急急急Wifi 传图不支持高清图片吗？不支持的话，这个sensor.WQXGA2: 2592x1944 格式是咋用的

在补上一张 不支持高清图片的错误

[kidswong999]

改成

sensor.set_pixformat(sensor.JPEG)
sensor.set_framesize(sensor.WQXGA2)

然后把compressed()删掉。

注意分辨率太高了会非常慢。

@kidswong999 在 急急急Wifi 传图不支持高清图片吗？不支持的话，这个sensor.WQXGA2: 2592x1944 格式是咋用的 中说：

sensor.set_pixformat(sensor.JPEG)
sensor.set_framesize(sensor.WQXGA2)

还是不行，内存不够吧

使用Wifi传输的时候 就会出现这个问题，请问该怎样解决

@kidswong999 删掉compressed()之后 图片就成这样了

这样也没办法用啊

固件版本4.4.2，OpenMV4 H7 Plus，运行没问题。
