i found width , height of png image.
but when m calling addimagesnip() after shown message "out of memory".
while select jpg file , found width , height of jpg file after m calling addimagesnip() function image inserted pdf successfully.
why fuction not working png format ?
can 1 tell me how set value of pdeimagematrix , parameter passing pdeimagecreate() function png image file......?
pdeimage volatile pdeimage = null;
pdeimageattrs pdeimageattrs;
pdecolorspace pdecolorspace;
asfixedmatrix imagematrix;

pdeimageattrs.width = width;
pdeimageattrs.height = height;
pdeimageattrs.bitspercomponent = 8;
imagematrix.a = asint16tofixed(width);
imagematrix.d = asint16tofixed(height);
imagematrix.b = imagematrix.c = fixedzero;
imagematrix.h = fixedzero;
imagematrix.v = fixedzero;
pdecolorspace = pdecolorspacecreatefromname(asatomfromstring("devicergb"));
pdefilterarray filterarray;
pdefilterspec filterspec;
memset (&filterspec, 0, sizeof (pdefilterspec));
filterspec.name = asatomfromstring ("dctdecode");//flatedecode //dctdecode
filterarray.numfilters = 1;
filterarray.spec[0] = filterspec;
astfilepos size = asfilegeteof(asfile);
during
pdeimage = pdeimagecreate (&pdeimageattrs, sizeof(pdeimageattrs), &imagematrix,
kpdeimageencodeddata , pdecolorspace, null,&filterarray,
asstm, null, asfilegeteof(asfile));
handler
ierrorcode = asgetexceptionerrorcode();
end_handler
if (0 == ierrorcode)
{
pdpage pdpage;
pdecontent pdecontent;
pddoc doc=null;
if(!createpdf)
{
avdoc avdoc = avappgetactivedoc();
doc = avdocgetpddoc(avdoc);
pdpage = pddocacquirepage (doc, 0);
}
else
{
doc=pddoccreate();
asfixedrect mediabox = {asint32tofixed(0), asint32tofixed(0), asint32tofixed(width), asint32tofixed(height)};

}
if(pdpage == null)
return null;

}

end_handler

asbool sucess = pdpagesetpdecontent (pdpage, gextensionid);
pdpagereleasepdecontent (pdpage, gextensionid);
this code correct jpg not working png.
can 1 tell me why not working png ?
