步骤S1502，获取用户在设置界面输入的文本信息，根据文本信息确定与文本信息关联的涂鸦字母图像的属性信息。
示例性的，文本信息包括字母或文字信息。当文本信息为多个字母时，可以不限制输入多个字母的大小写。文本信息中的每个字母与字体库或图库中对应的涂鸦字母图像相关联，根据文本信息的内容可以确定对应所需的涂鸦字母图像。
其中，涂鸦字母图像的属性信息包括重叠区域占比。如图7所示的，本申请实施例提供的涂鸦字母图像的效果示意图。如图7中的(a)图所示的重叠区域一和重叠区域二的非透明像素点的数量，或者图7中的(b)图所示的重叠区域三的非透明像素点的数量，分别所占相邻两涂鸦字母图像所有非透明像素点总数量的比值。
其中，属性信息包括每个涂鸦字母图像的倾斜角度信息。如图8所示的，本申请实施例提供的涂鸦字母图像的效果示意图。字体库中的涂鸦字母图像分别对应不同的倾斜角度。
示例性的，字体库中的每个字母可能存在倾斜角度，也可能不存在倾斜角度，如图8所示，对应标记为“1”的字母向左边倾斜，对应标记为“2”的字母无倾斜，对应标记为“3”的字母向右倾斜。
其中，涂鸦字母图像的属性信息还包括左侧边缘信息和右侧边缘信息。如图10所示的，本申请实施例提供的涂鸦字母图像的效果示意图。涂鸦字母图像可以是字体库中的字母对应显示的图像，可以根据应用场景需要手机端下载所需版本的字体库或图库。

作为一种可能的实现方式，属性信息包括第一涂鸦字母图像与第二涂鸦字母图像的重叠区域占比；若文本信息关联多个涂鸦字母图像，则执行与属性信息对应的组合命令，将涂鸦字母图像进行组合处理，包括：
获取第一涂鸦字母图像中的非透明像素点与第二涂鸦字母图像中的非透明像素点的第一总数量；获取第一涂鸦字母图像与第二涂鸦字母图像的重叠区域中的非透明像素点的第二总数量；重叠区域中的非透明像素点同时为第一涂鸦字母图像和第二涂鸦字母图像的非透明像素点；将第二总数量与第一总数量的比值作为重叠区域占比，若重叠区域占比满足预设阈值，则按重叠区域占比，将第一涂鸦字母图像和第二涂鸦字母图像进行组合处理；其中，第一涂鸦字母图像和第二涂鸦字母图像为多个涂鸦字母图像中相邻的两个图像。
示例性的，如图7所示的，为了保证相邻两个涂鸦字母图像重叠区域的平衡性，本申请实施例提供的一种处理涂鸦字母图像的效果示意图。如图7中的(a)图所示，在涂鸦字母图像“T”和“J”进行组合时，或者如图7中的(b)图所示，在涂鸦字母图像“A”和“C”进行组合时，定义任意左右两个字母重叠区域的非透明像素数量与左右两个字母所有非透明像素数量之比为重叠区域占比rate。其中，重叠区域占比rate为一个定值，可以通过如下公式一表示：
Figure PCTCN2021107892-appb-000001
其中，重叠区域占比rate为定值(例如设置为10％)；overlapOpaqueNum为任意左右相邻两个涂鸦字母图像重叠区域的非透明像素数量，即第二总数量，如图7中的(a)图中重叠区域一和重叠区域二中的非透明像素点的总数量，或者如图7中的(b)图中重叠区域三中的非透明像素点的总数量；leftOpaqueNum为左侧涂鸦字母图像的所有非透明像素点的数量；rightOpaqueNum为右侧涂鸦字母图像的所有非透明像素点的数量；将左侧涂鸦字母图像的所有非透明像素点的数量与右侧涂鸦字母图像的所有非透明像素点的数量的和，即leftOpaqueNum+rightOpaqueNum作为第一总数量。
示例性的，可以通过遍历涂鸦字母图像的非透明像素点，确定相邻的两涂鸦字母图像中分别包含的非透明像素点的数量。例如，leftOpaqueNum初始值为0，遍历左边涂鸦字母图像的所有像素点，若其像素点透明度大于0，则leftOpaqueNum＝leftOpaqueNum+1；同理，rightOpaqueNum初始值为0，遍历右边涂鸦字母图像的所有像素点，若其透明度大于0，则rightOpaqueNum＝rightOpaqueNum+1。
