MrSID Help


The first time you request an image, a copy of MrSID, a browser plug-in (helper) should be downloaded and installed automatically. Please note that depending on your Internet connection speed this process could take up to five minutes. This plug-in will allow you to view images, magnify portions of the images, print and save images as jpeg or bmp files. 

Should the automatic install of the plug-in not function with your browser or operating system, please download and install manually using the appropriate link below.

PC users:
Click on the button and follow the onscreen help. Link to: LIZARDTECH for PC


MAC users:
Click on the button and follow the onscreen help. Link to: LIZARDTECH for MAC

Should the manual process of installation not resolve the situation, please update your browser to an appropriate version (links below) or use the "without the plug-in" link found above each image.

  • Pan
  • Scale:

    Choose Scale to display a list of available detail levels. Click the detail level at which you would like to view your image.

  • Fit Image to Frame:
    Fit Image to Frame performs the same function as the Home tool, resizing the image to fit as closely as possible within the boundaries of the current frame size.
  • Frame Size:

    You have four predefined Frame sizes (in pixels) to choose from, as well as an option to define your own custom size. 

    Selecting Custom Size activates the Custom Size settings on the right side of the Frame Size dialog box. Type your desired values in the Width and Height boxes, both in pixels, with a minimum setting of 128. You can also use the arrows to modify the value in each field. Selecting the Change Both check box enables you to simultaneously change both the frame height and width, using either of the arrow controls. Click OK to accept your changes and display the new view or click Cancel to go back to the previous view.

    NOTE: The Frame Size option is available only to Internet Explorer users.
  • View in Frame:
    The current frame setting can be changed by toggling the View in Frame setting on or off.
  • Rotate Image:
    The Rotate Image command enables you to change the orientation of the image by selecting one of five options:
    Rotate 90 degrees
    Rotate 180 degrees 
    Rotate 270 degrees 
    Horizontal Flip
    Vertical Flip 
  • Save Image As:
    To save your image, choose Save Image As from the right-click menu to display the standard Save As dialog box. You can save only the currently visible portion of the image in JPEG (.jpg) or Windows bitmap (.bmp) format.

    Prints only the region of the image currently viewed in the Browser Plug-In. Images that are rotated on the screen print rotated.
