Hi

I need to support printing of multiple images along with header and footer. number of images can vary between 1 - 18 per page.

Can it be done automatically in Leadtools, like can i create one page out of multiple images, and leadtools can take care of scaling, positioning, etc.

Other option is to manually create one image and then add all teh images to it.

Need hep urgently.

thanks

Hello,

What is the programming interface (COM, .Net, API, OCX, etc.) that you use?

Hello,

Before printing the images, you
need to create one bog image to hold the images that you want to print.
You can create a new image by using the RasterImageCreateParameters Structure. The code (from the documentation as follows):
+------------------------------+
using Leadtools;
     private IRasterImage CreateTest(int Width, int Height)
     {
        RasterImageCreateParameters CreateParameters = new RasterImageCreateParameters();
        CreateParameters.BitsPerPixel = 24;
        CreateParameters.ManagedBuffers = 0;
        CreateParameters.ManagedTiles = 0;
        CreateParameters.DitheringMethod = RasterDitheringMethod.None;
        CreateParameters.Height = Height;
        CreateParameters.MaximumConventionalSize = 100 * 1024 * 1024;
        CreateParameters.MemoryFlags= RasterMemoryFlags.User;
        CreateParameters.NoRegionClip = true;
        CreateParameters.Order = RasterByteOrder.Bgr;
        CreateParameters.TemporaryDirectory = @"c:\";
        CreateParameters.Palette = null;
        CreateParameters.TiledThreshold = -25;
        CreateParameters.TileSize = 0;
        CreateParameters.ViewPerspective = RasterViewPerspective.TopLeft;
        CreateParameters.Width = Width;
        CreateParameters.XResolution = 0;
        CreateParameters.YResolution = 0;
        CreateParameters.UsePaletteAsLookupTable = false;
        CreateParameters.UserData = null;
        CreateParameters.UserMatchTable = null;
        //Create the image.
        IRasterImage LeadImage = new RasterImage(CreateParameters);
        if(LeadImage.IsAllocated)
           return (LeadImage);
        else
        {
           MessageBox.Show("Error, The create process failed. ", "Create Image");
           return(null);
        }
     }
+-------------------------------+

Now, if you want to fill the result image with white color, you need to call and use the FillCommand Class.
To merge and paste your images to the new created image, you need to use the CombineCommand Class.

After creating and combining the images, you can use the RasterImagePrinter Class to print the result IRasterImage.

For more information, please refer to the LEADTOOLS .Net documentation and read the following topics:
- RasterImageCreateParameters Structure.
- FillCommand Class
- CombineCommand Class
- RasterImagePrinter Class
- Print a Real Image Size in Inches
