Hi,

I have a navigation system that uses ".pim" images and logo's. Is
there a program that will open and save a image (jpeg) as a .pim so I
can customize the GUI of the system?
I have supplied one of the .pim images at
http://jasonhilton.us/d1/backgrounds/AURORA.PIM

Thanks,
Jason

Can you tell us what application it comes from ?

These are likely things I've found.
PIM = PixMaker Project File
PIM = Ultimate Draw : Pascal text mode image file

From looking at the sample file, it appears to be a bit image with no
compression, or maybe it is character and attribute - 04h turns up a
lot.
Its header looks simple.

If that really is what the file contains, then it should be pretty
easy to write a routine that loads a JPG and outputs something in that
format.
- of course that is a fallback solution

I missed something there
- too busy grabbing the image and looking at it to think.

When you say 'navigation system' is this something that runs on a standard PC ?

What do the 'images' look like, are they monochrome or colour
- are they a bit 'blocky'

Does 500 x 240 mean anything to you ?
- the 16 byte header contains 16, 500, 240 
- which suggests 16 bit pixels 
- eg: 2 x 500 x 240 = 240,000 + header = file size



Is there any chance that you can grab a screen shot so we can see what
AURORA.PIM looks like

Hi, thanks for the reply.

The Navigation system is a Pioneer AVIC-D1 that is in my car.
The images are in color and a little blocky.
I think the image is 500x240x16 as well.
I took a picture of it here: www.jasonhilton.us/d1/backgrounds/AURORA.jpg

Using what you said:

- the 16 byte header contains 16, 500, 240 
- which suggests 16 bit pixels 
- eg: 2 x 500 x 240 = 240,000 + header = file size

I was able to open the image in photoshop using a RAW format, but the
image apears in gray only. Any ideas?

I've been playing with reading the raw pixels

At its simplest I get a reddish image similar to your monochrome image.

I guess the Photoshop figures that the data must be 16 bits, but
chooses monochrome as it does not recognize the color format.

I'm not sure what to make of - it looks like a blueish bit of crumpled paper:

I've tried breaking the 16 bits into 3 RGB colours
- but the results are not that good

It must be some custom implementation.

After a flash of inspiration, I realized that I had made a coding error.

I've got something that looks like your B&W image, but is mostly green and blue.
