WMS: image/wbmp should be image/vnd.wap.wbmp

[bartvde]

currently in a WMS GetCapabilities response Mapserver advertizes image/wbmp, this should however be image/vnd.wap.wbmp according to:

You're right; image/vnd.wap.wbmp seems to be the definitive way to define a wbmp MIME type. I'm not sure of the history of image/wbmp in MapServer or how it got there, however.

I also wonder on how much image/wbmp is used. Would be interesting to hear other dev's thoughts here.

We probably didn't do much research before deciding to go with image/wbmp ... we probably just assumed that it was the right MIME type to use based on others (image/gif, image/jpeg, etc.).

I don't know how much WBMP is used today, or if at all via WMS, but it's there and has been used in the past so I would not remove it unless we really have to. I'd suggest we file a ticket about switching from image/wbmp to image/vnd.wap.wbmp, with a pointer to the authoritative resource that defines image/vnd.wap.wbmp, and then we could make the change in MapServer. Ideally we'd make the change only in 5.2, but if we really have to we could backport to 5.0.x.

This occurs in 3 files:

$ clear;grep -i "image/wbmp" *.[ch] mapoutput.c: format->mimetype = strdup("image/wbmp"); mapwms.c: mimetype = strdup("image/wbmp");

mapwmslayer.c:

strcasecmp(papszTok[i], "image/wbmp")

I'll make the necessary changes.

Sorry, here's comment:2 with better formatting:

$ clear;grep -i "image/wbmp" *.[ch]
mapoutput.c:        format->mimetype = strdup("image/wbmp");
mapwms.c:                         mimetype = strdup("image/wbmp");
mapwmslayer.c:                || strcasecmp(papszTok[i], "image/wbmp")

Based on this (i.e. there were GD driver specific WBMP defs which I did not touch),

• mapserver changes made in r6969
• HISTORY.txt updated
• msautotest changed made in r6970