设定步长step(个数count＝0)，每次将重叠区域增加一个步长step(count＝count+1)，计算重 叠区域内，左侧涂鸦字母图像和右侧涂鸦字母图像中均为非透明像素点的数量(即左右两涂鸦字母图像在该位置均为非透明像素的像素点位置)。
若overlapOpaqueNum/rate＜leftOpaqueNum+rightOpaqueNum，则将重叠区域继续增加一个步长step(count＝count+1)，继续统计重叠区域非透明像素点的数量。若overlapOpaqueNum/rate≥leftOpaqueNum+rightOpaqueNum，则结束增加步长。进一步根据step*count的结果得出重叠区域对应的步进总长度。
其中，一个步长step可以设定为一定数量的像素点，具体可以根据图像的像素多少进行设定，例如将100个像素点对应一个步长。还可以设定为具体的长度，例如一个步长为1毫米，此处不做具体限定。重叠区域占比可以是一个预设的定值，例如设置为10％，还可以根据相邻两涂鸦字母图像的非透明像素点的数量进行设定，此处不做具体限定。
如图7中的(a)图所示的，在“T”和“J”的组合过程中，最终根据重叠区域一和重叠区域二中的非透明像素点对应的重叠区域占比(即根据step*count的结果得出的重叠区域对应的步进总长度)确定涂鸦字母图像的组合方式，如图7中的(b)所示，在“A”和“C”的组合过程中，最终根据重叠区域三中的非透明像素点的重叠区域占比确定组合方式。
可理解的，上述组合处理的方式只是作为示例性说明，并不限定本申请的范围，基于相同的构思的其他组合方式同样适用。
作为一种可能的实现方式，若第一涂鸦字母图像位于第二涂鸦字母图像的左侧，则重叠区域的重叠关系为第一图层位于第二图层的上一层，其中第一图层为第一涂鸦字母图像所在的图层，第二图层为第二涂鸦字母图像所在的图层。
应理解，本申请提供的实施例主要在于如何对涂鸦字母图像进行组合处理，调取字体库或图库中的涂鸦字母图像的触发方式，不限于根据输入的文本信息与涂鸦字母的关联关系进行调取，还可以是在设置界面直接显示各个涂鸦字母图像，手机在检测到用户点击相应的涂鸦字母图像的图标的操作后，直接调取涂鸦字母图像，并根据涂鸦字母图像的属性特征，对涂鸦字母图像进行组合处理。
示例性的，属性信息可以包括文本信息对应的涂鸦字母图像的左侧边缘信息和右侧边缘信息，还可以包括涂鸦字母图像的倾斜角度信息。组合命令包括组合间距命令和组合角度命令；其中，组合间距命令用于确定两两相邻的涂鸦字母图像之间的间距，组合角度命令确定组成涂鸦图案的每个涂鸦字母图像在涂鸦图案中的所在位置处的倾斜角度。
作为一种可能的实现方式，属性信息为每个涂鸦字母图像的倾斜角度信息，组合命令为组合角度命令时；若文本信息关联多个涂鸦字母图像，则执行与属性信息对应的组合命令，将涂鸦字母图像进行组合处理，包括：
根据涂鸦字母图像的倾斜角度信息和涂鸦字母图像在多个涂鸦字母图像中的位置信息的关联关系，执行与关联关系对应的所述组合角度命令，按位置信息对应的倾斜角度信息调整涂鸦字母图像的角度。
示例性的，如图8所示，字体库中的涂鸦字母图像分别对应不同的倾斜角度，为保证最后生成的涂鸦图案的聚合度，当文本信息关联多个涂鸦字幕图像时，需要按照涂鸦字母图像所在的位置调整涂鸦字母图像的角度。如表1所示的，位置信息与角度信息的对应关系。
Figure PCTCN2021107892-appb-000002
表1
