以下是測試通過的,至于GIMP方式,我沒有實驗成功。
1: 打開mat的inspector視圖,比較重要的是mBuffer, mWidth, mHeight

2:
In
MAT
for related Bitmap
object right click mBuffer
field and select "Copy" -> "Save Value To File", name the file with an .rgba
extension.
You need to note bitmap width and height from
mWidth
and mHeight
fields, which you can see in Bitmap object.
Having
ImageMagick
command line tools installed (for Ubuntu apt-get install imagemagick
), you issue convert
command with the following parameters. convert -size 'width'x'height' -depth 8 filename.rgba filename.png
For example
convert -size 680x1209 -depth 8 phone_decor.rgba phone_decor.png
