Hey, i just got the data cable and am sort of a NOOB and the BitPim scene. but im running Bitpim 7.18 and have the LG 6000. When i trasnfer a JPG from my HD to my fones "image" area it automatically converts that JPG to a BMP for some ungodly reason. At 1st i thought it was the out of dated BitPim so i updated it to 7.23....same ×××× thing happed! If anyone can give me sum help or a tip or maybe a reason to why its doing that, please help out....thanks a bunch

bitpim has always done that

I don't know about the camera phones , picture output

but LG phones brew systems images are in bitmap

always have been as far as I know

The bitpim documentation says they do it for compatibility. The phone seems to support JPEG, but it seems to cause problems when they upload a JPEG. So they use BMP instead. They even had some info on how to overide that if you want to risk it anyway.

your 6100 is a camera phone

my 4500 does not support jpg format

only bmp format

and works best with pictures that are 16 bit or 8 bit color data

24 bit color data cause a buffer overflow and memory loss

themopedwhiz, I've read in other threads you mentioning this... how do you convert 24 bpp .BMP images to 8 bpp without quality loss? Photoshop goes down to 16 and XP Paint will do 8, however the image quality is horrible. Would you say then that 16 bpp is a good rule of thumb?

the phone works best at 16 bit color data

24 bit color data is wasted, the extra color data CAN NOT be displayed on the phone, the dispay is 16 bit

24 bit data causes the memory overflow and scroll shut down

yes 8 bit data is lower grade [ not as many color shading options ]

the trick to 8 bit or 16 bit color reduction ,is to reduce/optimize in stages, NOT in one shot

from 32 reduce to 24, then reduce to 16, then reduce to 8 bit, and save the picture

reduce the color data on the full size picture , BEFORE you crop and shrink the image.. NOT after you shrink it

this will greatly improve the quality of the final image

Excellent tip, thanks!

Maybe you can help me with an issue I have with BitPim. I was running 0.7.23 before today and uploading walls (yes, 24 bit .JPG's) to a VX6000. Any image now just shows up blank, even after working in Photoshop to reduce the images down to 16 bit and in size obviously.

Also, I can't remove any of the other images that were in the 'My Media' folder via either BitPim nor directly from the handset; a restart just brings them back again.

Sorry for the "n00bishness" -- I'm a Moto guy, but I'm doing this for a special lady friend. Thanks!

use bitpim

look in the phone file system tree for a file called

'brewimagemap' and delete it

then reboot the phone

do NOT use bitpim to delete the wallpapers

when you delete them in the wallpaper menu of bitpim

the file names are removed not the files, bitpim then writes an incorrect data format into the phone system

to remove unwanted wallpapers delete at the phone

this is well documented an listed 'BUG' / problem

Actually, with a little experimentation, I deleted all three "image.map" files, rebooted the phone, deleted the images from the handset, rebooted again (to be safe), and then re-sent each image back on to the phone one-by-one... sounds redundant, but it worked.

you fixed it..

now your fine, just remember to delet at the phone

then hook the phone to the computer

get/read the phone data , then add the new images

then send/ write the new data

Posted by: NineToez

Yup, all better now. Thanks for the tips and replies themopedwhiz, and I hope all this might have helped out others that have bumped into something similar.
