06-23-2005, 14:46 johnbonds@hotmail.com Joined on 06-16-2003 Los Angeles, CA Posts 11 Can't load TIFJBIG file compressed I scan a new image and save it to a multipage TIF file using the following line pCodecs.Save(e.Image, LocalBatchFile, LEAD.Drawing.Imaging.ImageFormat.TifJbig, e.Image.PixelFormat, LEAD.Drawing.Imaging.Codecs.Codecs.SaveModifyConstants.Append) I then try to load that image into memory using the following: Dim pCodecs As New LEAD.Drawing.Imaging.Codecs.Codecs Dim pLEADBitmap As New LEAD.Drawing.Bitmap pCodecs.LoadCompressed = LEAD.Drawing.Imaging.Compression.Super pCodecs.Load(pLEADBitmap, LocalBatchFile, LEAD.Drawing.Imaging.PixelFormat.DontCare, vPageNum, 1) ctlImage.DisplayImage(pLEADBitmap) pLEADBitmap.Dispose() pCodecs.Dispose() When the image gets loaded into memory however, the JBIG .BITMAP size reports 18072 in debug mode. When I use CCITT Group 4, it's 15476. Now the actual file is smaller using JBIG which is nice. However my application's memory utilization jumps 8-10MB when the single page is loaded from the TIF file as TIFJBIG and I can't seem to figure out why this is happening. Could someone please explain? Another note... Even after I dispose of the LEADBitmap, the memory usage stays. Thanks    Report

I tried to check the same issue using your code, but I need to know the following: - What is the type of the ctlImage contro (in your code)? - What is the BPP of the result Tif JBIG image? - If you tried to save any another image (such as BMP image) to Tif JBIG format. Then try to load it. Do you get the same results?   However, I checked this issue using the following code, and the image is loaded successfully on the LEAD Picture Box control: =========================================  Dim codecs As New LEAD.Drawing.Imaging.Codecs.Codecs PictureBox1.LEADImage = LEAD.Drawing.Image.FromFile("c:\1.bmp")   codecs.Save(PictureBox1.LEADImage, "c:\test123.tif", LEAD.Drawing.Imaging.ImageFormat.TifJbig, LEAD.Drawing.Imaging.PixelFormat.Format24bppBgr, LEAD.Drawing.Imaging.Codecs.Codecs.SaveModifyConstants.Append)   codecs.LoadCompressed = LEAD.Drawing.Imaging.Compression.Super codecs.Load(PictureBox1.LEADImage, "c:\test123.tif", LEAD.Drawing.Imaging.PixelFormat.DontCare, 1, 1) ========================================= Please, try the same issue using this code.
