状图形显示在显示终端的指令。
可选的，本发明实施例中，预定形状图形预存储在显示终端的存储装置。
本发明实施例中，用于指示将预定形状图形显示在显示终端的指令可以通过用户输入的选择指令产生。具体的，用户输入的选择指令可以包括但不限于用户输入的动作指令（如触摸操作产生的指令，或者按键操作产生的指令）或者语音指令。用户输入的动作指令可以为双击、单击、拖动、划动、长按等，或者几种的组合。在一非限制性实施例中，该指令包括所述预定形状图形的尺寸，以及其位于显示终端的具***置。进一步地，通过点击选中一预定形状图形，并拖动对该预定形状图形至该具***置。
显示终端在接收到用户输入选择指令后，根据用户所输入的选择指令从存储装置中读取出与选择指令对应的预定形状图形，并将所读取的预定形状图形显示在显示终端的显示区域。
进一步地，在接收用于指示将预定形状图形显示在显示终端的指令之后，本发明实施例的笔记局部选取方法还包括：
接收并执行将预定形状图形纵向扩大或缩小、横向扩大或缩小或者纵横等比例扩大或缩小、移动的指令。
具体的，在根据用于指示将预定形状图形显示在显示终端的指令将所选择的预定形状图形显示在显示终端后，当用户需要对所选取的预定形状图形的大小、尺寸进行修改时，可以通过输入相应的修改指令（如将预定形状图形纵向扩大或缩小、横向扩大或缩小或者纵横等比例扩大，或者纵横等比例缩小的指令，或者移动的指令），由显示终端接收并根据用户输入的修改指令执行对应的编辑动作。例如，显示终端根据所接收的用户输入的将预定形状图形纵向扩大的指令，执行将预定形状图形沿纵向扩大的动作，使预定形状图形沿纵向扩大；或者，显示终端根据所接收的用户输入的将预定形状图形纵向缩小的指令，执行将预定形状图形沿纵向缩小的动作，使预定形状图形沿纵向缩小。通过根据用户输入的将预定形状图形修改为所需要的大小、尺寸等，满足了用户的编辑需求，使笔记局部选取方法更加个性化，进一步提升用户使用体验。
可选的，本发明实施例的预定形状图形可以为闭合线条。作为选择，该闭合线条可以为圆形、椭圆形、三角形、正方形、长方形、菱形、梯形中的至少一项。
作为示例，在一个具体实施例中，显示终端可以根据用户输入的选择指令，从预存在存储装置中的预定形状图形中读取一个与选择指令对应的预定形状图形，并将所读取的预定形状图形显示在显示终端上。其中，所读取的预定形状图形以圆形为例，若接收到将该圆形沿纵向扩大的指令，则根据该指令将圆形沿纵向扩大，以获得用户所需的图形。
步骤S3、遍历笔记中的所有像素点，选取所有被预定形状图形包围的像素点集合，像素点集合为选取的笔记局部。
如图3所示，作为示例，图3中的圆形101即为显示在显示终端100的预定形状图形，图中的曲线102即为在显示终端100上的笔记，图中包围在圆形101内部的曲线103即为所选取的笔记局部。
可选的，本发明实施例的笔记局部选取可以通过以下方式获得：
首先，先判断所获取的笔记中的所有像素点中的任一像素点是否位于预定形状图形所在的最小矩形区域内。
其中，判断笔记中的所有像素点的任一像素点是否位于预定形状图形所在的最小矩形区域内可以通过以下方式进行判断：
获取预定形状图形的图形坐标数据，图形坐标数据包括预定形状图形的横坐标的最大值和最小值，以及纵坐标的最大值和最小值；然后，判断所有像素点中的任一像素点的横坐标是否大于预定形状图形的横坐标的最小值、且小于预定形状图形的横坐标的最大值，以及任一像素点的纵坐标是否大于预定形状图形的纵坐标的最小值、且小于预定形状图形的纵坐标的最大值。本发明实施例中，笔记的所有像素点的坐标数据与预定形状图形的图形坐标数据是基于同一坐标系的。
