4.4 Work Area
4.4.1 Load Buttons
By pressing the single left or right arrow one can decrease or increase the current image
number and load the previous or next image, respectively. The double arrow will continously
increase image numbers and continuously load the next image until the stop button is
pressed.
4.4.2 Zoom Buttons
By pressing the full image button, the image will be displayed such that it fits
entirely into the window. The other buttons will zoom in or zoom out.
4.4.3 Colors
The upper text field has the same function as the "Max"−field in the mar345−Colors window
and the lower text field corresponds to the "Min"−field (see chapter 4.9). Dragging the center
mouse button in the color area, the color distribution changes. Try it out to see what
happens!. This doesn’t work for Rainbow mode (see below) and it doesn’t work on
16/24/32−bit color screens, only with 8−bit colors.
4.5 Information Areas
Upper left corner:
When pressing the center mouse button in the image area, the x,y−coordinate, intensity and
resolution of the pixel under the pointer is displayed.
Lower left corner:
Once an image has been loaded successfully, some information (wavelength, distance,
maximum intensity and average intensity) is displayed, unless "Hide statistics" was pressed
(see 4.2.2).
Upper right corner:
When pressing the "Integrate" button in the "Options" submenu (see 4.2.2) the following
information is displayed: number of pixels in x and y, maximum, minimum and average
intensity, sum of pixel intensities, standard deviation of intensities, average background and
mean intensity over background (all relative to the pixels displayed in the Image Area). The
background is calculated from a histogram of intensities of a box of 50x50 pixels around the
center of the zoomed area. Pixel values > 1000 are not included in the histogram. This option
works for zoom factors >= 1.0 only.
