Hello

 

Our user want to print a image and insert into document. I have to set the size in the print settings so the image can be fit in the document 

 

?_img_ alt="User-added image" src="https://latitudegeo--c.na53.content.force.com/servlet/rtaImage?eid=906600000004IRO&feoid=Body&refid=0EM600000004XrR"_/_img_

 

The problem is:

 

When user print the map, if user choose to use current extent, the scale of the printed map will change. If user choose to use current scale, the printed map only display part of the map.

 

Example:

 

current map 

 

_img_ alt="User-added image" src="https://latitudegeo--c.na53.content.force.com/servlet/rtaImage?eid=906600000004IRO&feoid=Body&refid=0EM600000004XrW"_/_img_

 

Print image (current extent)

 

_img_ alt="User-added image" src="https://latitudegeo--c.na53.content.force.com/servlet/rtaImage?eid=906600000004IRO&feoid=Body&refid=0EM600000004Xrb"_/_img_

 

print image (current scale)

 

_img_ alt="User-added image" src="https://latitudegeo--c.na53.content.force.com/servlet/rtaImage?eid=906600000004IRO&feoid=Body&refid=0EM600000004Xrg"_/_img_

 

How to sove the problem?

 

Is that possible to print map in current scale and show full extension and resize the image?

 

Thanks

  Long,

   

  You may set the output image width/height based on your report's image control size along with the map DPI which is usually 96.

   

  For example, considiering that your .rpt (your report) has a Picture control whose size is 7 inch by 2 inch, and map_dpi - 96 to be exported, the image width and height on the 'Export Map', or 'Extract FeatureMap' activity on your workflow SHOULD set as 7 * 96 and 2 * 96.

   

  So I recomment you can set thw three configuration values: outWidthInch, outHeightInch and DPI, which are constant values, and then use them to set Image Width and Image Height to be exported for the report's data source.

   

  wish this helps you out.

  Long, would you be willing to share your C# script, please? I'm trying to resolve a scale issue in a report, and am thinking your code might help to lead me in the right direction.

   

  Thanks,

  Hi Justin

   

  What I do is to resize the image file. Here are the steps

   

  1. DownloadImage 

   

  2. GetBytesFromImage

   

  3. Use C# script to save into web site

   

  System.Drawing.Size size = new System.Drawing.Size(450,300);

   

  System.Drawing.Bitmap oldImage = (System.Drawing.Bitmap)System.Drawing.Bitmap.FromStream(new System.IO.MemoryStream(tempByte));

   

  System.Drawing.Bitmap newImage = new System.Drawing.Bitmap(oldImage, size);

   

  newImage.Save("C:\\inetpub\\wwwroot\\TempFile\\NotificationImage.jpg");

   

  Hope it will be helpful

   

  cheers