具体示例参考图4，图4中A（x 0，y 0）为笔记中的所有像素点的坐标数据中的任意一个像素点，其中x 0为该像素点A的横坐标，y 0为该像素点A的纵坐标；预定形状图形（图4以圆形101为例）的横坐标的最小值为x min，预定形状图形的横坐标的最大值为x max，预定形状图形的纵坐标的最小值为y min，预定形状图形的纵坐标的最大值为y max。如图4所示，当该像素点A（x 0，y 0）满足：
x min＜x 0＜x max，且y min＜y 0＜y max时，则可以确定，该像素点A（x 0，y 0）在预定形状图形的最小矩形区域内。
可以理解地，笔记中的所有像素点中的其他像素点均可以按照上述的方来判断是否在预定形状图形所在的最小矩形区域内。
其次，当确定该像素点位于预定形状图形所在的最小矩形区域内后，进一步地判断该像素点是否在预定形状图形内。在一具体实例中，该预定形状图形为矩形，则该以预定形状图形所在的最小矩形区域即为其本身，因此，不需再执行步骤“判断该像素点是否在预定形状图形内”。这里的“最小矩形区域”表示经过该预定形状图形中具有最大纵坐标的坐标点的平行于横坐标的第一直线、经过该预定形状图形中具有最小纵坐标的坐标点的平行于横坐标的第一直线、经过该预定形状图形中具有最大横坐标的坐标点的平行于纵坐标的第三直线、经过该预定形状图形中具有最小横坐标的坐标点的平行于纵坐标的第四直线交叉构成的闭合区域。
其中，判断该像素点是否在预定形状图形内可以通过以下方式实现：
第一种方式：判断该预定形状图形中与该像素点横坐标相同的图形像素点的数量是否为2、且与该像素点横坐标相同的2个图形像素点在该像素点的两侧。
如图5所示，A（x 0，y 0）为笔记中的所有像素点的任意一个像素点，其中x 0为该像素点A的横坐标，y 0为该像素点A的纵坐标。预定形状图形（圆形101）中与像素点A（x 0，y 0）的横坐标相同的2个图形像素点分别为：图形像素点B（x 0，y b）和图形像素点C（x 0，y c）。
如图5所示，图形像素点B（x 0，y b）和图形像素点C（x 0，y c）的横坐标与像素点A（x 0，y 0）的横坐标相同，且图形像素点B（x 0，y b）和图形像素点C（x 0，y c）在像素点A的两侧，即图形像素点B的纵坐标y b和图像像素点C的纵坐标y c满足：
y b＜y 0＜y c；或者，y c＜y 0＜y b。
其中，图5示例的仅是：图形像素点B的纵坐标y b和图像像素点C的纵坐标y c满足y b＜y 0＜y c的条件。
因此，当该像素点A（x 0，y 0）满足上述条件时，则可以判定像素点A（x 0，y 0）在圆形101内。
第二种方式：判断该预定形状图形中与该像素点纵坐标相同的图形像素点的数量是否为2、且与该像素点纵坐标相同的2个图形像素点在像素点的两侧。
如图5所示，A（x 0，y 0）为笔记中的所有像素点的坐标数据中的任意一个像素点，其中x 0为该像素点A的横坐标，y 0为该像素点A的纵坐标。预定形状图形（圆形101）中与像素点A（x 0，y 0）的横坐标相同的2个图形像素点分别为：图形像素点E（x e，y 0）和图形像素点F（x f，y 0）。
如图5所示，图形像素点B（x e，y 0）和图形像素点F（x f，y 0）的横坐标与像素点A（x 0，y 0）的横坐标相同，且图形像素点E（x e，y 0）和图形像素点F（x f，y 0）在像素点A的两侧，即图形像素点E的横坐标x e和图像像素点F的横坐标x f满足：
x e＜x 0＜x f；或者，x f＜x 0＜x e。
其中，图5示例的仅是：图形像素点E的横坐标x e和图像像素点C的横坐标x f c满足x e＜x 0＜x f的条件。
因此，当该像素点A（x 0，y 0）满足上述条件时，则可以判定像素点A（x 0，y 0）在圆形101内。
本发明实施例遍历笔记中的所有像素点，以选取所有被预定形状图形包围的像素点集合，以得到所需要选取的笔记局部，满足了用户对笔记进行局部选取的需求，提升了用户使用体验。
