+2020-01-08：
+
+修复了工具当前预览的图片被锁定无法外部修改的问题
+
+2019-12-22：
+
+增加了图片批量转换，并将图片名称作为转换后的文件名和变量名
+1. 由于图片名可能作为转换后的变量名，增加了对图片名的规范检测，大体同前一个版本的lv_img_dsc_t检测一致
+2. 根据lvgl支持的图片种类做了分类
+3. 对各个图片加了转换前的检测结果及转换后的转换结果的tip提示
+大致如下：
+
+
+![批量转换示意图](https://images.gitee.com/uploads/images/2020/0423/101323_df096bf2_5033673.png)
+
+
+2019-11-20：
+
+增加了对转换操作结果的验证，避免了转换图片时界面卡死的问题
+
+添加了原php环境下的内存限制设置参数
+
+对于转换提示的问题：
+
+1.在转换图片时，提示转换成功，但找不到转换后的文件
+
+    原因：图片分辨率过大，修改php环境内存限制参数
+		
+  	解决办法：修改转换工具根目录下php.ini配置文件 
+```php
+memory_limit = _xxx_M	//	_xxx_ 根据实际使用修改该值，图片分辨率越大，需要设置的值就越大
+```
+
+2.在转换图片时，提示转换失败
+		
+    原因1：图片分辨率过大，转换时间太长（这么大的图片……），超时了
+    原因2：图片资源编码问题，测试发现截屏保存的图片不能直接转换，否则转换失败，先使用图片编辑工具打开，然后另存就可以了
+  
+ 目前发现以上问题
+

+
+## 界面如下
+设置输出文件类型，c测试没问题，bin格式没用到，如果有用到的朋友欢迎反馈
+
+![设置输出文件类型](https://images.gitee.com/uploads/images/2020/0423/100538_24dd6afd_5033673.png)
+
+转换方式跟官方网页一样
+
+![设置图片转换方式](https://images.gitee.com/uploads/images/2020/0423/100538_51e7fad4_5033673.png)
+
+lv_img_dsc_t，为生成的c文件下该图片资源的名字
+
+
+2019-11-15：
+
+## 说明
+
+软件为基于LVGL离线版图片转换封装的小工具，避免了常使用界面工具的朋友操作控制台指令的不便利
+
+运行环境为windows
+
+修改了原官方离线版php文件接口，便于保存到指定目录
+
+避免计算机没有php环境，在工具所在目录配置了一个php小环境（人懒，php不懂瞎裁）
+
+
+
+## 初衷
+
+手头项目用到lvgl做界面设计，前期在lvgl官网做图片转换，感觉挺好 但界面嘛，美观度重口难调，所以这周把界面元素重设计了一遍， 然后昨天在官网做转换时，下载n次失败……所以就有了这个基于官方离线版封装的转换工具，有问题可以通过软件界面的qq和邮箱联系我
+
+## 后续
+
+如果后面有时间或者用到的话，加一个批量转换的。。。这个先用吧
