Hello.

Hi,
I've written a script to search for an Oracle ORA- error on a log file, print that line and the .trc file associated with it as well as the dateline of when I assumed the error occured. In most it is the first dateline previous to the error.
Unfortunately, this is not a fool proof script.... (2 Replies)

Hey,
I added an animation switch on the search results page; so by default the thread previews are off, but if you want to look at them, just click on the green button and the thread previews will turn on (and back off).

Today I changed the forum mysql database to permit 2 letter searches:
ft_min_word_len=2
I rebuilt the mysql search indexes as well.
Then, I added a "quick search bar" at the top of each page.
I have tested this and two letter searches are working; but it's not perfect,... (1 Reply)

ppmtosixel
ppmtosixel(1) General Commands Manual ppmtosixel(1)NAME
ppmtosixel - convert a portable pixmap into DEC sixel format
SYNOPSIS
ppmtosixel [-raw] [-margin] [ppmfile]
DESCRIPTION
Reads a portable pixmap as input. Produces sixel commands (SIX) as output. The output is formatted for color printing, e.g. for a DEC
LJ250 color inkjet printer.
If RGB values from the PPM file do not have maxval=100, the RGB values are rescaled. A printer control header and a color assignment table
begin the SIX file. Image data is written in a compressed format by default. A printer control footer ends the image file.
OPTIONS -raw If specified, each pixel will be explicitly described in the image file. If -raw is not specified, output will default to com-
pressed format in which identical adjacent pixels are replaced by "repeat pixel" commands. A raw file is often an order of magni-
tude larger than a compressed file and prints much slower.
-margin
If -margin is not specified, the image will be start at the left margin (of the window, paper, or whatever). If -margin is speci-
fied, a 1.5 inch left margin will offset the image.
PRINTING
Generally, sixel files must reach the printer unfiltered. Use the lpr -x option or cat filename > /dev/tty0?.
BUGS
Upon rescaling, truncation of the least significant bits of RGB values may result in poor color conversion. If the original PPM maxval was
greater than 100, rescaling also reduces the image depth. While the actual RGB values from the ppm file are more or less retained, the
color palette of the LJ250 may not match the colors on your screen. This seems to be a printer limitation.