可理解的，表1中的角度为涂鸦字母图像在字体库或图库中已存在的角度，包括的左倾斜、无倾斜及右倾斜，即涂鸦字母图像本身的角度信息。表1中的位置为某一涂鸦字母图像对应的字符所在文本信息中的位置，包括左一(如图9中“S”)、左二(如图9中的“T”)、右二(如图9中的“R”)及右一(如图9中的“S”)。当涂鸦字母图像本身为左倾斜，且处于左一的位置，则不调整角度，例如图9中的最左边的“S”，本身为左倾斜且处于左一的位置，则不调整角度。当涂鸦字母图像本身为无倾斜，且处于左二的位置，则向左调整5度，例如图9中的“T”，本身无倾斜且处于左二的位置，根据表1所示，向左调整5度。当涂鸦字母图像本身为左倾斜，且处于右一的位置，则向左调整20度，例如图9中的最右边的“S”，本身为左倾斜且处于右一的位置，根据表1所示，向左调整20度。当涂鸦字母图像本身为无倾斜，且处于右二的位置，则向右调整5度，例如图9中的“R”，本身无倾斜且处于右二的位置，根据表1所示，向右调整5度。
其中，相同的字母处于不同的位置时，对应不同的倾斜角度，如图9所示的最左边的“S”和最右边的“S”。
作为一种可能的实现方式，属性信息为文本信息对应的涂鸦字母图像的左侧边缘信息和右侧边缘信息，组合命令为组合间距命令时；若文本信息关联多个涂鸦字母图像，则执行与属性信息对应的组合命令，将涂鸦字母图像进行组合处理，包括：
根据第一涂鸦字母图像的右侧边缘信息和第二涂鸦字母图像的左侧边缘信息的组合对，执行与组合对对应的组合间距命令，将第一涂鸦字母图像与第二涂鸦字母图像按预设间距进行组合处理。
其中，第一涂鸦字母图像和第二涂鸦字母图像为多个涂鸦字母图像中相邻的两个图像，且第一涂鸦字母图像位于第二涂鸦字母图像的左侧，左侧边缘信息和右侧边缘信息分别用于表示涂鸦字母图像的左侧边缘和右侧边缘的形状信息。
示例性的，参照上述字体库中所有字母的左侧边缘和右侧边缘的形态，可将两两涂鸦字母图像的左侧边缘信息或右侧边缘信息组合，即将相邻两涂鸦字母图像中的左边涂鸦字母图像的右侧边缘信息与右边涂鸦字母图像的左侧边缘信息进行组合，形成组合对；根据组合对的边缘形态特征，设定与组合对对应的组合间距命令。当手机检测到任两个相邻的涂鸦字母图像的组合对满足组合对中的形状组合，则执行与组合对对应的组合间距命令，将两相邻的涂鸦字母图像按对应预设的间距进行组合。如表2所示的组合对于组合间距的对应关系。
Figure PCTCN2021107892-appb-000003
表2
应理解，在相邻两涂鸦字母图像中，组合对应为左边涂鸦字母图像的右侧边缘信息与右边涂鸦字母图像的左侧边缘信息组合成的。上述表2仅示例性说明图10中的(a)图所示的字体库的组合对所对应的组合间距，并不用于限制本申请。针对其他形态的字体库或图库，还可以预设与字体库或图库中涂鸦字母图像所关联的其他组合对及组合间距。电子设备可以根据涂鸦字母图像的组合对调用与组合对所对应组合间距命令，执行组合间距命令，将涂鸦字母进行组合处理。
示例性的，如图12所示的，本申请实施例提供的一种处理涂鸦字母图像的效果示意图。当文本信息为“AC”时，手机识别出“AC”分别对应的涂鸦字母图像的边缘信息，即“A”的右侧边缘信息和“C”的左侧边缘信息，可以确定“A”的右侧形态为R5，“C”的左侧形态为L5，则根据表2中，组合对为R5L5，R5L5对应的组合间距为16，则执行组合命令，将“A”和“C”分别对应的涂鸦字母图像(即字体库中的字体图像)按间距为16进行组合，得到如图12所示的组合效果。
可理解的，间距值可以是一个量化值，将一定数量的像素值作为一个单位的量化值，表2中的间距值的单位则对应量化值，例如将50个像素点的距离作为一个单位的量化值，那么间距值为16时，则对应16×50个像素点的距离。表2中的间距值的单位也可以是长度单位，例如毫米mm等。
作为一种可能的实现方式，生成涂鸦图案的方法还包括：
获取涂鸦字母图像的左侧边缘和右侧边缘的非透明像素点的像素坐标；根据像素坐标，确定每个涂鸦字母图像的所述左侧边缘信息和所述右侧边缘信息。
