-# Open source and universal binnary file format for mSLA/DLP (.odlp)
-
-This file format aims for simplicity and universal file format for low-end printers that can't take
-a ZIP + PNG slices approach due the incapacity of CPU to process such data schemes.
-
-## Implementation requesites
-
-- Open-source file format
-- Document the changes and revisions, as well the reserved table if any
-- Universal: the file and revisions should always be compatible with any firmware that take this file
-- No encrypted files: The data should be plain and easy to access
-- No property or changed variant of the file format should exists!
-- Machine follows sequential gcode commands
-
-## Printer firmware checks (can print this file?)
-
-1. Marker == "ODLPTiCo" - This is a double check if file is really a .odlp beside it extension, case sensitive compare.
-1. Compare machine resolution with file resoltuion.
-2. Can use ImageDataType? For example, if processor is unable to process PNG images, trigger an error and dont allow to continue.
-3. Parse gcode and check for problems, such as, print on a position out of printer Z range.
-
-## Printer firmware layer data adquisiton
-
-1. Machine firmware detects `M6054 i` gcode command.
-2. Goes to the layer definition table at the `i` index given by the `M6054` command.
-3. Gets the image address and jumps to it.
-4. Start to read and buffer the image to the LCD.
-5. Jump back to the resume position and continue to execute the gcode.
-
-**Note:** Printer only continue to execute the next gcode command after the image is displayed/buffered. 
-When using a sencond board to display the image, it must send a OK back in order to resume the gcode execution.
-
-## Software data adquisiton
-
-For slicers and other programs, data and per layer settings should be parsed from gcode.
-
-## In file optimizations
-
-1. When generating the file, layers that share the same image data, may reuse that data instead of duplicate the image. 
-This allow to spare a good amount of data when file contains multiple layers that share same image over and over, for example, functional parts.
-See example on file sample bellow at `[Layer 3]`.
-While this is optional and either way it must be valid to print, is highly recommended to hash the layers.

-Notes:
-1) Previews start address = file table size + header table size + custom table size
-2) Header dont need much information, everything can be parsed from gcode!
