Hello!
XXL at http://atarionline.p...&page=1#Item_11wrote,that he's searching for GFX-man, who can draw GFX for 3rd mode of Basic (8 mode Antic). So, I wrote early beta version for do it.
Handling:
1,2,3,0 - color number
L - load data (960 bytes)
S - save data (960 bytes)
D - drawing/clearing picture
Draw with joystick. Load and save data with full path (for example: D:TEST.SG3).
One more - no DOS exit and no error detect in this beta, but fully functional for this time.
Some info about SG3 (Standard Graphics 3) format:
- four colours
- 40x24 resolution
- no additionalinformation
- only 960 bytes long
In future I'm planning add AG3 (Additional Graphics 3) format:
- add colour options on the end of file (4 bytes)
- maybe add some bytes for info/author for future use (max 800 bytes) - for examples to presentation
- 964 (or 964+800 bytes max) long.

Best regards,
Sikor

New format AG3 description:

Extended with additional data format SG3. Description indicates the additional elements (described in the order ).

* Information about the color settings at the end of the file ( 4 bytes)
* Differentiator file ( 1 byte in the form of a mark ) :
** N - no further information
** S - short info
** I - info
** A - animation
** F - future applications
* Length of 245 (or 245 + additional ) bytes

Highlights :
* N - indicates the absence of additional information , it ends a file, the file length 245 bytes
* S - a short info, 40 - byte text information at the end of the file, the file length of 285 bytes
* I - info , information Descriptive divided into blocks :
** 240 bytes of data
** 4 bytes in order of color registers 708, 709, 710 and 712
** Discriminant I - 1 byte
** 40 bytes short info ( the same as the differentiator S)
** 1 byte indicating the amount of 120 byte blocks description (1 to 3 )
** Additional descriptions blocks - 120 , 240 or 360 bytes
In total file length will be 406, 526 or 646 bytes
* A - animation ( in preparation)
* F - " future" , the extras are not specified (probably the image width , height , others - in preparation)

== What are the differentiators ? ==

The purpose of this format is to use the image boxes in a custom way. With the description of the work included in the file "on compo " may incorporate a description, and record them at the end of the data does not affect the display . You can use them to encode additional options (for example, the number of frames in the animation and switching time - may well be one slideshow ).

Format *.AG3 will be available from next public beta version.
