Problem with Images in Report

edited August 2009 in FastReport .NET
Hi @all

First, sorry about my bad English.

I have the following Problem.

I have a Report which take the Images from a Datatable --> Image.ImageLocation = ((String)Report.GetColumnValue("db_hamapict.fld_bilddatei"));

The Problem is that the Images are to large, and the System run out of Memory during Report-Creation.

In VB.NET i have a Code that Resize the Image to Display it.

But, how can I tell Fast-Report.NET to Resize Images before Display it?

Any Ideas ?

Thanks a lot.

Greetings from Switzerland.

Ronny

    Hello,

    If you don't need full-size images, you may use thumbnails. To do this, clear the ImageLocation property of the Picture object and create the BeforePrint event handler:
    private void Picture1_BeforePrint(object sender, EventArgs e)
    {
      string fileName = ((String)Report.GetColumnValue("db_hamapict.fld_bilddatei"));
      using (Bitmap bmp = new Bitmap(fileName))
      {
        // create 400x300 pixels thumbnail 
        Picture1.Image = bmp.GetThumbnailImage(400, 300, null, IntPtr.Zero);
      }
    }

    Hi

    Sounds very good. Thank you.

    I have copy the code an editet to my environment. But unfortunately I get an other Error.


    MyCode now:
    private void Image_BeforePrint(object sender, EventArgs e)
    {
    string fileName = ((String)Report.GetColumnValue("db_hamapict.fld_bilddatei"));
    using (Bitmap bmp = new Bitmap(fileName))
    {
    // create 400x300 pixels thumbnail
    Image.Image = bmp.GetThumbnailImage(400, 300, null, IntPtr.Zero);

    Any Ideas ? The Idea with the Thumbnail sounds very nice, i think with this Idea we are on the right course.

    Greetings.

    Hello,

    Most probably, you pass wrong fileName (file not exist, or bad-formed path) to the Bitmap constructor.
    The correct code that checks for file existence:
    private void Picture1_BeforePrint(object sender, EventArgs e)
    {
      string fileName = ((String)Report.GetColumnValue("db_hamapict.fld_bilddatei"));
      if (!System.IO.File.Exists(fileName))
      {
        Picture1.Image = null;
        return;
      }
    
      using (Bitmap bmp = new Bitmap(fileName))
      {
        // create 400x300 pixels thumbnail
        Picture1.Image = bmp.GetThumbnailImage(400, 300, null, IntPtr.Zero);
      }
    }

    Use ratio instead of hardcoded sizes:
    float ratio = 0.3f;
    // you can even make ratio dynamic, depending on original image size
    if (bmp.Width < 1000)
      ratio = 0.5f;
    if (bmp.Width < 500)
      ratio = 0.7f;
    Picture1.Image = bmp.GetThumbnailImage((int)Math.Round(bmp.Width * ratio), (int)Math.Round(bmp.Height * ratio), null, IntPtr.Zero);

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
