    Hello,
    when you call RenderDocument() an image that is too small to cover the rendering, nothing is rendered _but_ RAY_OK is returned.

    like:

    RenderData* rdata = doc->GetActiveRenderData();
    BaseContainer _rdata = rdata->GetData();

    AutoAlloc<BaseBitmap> bmp;
    bmp->Init(_rdata.GetReal(RDATA_XRES) -1, _rdata.GetReal(RDATA_YRES) -1 ) != IMAGE_OK)

    if (RenderDocument(doc, _rdata, NULL, NULL, bmp, RENDERFLAG_SHOWERRORS, NULL) != RAY_OK)
    {
        return FALSE; // this will not be reached
    }

    Is this by design? I'd guess that when no rendering took place the return value would be different from RAY_OK.

    Cheers.