进一步地，本发明实施例的笔记局部选取方法简单、计算量少，在提升用户使用体验的同时，还可以降低显示终端的性能消耗。
参考图2，为本发明一实施例提供的笔记局部选取方法的流程示意图。该实施例的笔记局部选取方法在前述实施例的基础上，进一步包括以下步骤：
步骤S4、对笔记局部进行编辑。
其中，步骤S4是在步骤S3完成后执行的，即完成笔记局部确定后，再执行对笔记局部的编辑操作。

综上，解决了现有无法选取局部区域，对局部区域进行二次编辑的问题，并且笔记局部选取方法简单，大大减少了计算量，降低了查找复杂度，降低终端的性能消耗，同时还可以有效提升用户使用体验。
参考图7，本发明一实施例还提供了一种笔记局部选取装置，可以用于实现前述的笔记局部选取方法。该笔记局部选取装置可以应用于显示终端，且该笔记局部选取装置的笔记显示于显示终端。可选的，该显示终端包括但不限于智能手机、智能手表、平板电脑等。进一步地，该显示终端的操作***包括但不限于Android操作***、iOS操作***、Windows操作***、Linux操作***等。
如图7所示，本发明实施例提供的笔记局部选取装置可以包括：
获取单元701，用于获取笔记信息。
本发明实施例中，笔记可以通过读取存储在存储装置中的笔记得到，或者通过用户编辑产生，也可以通过网络接收笔记，或者还可以通过近距离无线传输的方式接收笔记，或者可以通过有线传输的方式接收笔记等。本发明实施例可以通过多种方式获取笔记。
可选的，本发明实施例的笔记包括汉字，其中，笔记局部可以为汉字的一个或多个笔划，或者一个或多个笔划的局部。
当然，可以理解地，在其他一些实施例中，本发明实施例的笔记还包括图画，其中，笔记局部包括图画的一部分。可选的，图画可以为任意图片。
进一步地，本发明实施例的笔记还可以为英文字母、线条等，笔记局部为英文字母的一部分或者多个部分，或者笔记局部为线条的一部分等。本发明实施例为用户提供多种形式，并不限于本文所描述的方式。
可选的，本发明实施例的笔记局部选取方法可以通过显示终端接收用户输入的启动笔记局部选取操作指令。其中，用户输入的启动笔记局部选取操作指令可以包括但不限于用户输入的动作指令（如触摸操作产生的指令，或者按键操作产生的指令）或者语音指令。用户输入的动作指令可以为双击、单击、拖动、划动、长按等，或者几种的组合。
启动笔记局部选取操作后，即获取笔记信息。其中，笔记信息包括笔记中的所有像素点的坐标数据。
第一接收执行单元702，用于接收并执行用于指示将预定形状图形显示在显示终端的指令。
可选的，本发明实施例中，预定形状图形预存储在显示终端的存储装置。
本发明实施例中，用于指示将预定形状图形显示在显示终端的指令可以通过用户输入的选择指令产生。具体的，用户输入的选择指令可以包括但不限于用户输入的动作指令（如触摸操作产生的指令，或者按键操作产生的指令）或者语音指令。用户输入的动作指令可以为双击、单击、拖动、划动、长按等，或者几种的组合。
显示终端在接收到用户输入选择指令后，根据用户所输入的选择指令从存储装置中读取出与选择指令对应的预定形状图形，并将所读取的预定形状图形显示在显示终端的显示区域。
进一步地，在接收用于指示将预定形状图形显示在显示终端的指令之后，第一接收执行单元702还用于：接收并执行将预定形状图形纵向扩大或缩小、横向扩大或缩小或者纵横等比例扩大或缩小、移动的指令。
具体的，在根据用于指示将预定形状图形显示在显示终端的指令将所选择的预定形状图形显示在显示终端后，当用户需要对所选取的预定形状图形的大小、尺寸进行修改时，可以通过输入相应的修改指令（如将预定形状图形纵向扩大或缩小、横向扩大或缩小或者纵横等比例扩大，或者纵横等比例缩小的指令，或者移动的指令），由第一接收执行单元702接收并根据用户输入的修改指令执行对应的编辑动作。例如，第一接收执行单元702根据所接收的用户输入的将预定形状图形纵向扩大的指令，执行将预定形状图形沿纵向扩大的动作，使预定形状图形沿纵向扩大；或者，第一接收执行单元702根据所接收的用户输入的将预定形状图形纵向缩小的指令，执行将预定形状图形沿纵向缩小的动作，使预定形状图形沿纵向缩小。通过根据用户输入的将预定形状图形修改为所需要的大小、尺寸等，满足了用户的编辑需求，使笔记局部选取方法更加修改个性化，进一步提升用户使用体验。
