SYNOPSIS¶
sna2img.py

DESCRIPTION¶
sna2img.py
converts a Spectrum screenshot or other graphic data into a PNG
file. INPUT may be a binary (raw memory) file, a SCR file, a skool file, or a
SNA, SZX or Z80 snapshot.
OPTIONS¶
-b, --bfix | When INPUT is a skool file, parse it in @bfix mode. |
-B, --binary | Read INPUT as a binary (raw memory) file. |
- -e, –expand MACRO
- Expand a #FONT, #SCR, #UDG or #UDGARRAY macro. The ‘#’ prefix may be omitted, and any filename parameter is ignored.
- -f, –flip N
- Flip the image horizontally (N=1), vertically (N=2), or both (N=3).
-i, --invert | Invert video and reset the FLASH bit for cells that are flashing. |
- -m, –move src,size,dest
- Move a block of bytes of the given size from ‘src’ to ‘dest’. This option may be used multiple times. ‘src’, ‘size’ and ‘dest’ must each be a decimal number, or a hexadecimal number prefixed by ‘0x’.
-n, --no-animation | |
Do not animate flashing cells. |
- -o, –origin X,Y
- Top-left crop the image at tile coordinates (X,Y).
- -O, –org ORG
- Set the origin address of a binary file. This option implies
--binary
. The default origin address is 65536 minus the length of the file. ORG must be a decimal number, or a hexadecimal number prefixed by ‘0x’. - -p, –poke a[-b[-c]],[^+]v
- POKE N,v for N in {a, a+c, a+2c…, b}. Prefix ‘v’ with ‘^’ to perform an XOR operation, or ‘+’ to perform an ADD operation. This option may be used multiple times. ‘a’, ‘b’, ‘c’ and ‘v’ must each be a decimal number, or a hexadecimal number prefixed by ‘0x’.
- -r, –rotate N
- Rotate the image 90*N degrees clockwise.
- -s, –scale SCALE
- Set the scale of the image (default=1).
- -S, –size WxH
- Crop the image to this width and height (in tiles).
