Hi friends

I'm trying to convert a bmp to BMP, with the explicit requirement, that the file must be a type BMP3.

You see, the Tablet bootloader (NAND.a) can only display special type BMP's, but imagemagick resulting the output really same still the tablet charging animation unable to show the colour change on screen. I think there might be some automatic conversion done which i am not aware of please help

i even tried to convert it using GIMP but the result is always same Tablet cant display the modified colour here

original can work without any problem

How about:

Code: Select all

magick bat10-og.png -type palette -compress None bmp3:out.bmp

i can test please give me few minutes to post result

bad

Code: Select all

magick bat10-og.png -type palette -compress None bmp3:out.bmp

same result TAB unable to display the edited file ....please excuse my english

here is the original archive if interested ..which need to change the colour of green to blue

https://www.sendspace.com/file/m0xfah

My result is BMP3, with palette, and no compression. What else does it need to be?

i guess you are not getting me my i want to change the colour of battery animation in my tablet but only original files work if i replace anything or modifi anything like above i modified colour it doesnt show that it shows wired animation or picture which is hardly recognizable so i want to know how original files work but when modified it shows unrecognizable colour or like blurred there must be some more settings to picture

can we set Blue COLOUr with instead of green within ImageMagic? and also convert the required format?

right now what i am doing is using Gimp or Inkscape for colour change than exporting the original image from BMP TO PNG than converting PNG to BMP with imageMagick to fit into the parameters required by TABLET

please help me out i have tried almost everything what i know from WWW

To change color, try -modulate.

Code: Select all

convert bat10-og.png -modulate 100,100,133 -type palette -compress none BMP3:result.bmp

See https://imagemagick.org/Usage/color_mods/#color_mods

Changing the colour is easy. But we don't know what format is needed.

oh bro both the formats are BMP clearly

1=see First post original with green colour with information which works in the ANDROID TABLET

2=see first post Modified by me in gimp WITH BLUE colour with information which does not work in android Tablet (i want this colour in battery icon and also want it to work in TABLET)

colour changed perfectly by your command thanks sir (i learned one thing today) but problem remains same when i write it to the TABLET ANIMATION it unable to show the change in place of our modification it shows weird,blurred thing which is beyond recognition

and i noticed original icon is 118kb after command it become 89kb does it make any difference

I do not understand your "TABLET ANIMATION". What is that? If you are saying that the results above do not display properly in some other software, then provide an example image that does and we can try to see what is different.

example original images which can work in tablet animation is below i already provided and in the first post i already show the both details original image and modified image with details of each

https://www.sendspace.com/file/m0xfah

or

https://github.com/pcduino/a20-kernel/t ... fs/os_show

you can take any image from the link

..
bat0.bmp
bat1.bmp
bat10.bmp
bat2.bmp
bat3.bmp
bat4.bmp
bat5.bmp
bat6.bmp
bat7.bmp
bat9.bmp

after any modification of any of the above image can not display properly in TABLET ANIMATION(the animation any phone show while power off when charging battery) i hope its clear now

Your input is not 9-bit palette but truecolor (24-bit) BMP3. So try this

Code: Select all

convert bat10.bmp -modulate 100,100,133 -compress none BMP3:result.bmp

When I compare the Imagemagick verbose information, it appears to similar.

EXIFTOOL says your image is bit depth 32, but there is no alpha channel. The above creates a bit depth of 24. So your file has bad meta data.

BMP3 does not formally support bit-depth of 32. Only BMP/BMP4 supports that properly.

So you can try using EXIFTOOL to edit the result of my first command to change the 24-bit bit depth to 32

See https://www.sno.phy.queensu.ca/~phil/exiftool/ and https://www.sno.phy.queensu.ca/~phil/ex ... l_pod.html

But according to https://www.sno.phy.queensu.ca/~phil/ex ... s/BMP.html, you cannot write over the BitDepth tag. So I am not sure what to tell you. Your file meta data is not accurate for BMP3.

what command i shoud use to write metadata?I tried

exiftool -tag=32 result.bmp
Warning: Tag 'tag' is not defined
Nothing to do.

exiftool -tag=32 -w result.bmp
No file specified

exiftool -w -tag=32 result.bmp
1 output files created

1kb file created by the name..... result.-tag=32 <=========what to do with that?

when i open this file in NotePad its shows

i also found a thread with a similar problem where IM was not preserving alpha but that was fixed long ago and in my case no alpha

http://www.imagemagick.org/discourse-se ... =1&t=28733

i guess we are near to the solution and you have got the correct nerve its a BitDepth problem i also think same

I do not know any tool that will change the BitDepth. The BMP format link I mentioned above says it is not changeable.