可选的，本发明实施例的预定形状图形可以为闭合线条。作为选择，该闭合线条可以为圆形、椭圆形、三角形、正方形、长方形、菱形、梯形中的至少一项。
作为示例，在一个具体实施例中，第一接收执行单元702可以根据用户输入的选择指令，从预存在存储装置中的预定形状图形中读取一个与选择指令对应的预定形状图形，并将所读取的预定形状图形显示在显示终端上。其中，所读取的预定形状图形以圆形为例，若接收到将该圆形沿纵向扩大的指令，则根据该指令将圆形沿纵向扩大，以获得用户所需的图形。
选取单元703，用于遍历笔记中的所有像素点，选取所有被预定形状图形包围的像素点集合，像素点集合为选取的笔记局部。
具体的，选取单元703包括：第一判断模块、第二判断模块和选取模块。
本发明实施例中，第一判断模块，用于判断所有像素点中的任一像素点是否位于预定形状图形所在的最小矩形区域内。
进一步地，第一判断模块包括：
子获取模块，用于获取预定形状图形的图形坐标数据，图形坐标数据包括预定形状图形的横坐标的最大值和最小值，以及纵坐标的最大值和最小值。
子判断模块，用于在确定该像素点位于预定形状图形所在的最小矩形区域内后，进一步判断该像素点是否在预定形状图形内。其中，子判断模块具体可以通过以下两种方式进行判断：判断所有像素点中的任一像素点的横坐标是否大于预定形状图形的横坐标的最小值、且小于预定形状图形的横坐标的最大值，以及任一像素点的纵坐标是否大于预定形状图形的纵坐标的最小值、且小于预定形状图形的纵坐标的最大值。
具体示例参考图4，图4中A（x 0，y 0）为笔记中的所有像素点的坐标数据中的任意一个像素点，其中x 0为该像素点A的横坐标，y 0为该像素点A的纵坐标；预定形状图形（图4以圆形101为例）的横坐标的最小值为x min，预定形状图形的横坐标的最大值为x max，预定形状图形的纵坐标的最小值为y min，预定形状图形的纵坐标的最大值为y max。如图4所示，当该像素点A（x 0，y 0）满足：
x min＜x 0＜x max，且y min＜y 0＜y max时，则可以确定，该像素点A（x 0，y 0）在预定形状图形的最小矩形区域内。
可以理解地，笔记中的所有像素点中的其他像素点均可以按照上述的方来判断是否在预定形状图形所在的最小矩形区域内。
第二判断模块，用于在该像素点位于预定形状图形所在的最小矩形区域内时，判断该像素是否在预定形状图形内。在一具体实例中，该预定形状图形为矩形，则该以预定形状图形所在的最小矩形区域即为其本身，因此，不需再执行步骤“判断该像素点是否在预定形状图形内”。这里的“最小矩形区域”表示经过该预定形状图形中的具有最大纵坐标的坐标点的平行于横坐标的第一直线、经过该预定形状图形中具有最小纵坐标的坐标点的平行于横坐标的第一直线、经过该预定形状图形中具有最大横坐标的坐标点的平行于纵坐标的第三直线、经过该预定形状图形中具有最小横坐标的坐标点的平行于纵坐标的第四直线交叉构成的闭合区域。
其中，第二判断模块判断该像素点是否在预定形状图形内可以通过以下方式判断：
第一种方式：判断该预定形状图形中与该像素点横坐标相同的图形像素点的数量是否为2、且与该像素点横坐标相同的2个图形像素点在该像素点的两侧。
如图5所示，A（x 0，y 0）为笔记中的所有像素点的坐标数据中的任意一个像素点，其中x 0为该像素点A的横坐标，y 0为该像素点A的纵坐标。预定形状图形（圆形101）中与像素点A（x 0，y 0）的横坐标相同的2个图形像素点分别为：图形像素点B（x 0，y b）和图形像素点C（x 0，y c）。
