c++ - How do I convert an RGB byte[] slice to an image.Image in go? -


a c++ application running in process passes in char[] array of three-byte pixels (red, green, blue) go program. i've reconstructed in go byte[] slice using cgo, i'm unsure how convert image. can pass width or height well, if needed (i imagine be).

i'm aware of image.rgba type, documentation seems imply aren't single-byte-per-color, , assumes there alpha channel, simplistic bitmap not have. converting 3 byte values have works image.rgba solution? if so, how should that?

alternatively, conversion in c/c++ before sending values format go recognizes (jpeg, gif, png). either way works uses, don't know how approach either.

the image package based on interfaces. define new type those methods.

your type's colormodel return color.rgbamodel, bounds - rectangle's borders, , at - color @ (x, y) can compute if know image's dimensions.

i have large set of data points. try plot them boxplot, of outliers exact same value , represented on line beside each other. found how set horizontal distance between outliers in gnuplot boxplot , doesn't much, apparently not possible. is possible group outliers together, print 1 point , print number in brackets beside indicate how many points there are? think make more readable in graph. for information, have 3 boxplots 1 x value , times 6 in 1 graph. using gnuplot 5 , played around pointsize, doesn't reduce distance anymore. hope can help! edit: set terminal pdf set output 'dat.pdf' file0 = 'dat1.dat' file1 = 'dat2.dat' file2 = 'dat3.dat' set pointsize 0.2 set notitle set xlabel 'x' set ylabel 'y' header = system('head -1 '.file0); n = words(header) set xtics ('' 1) set [i=1:n] xtics add (word(header, i) i) set style data boxplot plot file0 using (1-0.25):1:(0.2) boxplot lw 2 lc rgb '#8b0000...

bash - Performing variable substitution in a string -

i have string contains use of variable, , i'd substitute variable's value string. right best have is #!/bin/bash foo='$name; echo bar' name="the name" expanded="$(eval echo "$foo")" echo "$expanded" which has obvious defects: prints the name bar while i'd print the name; echo bar instead of eval can bash's regex matching bash's string replacement: foo='$name; echo bar' name="the name" [[ "$foo" =~ \$([[:alnum:]]+) ]] && s="${!bash_rematch[1]}" && expanded="${foo/\$${bash_rematch[1]}/$s}" echo "$expanded" name; echo bar
