Hello,

I have been trying to work with the raster inset in order to create
icons and labels.  I must be doing something wrong because grey lines
always surround my rasters.  It's kind of annoying.  

My program code is as follows:
  

      do {
	if((temp_book = bs_BookData(self->bookshelf)) != NULL)
	  {
	    temp_info = book_GetInfo(temp_book);

	    book_width = (float)temp_info->size / ((float)self->min_size /
(float)MIN_BOOK) ;
	    book_height = 60;

	    if(book_width > MAX_BOOK)
	      book_width = MAX_BOOK;

	    if(strcmp(temp_info->picloc,"") && temp_info->pic==NULL)
	      {
		temp_info->pic = raster_New();
		temp_info->picview = rasterview_New();

		rasterview_SetDataObject(temp_info->picview, 
				            temp_info->pic);

		fp = fopen(temp_info->picloc, "r");
		raster_Read(temp_info->pic, fp, 1);
		fclose(fp);
		
	      }

	    if(temp_info->pic != NULL)
	      {
		RasterRect.width = raster_GetWidth(temp_info->pic);
		RasterRect.height = raster_GetHeight(temp_info->pic);
		if(RasterRect.width > book_width)
		  book_width = RasterRect.width;
		else
		  RasterRect.width = book_width;

		book_height = RasterRect.height + 4;

		RasterRect.left = position;
		RasterRect.top = baseline - RasterRect.height - 2;
		
		rasterview_InsertView(temp_info->picview, self,  &RasterRect);
		rasterview_AutoCenter(temp_info->picview);
		rasterview_FullUpdate(temp_info->picview, view_FullRedraw, 0, 0, 50, 50);
	      }

not be displayed.]	

You can see the problem if you click on the raster above and drag the
mouse to create a region.  Then click in the text and the frame will
change to a grey shade.

I was wondering if anyone has done work with the raster object and
figured out what to do about this slight annoyance.

				Thanks, (in advance)