如图5所示，图形像素点B（x 0，y b）和图形像素点C（x 0，y c）的横坐标与像素点A（x 0，y 0）的横坐标相同，且图形像素点B（x 0，y b）和图形像素点C（x 0，y c）在像素点A的两侧，即图形像素点B的纵坐标y b和图像像素点C的纵坐标y c满足：
y b＜y 0＜y c；或者，y c＜y 0＜y b。
其中，图5示例的仅是：图形像素点B的纵坐标y b和图像像素点C的纵坐标y c满足y b＜y 0＜y c的条件。
因此，当该像素点A（x 0，y 0）满足上述条件时，则可以判定像素点A（x 0，y 0）在圆形101内。
第二种方式：判断该预定形状图形中与该像素点纵坐标相同的图形像素点的数量是否为2、且与该像素点纵坐标相同的2个图形像素点在像素点的两侧。
如图5所示，A（x 0，y 0）为笔记中的所有像素点的坐标数据中的任意一个像素点，其中x 0为该像素点A的横坐标，y 0为该像素点A的纵坐标。预定形状图形（圆形101）中与像素点A（x 0，y 0）的横坐标相同的2个图形像素点分别为：图形像素点E（x e，y 0）和图形像素点F（x f，y 0）。
如图5所示，图形像素点B（x e，y 0）和图形像素点F（x f，y 0）的横坐标与像素点A（x 0，y 0）的横坐标相同，且图形像素点E（x e，y 0）和图形像素点F（x f，y 0）在像素点A的两侧，即图形像素点E的横坐标x e和图像像素点F的横坐标x f满足：
x e＜x 0＜x f；或者，x f＜x 0＜x e。
其中，图5示例的仅是：图形像素点E的横坐标x e和图像像素点C的横坐标x f c满足x e＜x 0＜x f的条件。
因此，当该像素点A（x 0，y 0）满足上述条件时，则可以判定像素点A（x 0，y 0）在圆形101内。
选取模块，用于在该像素点位于预定形状图形所在的最小矩形区域内，并且该预定形状图形中与该像素点横坐标相同的图形像素点的数量是否为2及与像素点横坐标相同的2个图形像素点在像素点的两侧或者该预定形状图形中与该像素点纵坐标相同的图形像素点的数量是否为2及与像素点纵坐标相同的2个图形像素点在像素点的两侧时，选取该像素点。
参考图8，为本发明一实施例提供的笔记局部选取装置的原理框图。该实施例在前述实施例的笔记局部选取装置的基础上，进一步还包括：编辑单元704。
具体的，编辑单元704，用于对笔记局部进行编辑，编辑包括改变颜色、合并、拆分、删除、增加、修改宽度、修改长度、纵向扩大或缩小、横向扩大或缩小或纵横等比例扩大或缩小、或移动。
可选的，本发明实施例中，编辑包括但不限于改变颜色、合并、拆分、删除、增加、修改宽度、修改长度、纵向扩大或缩小、横向扩大或缩小或纵横等比例扩大或缩小、或移动。即可以实现对所选取的笔记局部进行改变颜色的操作，对笔记局部进行合并，对笔记局部进行拆分，对笔记局部进行删除，对笔记局部进行增加，修改笔记局部的宽度，修改笔记局部的长度，纵向扩大笔记局部，纵向缩小笔记局部，横向扩大笔记局部，横向缩小笔记局部，或者纵横等比例扩大笔记局部，或者纵横等比例缩小笔记局部、或者移动笔记局部等。
进一步地，编辑单元704包括：接收执行模块。
具体的，接收执行模块，用于接收并执行针对笔记局部的颜色设置指令、笔记信息合并指令、笔记信息拆分指令、笔记信息删除指令、增加笔记指令、修改笔记宽度指令、修改笔记长度指令、缩放指令、移动指令中的至少一项。通过接收上述指令，并根据上述指令进行对应编辑操作，实现了对笔记局部的灵活调节编辑，使对笔记局部的二次编辑更加个性化、多样化。
本发明实施例中，获取单元701、第一接收执行单元702、选取单元703以及编辑单元704均设置在显示终端内。
