为使本发明的目的、技术方案及优点更加清楚、明确,以下参照附图并举实施例对本发明进一步详细说明。

本发明提供一种移动终端的图片放大显示的方法,采用一种模糊操作的手段实现图片的放大。该方法应用于采用触摸屏的移动终端上对图片的操作,该方法优选实施的流程如图 1
所示。
S100 ,将图片划分为 M × N 个矩形组成的阵列;图片划分的矩形阵列如图 2 所示。图 2
示出了图片 90 被划分为 M × N 个矩阵,对矩阵中每一个矩形按照该矩形在阵列中的行列位置进行编号,编号采用数组存储结构表达为 [1][1] ,…
[1][N] ,… [M][1] ,… [M][N] ,即设定矩阵中某一个矩形的编号为 [a][b] 时,其中, a , b 分别满足 1 ≤ a ≤ M ,
1 ≤ b ≤ N 。
S200 ,当检测到图片上的触摸点为两个时,获取该两个触摸点所在的矩形。具体步骤包括:
首先,获取两个触摸点在移动终端触摸屏上的坐标( x , y
)。对于采用触摸屏的移动终端来说,图片操作需要检测触摸屏上的触摸点,本方法优选实施例中采取获取触摸点进行图片放大操作需要锁定触摸点为两个才确认为对图片进行放大操作,否则放弃检测操作进行重新检测。锁定触摸点需要在触摸屏被触摸时,移动终端的***获取触摸点的坐标,并对各触摸点的坐标同时满足在一预定时间内未变化时才确认所检测到的触摸点的坐标被锁定,此时,才能进一步判断触摸点坐标所在图片矩形阵列中矩形的位置。
然后,判断两个触摸点坐标( x , y )的横坐标值 x 、纵坐标值 y
分别位于所述阵列中的矩形范围,以确定两个触摸点所在的矩形。确定触摸点所在的矩形时,需要计算两个触摸点坐标( x , y
),由于两个触摸点坐标的计算过程相同,此处仅以一个触摸点坐标( x , y )为例进行说明,判断
x[a1][b1] ≤ x< x[a1][b1]' 且
y[a1][b1] ≤ y< y[a1][b1]' ,
则触摸点坐标( x,y )位于编号为 [a1][b1] 的矩形内,其中,
x[a1][b1] 为编号为 [a1][b1]
的矩形的左下角的横坐标, y[a1][b1] 为编号为
[a1][b1] 的矩形的左下角的纵坐标, x[a1][b1]'
为编号为 [a1][b1] 的矩形的右上角的横坐标,
y[a1][b1]' 为编号为 [a1][b1]
的矩形的右上角的纵坐标。
S300 ,将两个触摸点所在的矩形行与列之间的矩形阵列放大显示。放大显示操作根据步骤 S200
中得到的两个触摸点所在的矩形编号,根据该矩形的编号查找两个触摸点中所在矩形的行、列位置;再确定两个触摸点所在矩形的行、列之间的矩形阵列并放大显示。根据步骤
S200 中的触摸点坐标( x , y )查找矩形编号的例子,在确定两个触摸点所在的矩形编号 [a][b]
后,***通过两个触摸点的矩形编号将两个触摸点的行、列之间的矩形阵列组成的区域放大进行显示,设两个触摸点分别为
[a1][b1] 、 [a2][b2] ,要放大的矩形包括矩形编号为
[az][bz]

, y ),由于两个触摸点坐标的计算过程相同,此处仅以一个触摸点坐标( x , y )为例进行说明,需要计算
x[a1][b1] ≤ x< x[a1][b1]' 且
y[a1][b1] ≤ y< y[a1][b1]' ,
则触摸点坐标( x,y )位于编号为 [a1][b1] 的矩形内,其中,
x[a1][b1] 为编号为 [a1][b1]
的矩形的左下角的横坐标, y[a1][b1] 为编号为
[a1][b1] 的矩形的左下角的纵坐标, x[a1][b1]'
为编号为 [a1][b1] 的矩形的右上角的横坐标,
y[a1][b1]' 为编号为 [a1][b1]
的矩形的右上角的纵坐标。
显示放大模块 30
用于根据所述矩形的编号查找两个触摸点中所在矩形的行、列位置;并确定两个触摸点所在矩形的行、列之间的矩形阵列以放大显示。放大显示操作根据触摸检测模块 20
检测得到的两个触摸点所在的矩形编号,根据该矩形的编号查找两个触摸点中所在矩形的行、列位置;再确定两个触摸点所在矩形的行、列之间的矩形阵列并放大显示。在确定两个触摸点所在的矩形编号
[a][b] 后,***通过两个触摸点的矩形编号将两个触摸点的行、列之间的矩形阵列组成的区域放大进行显示,设两个触摸点分别为
[a1][b1] 、 [a2][b2] ,要放大的矩形包括矩形编号为
[az][bz]
的所有矩形,其中,a1≤az≤a2,b1≤bz≤b2。
本发明方法和***优选实施例将当前显示图片划分为由 M×N
个矩形所组成的阵列,并对所述阵列中每一个矩形进行编号;当检测到触摸屏被触摸,当所检测到的触摸点的坐标锁定后,获取触摸点的个数,若为2个则判断触摸点所位于的所述阵列中矩形的编号;根据所得两个矩形的编号确定图片中放大显示的区域,并进行放大显示。本发明达到
使图片通过一种模糊操作达到放大显示的目的,以增加放大的精度并实现多次操作放大相同区域的目的,同时为用户的使用提供了方便。
