hey,
i too facing the problem of memory leak while
displaying gif images using OMRaster . I observed that
OMRaster is using "BufferedImageReader" in which the
image is read as type "TYPE_INT_ARGB" . When i
replaced the type with "TYPE_BYTE_INDEXED" in place of
"TYPE_INT_ARGB" it is observed "no memory leak" . And
i could able to display gif images without memory leak
.
Now i would like to know is this the problem with
OPENMAP or is it the java method unable to handle the
image ?
I would like the users who posted comments on
"OMRaster" to test this and pass on your comments ,
pl.
Thx and Regards
