1New driveropts= option "tattoofile=". Use together with -checkdrive
2to write an image of the right size to disk.

4	DiskT@2 hints:
5
6	In order to have "DISKTATTOO" listed in the "Driver flags",
7	the disk currently inserted must be usable for the DiskT@2 feature.
8	This means that there needs to be enough space on it.
9
10	You need an B&W image with 3744 pixels per line
11
12	Best start with a 3744 x 320 pixel image.
13	The correct size may be retrieved with
14		cdrecord driveropts=tattooinfo -checkdrive
15
16	To get RAW image data:
17
18	-	Take 'xv' and save the image in PBM/PGM/PPM (raw) mode
19
20	-	use a binary aware (must support unlimited linelength)
21		editor such as 'ved' and remove the header lines.
22		These lines look like:
23
24		P5
25		# CREATOR: XV Version 3.10a  Rev: 12/29/94 (PNG patch 1.2)
26		# CREATOR: XV Version 3.10a  Rev: 12/29/94 (PNG patch 1.2)
27		3744 144
28		255
29
30		Now you should have (in case of the file above) a file that
31		has exactly 539136 Bytes.
32
33	-	Note that the tattoo image must be left to right flipped
34		(a mirror image).

36From a hint from "E. Robert Bogusta" <rob23@tmr.com>:
37
38Take an image, and do:
39
40  djpeg myface.jpg | ppmtopgm | pnmflip -lr |
41    pnmscale -xsi 3744 -ysi 320 | sed '1,/255/d' >myface.tattoo
42
43So:
44  djpeg extracts ppm from a jpeg. Use your favorite other way of getting
45this far is you wish.
46
47  ppmtopgm changes color to grey scale
48
49  pnmflip -lr flips left to right, the small image is faster
50
51  pnmscale makes it 3644x320 regardless of starting size. This may make it
52look really odd on the CD if it doesn't start off the right size. More on
53this after I try it.
54
55  sed strips from the first line to the line containing 255, which is the
56last header line.
57
58Note that it would be better to use the actual height of the applicable image instead
59of the maximum value of 320 and it would be even more correct to create an
60image that has the right width/height ratio for the target on CD in order
61get an undistorted view of the image on CD.

63For best visibility, use black text on light background.
