使用精确规格将JPG转换为BMP

问题描述

我正在尝试更改AMLogic设备的显示启动飞溅（使用此工具：https://github.com/steeve/aml-imgpack）。我有一个JPG，可以根据设备需要将其转换为BMP（例如https://unsplash.com/photos/SnXIF8_2oPw），但是颜色完全错误，图像以“线”分隔，从左到右的某些部分在右边（有点喜欢重复图像，但不完全是这样。

原始图像具有以下属性：

我尝试使用以下方法进行转换：

$ mogrify -format bmp ../new_bootup.jpg
$ mogrify -format bmp -type TrueColor ../new_bootup.jpg
$ mogrify -format bmp -define bmp:subtype=RGB565 ../new_bootup.jpg

，但是图像无法正确显示。问题是：我应该使用哪个标志（或我应该使用哪个工具）来尽可能地重现原始属性？
