2431.0. "u: CRASH IN IMG$SHRLIB" by FRSMS::dhcp-186-128-62.coo.dec.com::noethen () Tue Jan 28 1997 21:24

Hi,

we have got a problem in one of our applications which is used to render an image. Using the DCL OCNVERT command
the following behaviour can be watched:

$CONVERT/DOCUMENT 1.DDIF/FORMAT=DDIF 1.TIFF/FORMAT=TIFF
%ISL-F-INVCODTYP, invalid code type encountered during decompression.

In out sources we are trying to decompress the frame using

DecompressFID = ImgDecompressFrame(  InputFID,
					ImgM_AutoDeallocate,
					0);

This results in:

%ISL-F-INVCODTYP, invalid code type encountered during decompression.
Break on unhandled exeption preceding SHARE$IMG$SHRLIB+1039796.

Some of the customers images are rendered, some not. The only difference between these images is
the IDU_BIT_ORDER.
...
}
 IMG_CONTENT
 {
   ...
   IDU_BIT_ORDER MSBIT_FIRST ! Integer = 2 instead of LSBIT_FIRST


$anal/image sys$share:img$shrlib.exe

		id: DW V1.2-3941206


This is a high priority problem. Does somebody know how we can get a solution for that? Is this the conference
to address this problem? Who is servicing that staff? ...

Thanks in advance
