if i have a valid image in an imageObj object:
- int imageObj.getWidth() returns the expected value
- int imageObj.getHeight() returns the expected value
- void imageObj.save(String, null) successfully writes the image to a file
- byte[] imageObj.getBytes() successfully returns a byte array (whose length
matches the size of the file above), containing the proper contents of the
image (i can subsequently dump it to a file and verify).
however:
- int imageObj.getSize() always returns 0
this turns out to not be a big deal. at first i thought i would have to
query
the size with getSize(), then allocate a byte[] of the appropriate size,
then
populate the byte[] with getBytes().
however, it is sufficient to just write code like:
byte[] bytes = img.getBytes();
if img is the imageObj containing the image. it's not necessary to directly
query the size, and if i really want to know it, bytes.length will return
the
proper value.
nevertheless, if i'm properly guessing the intention of imageObj.getSize()
[maybe i'm wrong], this seems like a bug to me.
i do notice the following in mapscript/doc/mapscript.txt within the
mapserver-5.0.0 distribution:
--- begin ---
imageObj Attributes
-------------------
<...>
size : int
I don't see where this is used. Anyone? --SG
<...>
imageObj Methods
----------------
[getSize() is not listed here]
--- end ---
so maybe it's just deprecated.
