png2inr - convert a PNG image into an Inrimage image.
png2inr
[png-file]
[-i|output]
[-8]
[-noalpha]
[-hdr=%d]
[-D]
png2inr
Any PNG formats are supported : that's meaning a valid Inrimage image is created.
However, Inrimage displayers do not displaying correctly some format, for example,
PALETTE for image bit size lesser than 8 are not correctly displayed (limitation of
Inrimage displayer, not Inrimage image format). Using the -8 option solves most of
problems encountered.
Some PNG formats can use an alpha channel; they are converted as vector image:
- GRAY and ALPHA are converted into a 2-component image (-v 2),
- RGB and ALPHA are converted into a 4-component image (-v 4).
xvis does not handle alpha channel (but gvis does). One can elimate the alpha
channel using the -noalpha option. For Inrimage user: you can keep the channel alpha
and filter using extg command. Example with png2inr installed as plugin:
$ extg -v 3 image.png | xvis
Finally, png2inr can display information about a PNG image (option -i).
- -i
- just display info on png file
- -8
- convert pixel/component values to 8 bits. Works for any bitcoding (1,2,4,16).
- -noalpha
- Remove the alpha channel (if exist)
- -hdr=
- to increase the header file size if needed
- -D
- print Inrimage and program traces
