The existence of this utility takes some explaining. Encouraged by the availability of the free BMP2PNG program for automating conversion of bitmaps to PNGs (just search Google), I naturally searched for something called "BMP2JPG" when I needed it. Such a thing exists: more than once, in fact, but the first one you find on Google is being sold for $99 a copy. Now there's nothing wrong with selling such a utility, but $99 did seem a bit steep to me (I would have bought it had it been only $19, since it would have saved me a few hours). The next thing I ran into was a program by Tomoaki Misaki, which with or without his consent had got out onto the web at large, and I downloaded it to find that it did the job! However it was last updated in November 1994 and this lead to some undesirable features:
- It doesn't recognise long filenames (i.e. those more than 8.3 characters);
- It always works relative to the directory it is in, so if you place it in your c:\windows directory you'll have to use absolute paths almost all the time;
- Those paths can't have any directory names that are longer than 8 characters either;
- It doesn't recognise wildcards, so you have to do every file individually.
Therefore: bmp3jpg was written as a wrapper program to call BMP2JPG in such a way that everything is fixed with duct-tape and wildcards work as I wanted them to. I also took the opportunity to add a "delete originals after encoding" commandline switch and a couple of others that rescale the image before turning it into a JPG, should you want thumbnails or suchlike. All other switches are passed through to BMP2JPG and the help screen, which you get by running the program with no arguments, is a team effort between the two programs. The 'scaling' feature was a slightly wicked thing to add on my part, since I'd copied the idea from the web page of the people selling the $99 version...
