This extra channel usually defines a mask which represents 2962 a sort of a cookie-cutter for the image. This is the case when matte is 2963 255 (full coverage) for pixels inside the shape, zero outside, and between 2964 zero and 255 on the boundary. If image does not have a matte channel, it 2965 is initialized with 0 for any pixel matching in color to pixel location 2966 (0,0), otherwise 255. See <a href="#disp-matt">Matte Editing</a> for a method 2967 of defining a matte channel. 2968 <p> 2969 If you choose <strong>blend</strong>, the composite operator becomes <strong>over</strong>. 2970 The image matte channel percent transparency is initialized to factor. 2971 The image window is initialized to (100-factor). Where factor is the value 2972 you specify in the Dialog widget. 2973 <p> 2974 <strong>Displace</strong> shifts the image pixels as defined by a displacement map. 2975 With this option, <em>image</em> is used as a displacement map. Black, within 2976 the displacement map, is a maximum positive displacement. White is a maximum 2977 negative displacement and middle gray is neutral. The displacement is scaled 2978 to determine the pixel shift. By default, the displacement applies in both 2979 the horizontal and vertical directions. However, if you specify 2980 <em>mask</em>, 2981 <em>image</em> 2982 is the horizontal X displacement and 2983 <em>mask</em> the vertical Y displacement. 2984 <p> 2985 Note that matte information for image window is not retained for colormapped 2986 X server visuals (e.g. 2987 <em>StaticColor, StaticColor, GrayScale, PseudoColor</em>). 2988 Correct compositing behavior may require a <em>TrueColor</em> or 2989 <em>DirectColor</em> 2990 visual or a <em>Standard Colormap</em>. 2991 <p> 2992 Choosing a composite operator is optional.

However, the color that 2998 appears in image window may be different. For example, on a monochrome 2999 screen Image window will appear black or white even though your composited 3000 image may have many colors. If the image is saved to a file it is written 3001 with the correct colors.

The transparent 3395 color updates the image matte channel and is useful for image compositing. 3396 <p> 3397 If you choose the color browser and press <strong>Grab</strong>, you can select the 3398 primitive color by moving the pointer to the desired color on the screen 3399 and press any button. The transparent color updates the image matte channel 3400 and is useful for image compositing. 3401 <p> 3402 Choose a stipple, if appropriate, from the <strong>Stipple</strong> sub-menu. Additional 3403 stipples can be specified with the file browser. Stipples obtained from 3404 the file browser must be on disk in the X11 bitmap format. 3405 <p> 3406 Choose a line width, if appropriate, from the <strong>Width</strong> sub-menu. To 3407 choose a specific width select the <strong>Dialog</strong> widget. 3408 <p> 3409 Choose a point in the image window and press button 1 and hold. Next, move 3410 the pointer to another location in the image. As you move, a line connects 3411 the initial location and the pointer. When you release the button, the 3412 image is updated with the primitive you just drew. For polygons, the image 3413 is updated when you press and release the button without moving the pointer. 3414 <p> 3415 To cancel image drawing, move the pointer back to the starting point of 3416 the line and release the button. 3417 </td></tr></table> 3418 <p> 3419 <i><a href="#top">Back to Contents</a></i> 3420 </p> 3421 <table BORDER=0 WIDTH="100%"> 3422 <tr> 3423 <td ALIGN=LEFT bgcolor="#FFFFFF"><img 3424 SRC="images/right_triangle.png" ALT=">" BORDER=0 3425 height=14 width=15><b><font face="Helvetica, Arial"><font 3426 color="#00B04F"><font size="+1"> 3427 <a NAME="disp-regi"></a>Region of Interest 3428 </font></font></font></b></td></tr></table> 3429 <table width="94%" border="0" cellspacing="0" cellpadding="8"> 3430 <tr><td width="3%"><br></td><td> 3431 <p> 3432 To begin, press choose Region of Interest of the Pixel Transform sub-menu 3433 from the <a href="#disp-comm">Command widget</a>. 3434 Alternatively, <a href="#disp-keyb">press</a> R in the image window. 3435 <p> 3436 A small window appears showing the location of the cursor in the image 3437 window.