示例性的，针对未预设与涂鸦字母图像关联的左侧边缘信息和右侧边缘信息的字体库或图库，还可以根据涂鸦字母图像中左侧边缘与右侧边缘的非透明像素点的坐标，确定涂鸦字母图像的左侧边缘信息和右侧边缘信息。其中，电子设备在根据文本信息确定关联的涂鸦字母图像后，可以遍历涂鸦字母图像的左侧或右侧边缘的非透明像素点的坐标，通过遍历涂鸦字母图像左侧边缘或右侧边缘的非透明像素点，获取非透明像素点中的关键点位置处像素的坐标值，也可以获取左侧边缘或右侧边缘所有像素点的坐标值，根据关键点位置处像素的坐标值或左侧边缘或右侧边缘所有像素点的坐标值，确定涂鸦字母图像的左侧边缘的形状信息或右侧边缘的形状信息。
可理解的，针对字体库中涂鸦字母图像的形态，执行相应的组合命令，包括但不限于以上实施例提出的各种形态，还可以包括其他形态。涂鸦图案可以是由多个涂鸦字母图像组成的图案，还可 以是其他字符组成的图案。
还应理解，本申请实施例中提供的涂鸦字母图像的属性信息以及属性信息对应的组合命令仅仅作为示例，并非所有的组合处理步骤均是必须执行的步骤，或者并非各个属性信息对应的组合命令均是必选的，在使用过程中可以根据字体库或图库的涂鸦字母图像的需要使用一种组合命令或至少两种组合命令的结合使用；对于多种组合命令的结合使用方式此处不做具体限制。
例如，在执行组合角度命令后，根据重叠区域占比属性执行重叠组合的命令；或者在获取涂鸦字母图像的左侧边缘信息和右侧边缘信息后，未调用到与组合对相关联的组合间距命令，也可以根据重叠区域占比属性执行重叠组合的命令。
作为一种可能的实现方式，与文本信息关联的还包括涂鸦字母图像的背景图像，背景图像的大小大于涂鸦字母图像的大小，背景图像与涂鸦字母图像一一对应；生成涂鸦图案的方法还包括：
根据涂鸦字母图像的中心位置、涂鸦字母图像的大小以及背景图像的大小，计算背景图像的位置，得到多个涂鸦字母图像对应的整体背景图像；将多个涂鸦字母图像的图层设置于整体背景图像所在的图层之上，得到带边缘的涂鸦图案。
示例性的，如图13所示的，本申请实施例提供的，另一种处理涂鸦字母图像的效果示意图。背景图像可以为设置好的与字体库一同存储的，并与字体库中的涂鸦字母图像一一对应的图像，如图13中所示的单个涂鸦字母图像的背景图像。
在确定涂鸦字母图像的位置后，将背景图像的中心与对应的涂鸦字母图像的中心重合，并根据涂鸦字母图像的大小及背景图像的大小确定背景图像的位置。
如图13所示，在直角坐标系xoy中，以x为横轴，以y为纵轴，单位分别可以为像素或毫米mm。其中，涂鸦字母图像“H”的位置坐标为(x1,y1),为根据涂鸦字母图像在显示区域的位置已确定的。涂鸦字母图像的中心位置为O1(x0,y0)，将背景图像的中心O2与涂鸦字母图像的中心重合，根据涂鸦字母图像的大小(包括高h1、宽w1)、背景图像的大小(包括高h2、宽w2)，计算背景图像的位置坐标(x2，y2)。
其中，O1的坐标为(x1+w1/2,y1+h1/2)，则背景图像的位置坐标(x2,y2)为(x1+(w1-w2)/2,y1+(h1-h2)/2)。从而可以确定每个涂鸦字母图像的背景图像的位置。将多个涂鸦字母图像的图层设置于整体背景图像所在的图层之上，得到带边缘的涂鸦图案。
作为一种可能的实现方式，在电子设备的熄屏界面、锁屏界面或相机拍摄界面显示涂鸦图案。在电子设备显示涂鸦图案还包括在智能手表的锁屏状态或解锁状态显示涂鸦图案，即涂鸦图案作为智能手表的锁屏图案或解锁图案。如图14所示的，本申请实施例提供的电子设备显示界面显示涂鸦图案的示意图，通过上述实施例，生成智能手表表盘的解锁涂鸦图案。
通过本申请实施例，在电子设备的涂鸦图案设置界面，电子设备可以接收用户输入的文本信息。电子设备根据文本信息对应关联的涂鸦字母图像的属性信息，对涂鸦字母图像进行组合处理。从而可以根据不同的涂鸦字母图像生成多种涂鸦图案，无需电子设备预先下载并存储大量图片而占用存储空间；节省电子设备的存储空间，提高并丰富了电子设备的个性化应用的性能；满足了用户对电子设备的个性化需求。
