Destructor
| void setPixel (int iX, int iY, Type tValue)
| setPixel |
Assigns a new value to the pixel at the specified position.
Parameters:
| iX | x-coordinate of the pixel |
| iY | y-coordinate of the pixel |
| tValue | New value |
| void setRowData (Type* pSrc,int iRow)
| setRowData |
Copies data from pSource to row iRow.
Parameters:
| iRow | Index of row |
| void resize (int iWidth, int iHeight)
| resize |
Resizes the channel.
Parameters:
| iWidth | New width |
| iHeight | New height |
| void clear ()
| clear |
clear fills each channel with zeros.
| void setChannelInfo (const char* acText)
| setChannelInfo |
Sets the channel info text (max. 64 chars).
| const char* getChannelInfo ()
| getChannelInfo |
[const]
Returns pointer to the channel info text.
| int width ()
| width |
[const]
Returns the width of the image channel
Returns: Width of channel
| int height ()
| height |
[const]
Returns the height of the image channel
Returns: height of image channel
| int depth ()
| depth |
[const]
Returns the depth in bit of the image channel
Returns: Depth of image channel in bit
| Type getPixel (int iX, int iY)
| getPixel |
[const]
Returns the value of the pixel at the specified position.
Parameters:
| iX | x-coordinate of the pixel |
| iY | y-coordinate of the pixel |
Returns: Value of specified pixel
| Type operator() (int iX, int iY)
| operator() |
[const]
Operator version of getPixel.
Parameters:
| iX | x-coordinate of the pixel |
| iY | y-coordinate of the pixel |
Returns: Value of specified pixel
| Type min ()
| min |
[const]
Returns minimal pixel value
Returns: Minimal pixel value
| Type max ()
| max |
[const]
Returns maximal pixel value
Returns: Maximal pixel value
| void scaleRange (Type tNewMin, Type tNewMax, Type tMin, Type tMax)
| scaleRange |
Scales pixel values from given min/max values to new min/max values. Values exceeding the given range are set to the new min/max values. In the SAVE mode, a warning is given for each of these pixels. For an automatic scaling use the results of min(),max() as as arguments. (Defining a range allows to compare different images.) Note: Scaling involves an internal cast to float!
Parameters:
| tNewMin | , tNewMax, New min/max values |
| tMin | , tMax, Assumed min/max values |
| vector | histogram |
[const]
Calculates a histogram given min, max, #bins
Parameters:
| fMin | Minimum bin value |
| fMax | Maximum bin value |
| iNbBins | Number of bins |
| int refs ()
| refs |
[const]
Returns number of references to this object
Returns: Number of references
| void incRefCounter ()
| incRefCounter |
Increments the references counter by one
| void decRefCounter ()
| decRefCounter |
Decrements the references counter by one
| Type* getRowPtr (int iRow)
| getRowPtr |
Returns pointer on the selected row.
Parameters:
| iRow | Index of row |
| Type* getDataPtr ()
| getDataPtr |
