I have +- 500 .bmp's that I would like to convert to .png's. It would be especially nice if the color white (#FFFFFF) of the original BMP's could be converted to transparent in the .png's.
PNG-8 is enough since the .bmp's are 16-colors.
I would prefer a command-line tool that I can put in a batch file, but any would be useful. Do you know of such a tool?
edit: The OS I use most is Windows 7 x64, but I also have Cygwin and various linuxes available
if you want to run it as a bash script for batch conversion in a whole folder full of files: for file in *.png ; do convert "${file}" -transparent '#ffcc66' "batch/${file}" ; done – Sameer Shemna – 2014-10-21T10:09:55.630
2That definitly seems promising.
conver -transparent white source.bmp dest.png
does exactly what I want, however only mogrify supports multiple files and it only has-transparent-color
which doesn't really work. Looking further – dtech – 2011-09-26T19:35:36.123Ultimately I just used a script with a loop. For those, interested, effictive code was
convert -transparent white $f ${f%bmp}png

@woliveirajr it was a bash shell, other shells should allow simalar constructs – dtech – 2011-09-29T12:24:57.517
