Bitmap


JPEG


TIFF


PPM

This format in generally used for interchange purposes (commonly Unix applications). The ASCII (text) versions are considered too bulky for storage.  The combination of options available will write the output the file in  4 Portable Map formats. Formats less than 8 bits are not supported.
 
 

Portable Bitmap Types
Output Format
Type
File Type
(P2) Portable Gray Map Gray Scale Ascii
(P5) Portable Gray Map (Raw) Gray Scale Binary
(P3) Portable Pixel Map  Color Ascii
(P6) Portable Pixel Map (Raw) Color Binary

IMG

This is the native FP Image file format. If you do not need to export your images to other applications, it is recommended that you use this as the default format.
 
 

FP Image IMG Types
Type
Numeric
Range
Byte (8 Bit) Unsigned Byte 0 to 255
Integer (16 Bit) Signed Integer -32768 to +32767
Floating Point (32 Bit) Single Precision Real  +/- 3.4 x (10^38)

Raw

To output the image to a raw format (i.e no header):

  1. From the  IMG  tab select the pixel type.
  2. From the  Other  tab select the  Binary Type
  3. Select the  Byte Ordering  that is desired.  For exporting to Intel processors choose Little Endian, Motorola uses the Big Endian  type.


Text

It is possible to export images to a text file. This data can be imported into Word Processors, Spread-Sheet programs, etc. To convert images to text, Select the  Text  type from the  Other  tab.
 

User Defined Formats

Image Processing scripts may be used for the purpose of saving images in other formats.


Copying Images to the Clipboard

Use the clipboard functions to export pictures directly to other applications. You may select the entire image or a portion of it.

The entire image:

 Click on the Copy to Clipboard   button to copy the Viewer Window contents.

Region of interest:
Click on the Save Region to Clipboard   button. Drag a box over the area that you want to copy. When the mouse button is released the image area will automatically be copied to the Clipboard.

Pasting images to an application:

In most target applications, choose the  [Edit | Paste from Clipboard]  menu option. The image will be pasted to the current cursor location.
 


Adjusting Brightness and Contrast

For 8 bit images the Window Width/Level function can be used to adjust the brightness/contrast of the image.  For 16 and 32 bit images it is necessary to visualize the range of pixels desired.

Entering the values directly:

Enter the values in the appropriate edit boxes. The changes will take effect when the Enter key is depressed.

Using the mouse:

Click on the W/L tool   button to adjust the values visually.  While the cursor is within the image area, drag the mouse up/down to adjust the level, left/right to adjust the width.

Using W/L Presets:


Dual Window Width/Level

Use the Dual Window Mode to adjust the Width/Level for 2 different ranges within the same image.  Optionally, separate color palettes may be loaded into each of the window ranges.
 


ISO Density

Use the Iso Density Mode to visually identify a range of values within the image.  Optionally, the user may also change the displayed color.
 


Using Color Palettes

For 8, 16 and 32 bit images, palettes (color look up tables) can be used to view the images in color, select gamma correction tables or to invert the image.

Loading a new palette:

  1. Click on the Load Palette  button.
  2. Select a file from the Load Palette File dialog box.
  3. You may select palettes from Pal or Bitmap files.

Image Annotation

Many image file formats include numeric and text parameters in the file.  These parameters can be displayed along with the image if desired.  Each specific format must have a corresponding FMT file describing the format (parameters, location, font, etc.) to use when displaying this text. To enable this feature select the  [Options | Image Annotation]  menu option.


Sorting Images

If displayed image files have the axis location parameter included, they may be sorted by order of location. This is accomplished by use of the  [Option | Sort Images]  sub menu functions. This function will have no effect on images that do not have specified location parameters.


Ruler Display

For images that have the pixel size (in CM) parameter specified, a calibrated ruler may be displayed on the left side of the image.
