problem with backdrops

[kyle3210]

i have been searching everywhere for a guide explaining how to put backdrops on my video ipod, and i cant find one

i know that you have to convert them to a different format and resize them but im not sure what format and how big they have to be,

any help would be appreciated

thats the one im trying to use

i would just convert it for you but i cant attach it to this post b/c of its size.

go to this website and dowload the free trial, i'd get the abc.exe

http://www.batchconverter.com/download.shtml

after you have that installed, launch it, then press Ctrl+B to enter batch mode.  when your in batch mode, check the box that says "use advanced options."  then click the "options" button just to the right of that.  in the options check the "resize" box and then put 320 for the new width and 240 for the new height.  you also need to uncheck the "preserve aspect ration" box.  then click ok to save your settings.  now go to "output format" and choose .bmp at the very top of the drop down.  now just add your picture and click start.

hmm i have one more question, lol

so i made a root folder on my ipod called backdrops and put the 320x240 bmp file in it, unplugged my ipod, went to the file on my ipod, selected "set as backdrop" and i got a message saying "backdrop failed". i would have put it in the .rockbox folder under backdrops but then i dont know how to access it on my ipod

can anyone tell me what i did wrong??

all help appreciated

Is the bitmap saved in 24-bit color?

[kyle3210]

yea it is

[Llorean]

You have an iPod video, with a 24-bit 320x240 (exactly!) bitmap, and it's saying that it's failing?

Can you post the bitmap somewhere?

[kyle3210]

type of file:bitmap image

Location:g:/backdrop

Size: 48.9 KB (50,111 bytes)

Size on Disk:64.0 KB (65,536 bytes)

bit depth: 24

width: 320 pixels

height: 240 pixels

horizontal resolution: 71 dpi

vertical resolution: 71 dpi

frame count: 1





i dont know why it isnt working, im thinking that i have to save it in the .rockbox folder under backdrops but then i dont know how to access it...

[Llorean]

A) Can you post the bitmap somewhere?
B) The filesize doesn't seem to match what it says the resolution is (assuming my math isn't wrong).

[kyle3210]

ok i used the program listed above and everything is working fine

thanks for helping me out
