   * if >0, the loaded image is forced to be color 3-channel image; 
   * if 0, the loaded image is forced to be grayscale; 
-  * if 
+  * if <0, the loaded image will be loaded as is (with number of channels depends on the file). 
+
+### CvSaveImage
+
+This block saves the image in input, to the specified file. The image format is chosen depending on the filename extension, [ see CvLoadImage](_OpenCV#CvLoadImage_). 
+
+### CvShowImage
+
+This block display the image in input, in a window. 
+
+  * WNDOW_TITLE: Name of the widow. Don't forget to use different name to create new windows! 
+  * FLAGS: If it is set to 1, window size is automatically adjusted to fit the displayed image, while user can not change the window size manually. 
+
+### CvCreateImage
+
+Create a black image (all the pixel are initialized to 0) with specified: 
+
+  * Size: you could specified its width and height 
+  * Bit depth of image elements: can be one of: 
+    * IPL_DEPTH_8U - unsigned 8-bit integers 
+    * IPL_DEPTH_8S - signed 8-bit integers 
+    * IPL_DEPTH_16U - unsigned 16-bit integers 
+    * IPL_DEPTH_16S - signed 16-bit integers 
+    * IPL_DEPTH_32S - signed 32-bit integers 
+    * IPL_DEPTH_32F - single precision floating-point numbers 
+    * IPL_DEPTH_64F - double precision floating-point numbers 
+  * Channels: number of channels per element (pixel). Can be 1, 2, 3 or 4.

+## Draw
+
+This sub menu contains many function to draw some figures on an image 
+
+### CvLine
+
+This block draws the line segment between two points in the image. For non-antialiased lines with integer coordinates the 8-connected or 4-connected Bresenham algorithm is used. Thick lines are drawn with rounding endings. Antialiased lines are drawn using Gaussian filtering. LINE_TYPE : 
+
+  * 8 - 8-connected line. 
+  * 4 - 4-connected line. 
+  * CV_AA - antialiased line. 
+
+The color, in input, specified for the line is in RGB. 
+
+Example with a black image of size 400x400, line [(50,50);(350,350)] and LINE_TYPE=8 : 
+
+[800px| ](Image:line.jpg_) 
+
+### CvRectangle
+
+This block draws simple, thick or filled rectangle two opposite corners. 
+
+  * THICKNESS: Thickness of lines that make up the rectangle. Negative values make the function to draw a filled rectangle. 
+  * LINE_TYPE: Type of the line, see CvLine description 
+  * SHIFT: Number of fractional bits in the point coordinates. 
+
+The color, in input, specified for the rectangle is in RGB. 
+
+Example where the small rectangle is filled and the big no : 
+
+[800px| ](Image:rectangle.jpg_) 
+
+## Arithmetic, Logic and Comparison
+
+This sub menu contains many function to perform some arithmetic, logic and comparison operation between some images. 
+
+### CvAdd
+
+This block adds one array to another one: 
+    
+    dst(I)=src1(I)+src2(I)
+    
+
+The images must have the same type and the same size. 
+
+### CvComp
+
+This block compares the corresponding elements of two images. Both image must have a single channel. The flag CMP_OP specifying the relation between the elements to be checked: 
+
+  * CV_CMP_EQ - src1(I) "equal to" src2(I) 
+  * CV_CMP_GT - src1(I) "greater than" src2(I) 
+  * CV_CMP_GE - src1(I) "greater or equal" src2(I) 
+  * CV_CMP_LT - src1(I) "less than" src2(I) 
+  * CV_CMP_LE - src1(I) "less or equal" src2(I) 
+  * CV_CMP_NE - src1(I) "not equal to" src2(I) 
+    
+    dst(I)=src1(I) op src2(I),
+    
+
+where op is '=', '>', '>=', '
