I have this script that should make a bit map file of an image, but it was made for Photoshop.

How do I do the same thing but with GIMP?


If any of you are familliar with an EEPROM...
I want to make a bit map that the pixels can be read horizontally (lowers address values A0-A6).
The lines would be vertical and would be addressed by the higher values (A7-A13)

I would really want a suitable 200x150 image to be converted to above format.
The image I linked is an example image but its 100x75.
I have a video link if you see the guy do the stuff in Adobe to know what exactly I am talking about

Why would you post a bin file? Why not just screenshot the bin when you have it open on your end, and then convert it to jpg or png?

[twisted67]

Sorry.
Here is the png not bin. I grabbed the wrong link.

Image/Mode/Indexed/Black & White 1-bit?

[twisted67]

Hm.

How do i get the raw pixel data? And write it to a new file? (BIN)
I think thats what I am trying to ask.

I want to load the picture into an EEPROM...no file information should be saved.

The png file needs to be in indexed mode and maybe only 64 colours Use Image -> Mode -> Indexed and set the number of colours



This using linux. I have no idea how PIL is installed in Windows

However, with file and script in a folder, edit the script to suit file names / image size. Run the script and it outputs the .bin file.



best of luck

Thanks. I figured out that I just need to install Python to run the script.

For some reason I thought Photoshop came with the ability to do what Ben Eater did. Kinda stupid.

In case OP ever comes back.

Looking on the eater.net/ site the conversion to Indexed mode uses a color palette "64-color.act" Not a format that Gimp uses. Not difficult to manually re-write to .gpl format. (attached) Unzip then 64-color.gpl goes in C:\Users\"yourname"\AppData\Roaming\GIMP\2.10\palettes

Conversion Image -> Mode -> Indexed Set the palette. Set one of the dither modes. Export as a png. Example:
