The mapping is as follows: -.sp -.TS -center; -lb cb cb cb cb cb cb -l c c c c c c. -_ -Internal Format Red Green Blue Alpha Luminance Intensity -_ -_const(ALPHA) A -_const(LUMINANCE) R -_const(LUMINANCE_ALPHA) A R -_const(INTENSITY) R -_const(RGB) R G B -_const(RGBA) R G B A -_ -.TE -.sp -The red, green, blue, alpha, luminance, and/or intensity components of -the resulting pixels are stored in floating-point rather than integer -format. -They form a two-dimensional filter kernel image indexed with coordinates -\f2i\fP and \f2j\fP such that \f2i\fP starts at zero and increases from left -to right, and \f2j\fP starts at zero and increases from bottom to top. -Kernel location \f2i,j\fP is derived from the \f2N\fPth pixel, -where \f2N\fP is \f2i\fP+\f2j\fP*__width. -.PP -Note that after a convolution is performed, the resulting color -components are also scaled by their corresponding -_const(POST_CONVOLUTION_c_SCALE) parameters and biased by their -corresponding _const(POST_CONVOLUTION_c_BIAS) parameters (where -\f2c\fP takes on the values \f3RED\fP, \f3GREEN\fP, \f3BLUE\fP, and -\f3ALPHA\fP). -These parameters are set by _cmnd(PixelTransfer). -.SH NOTES -_cmnd is present only if _arbstring(imaging) is returned when _cmnd(GetString) -is called with an argument of _const(EXTENSIONS). -.SH ERRORS -_const(INVALID_ENUM) is generated if __target is not -_const(CONVOLUTION_2D). -.P -_const(INVALID_ENUM) is generated if __internalformat is not one of the -allowable values. -.P -_const(INVALID_VALUE) is generated if __width is less than zero or greater -than the maximum supported value. -This value may be queried with _cmnd(GetConvolutionParameter) -using target _const(CONVOLUTION_2D) and name -_const(MAX_CONVOLUTION_WIDTH). -.P -_const(INVALID_VALUE) is generated if __height is less than zero or greater -than the maximum supported value. -This value may be queried with _cmnd(GetConvolutionParameter) -using target _const(CONVOLUTION_2D) and name -_const(MAX_CONVOLUTION_HEIGHT). -.P -_const(INVALID_ENUM) is generated if __format is not one of the allowable -values. -.P -_const(INVALID_ENUM) is generated if __type is not one of the allowable -values. -.P -_const(INVALID_OPERATION) is generated if _cmnd is executed -between the execution of _cmnd(Begin) and the corresponding -execution of _cmnd(End). -.P -_const(INVALID_OPERATION) is generated if _param4 is one of -_const(UNSIGNED_BYTE_3_3_2), -_const(UNSIGNED_BYTE_2_3_3_REV), -_const(UNSIGNED_SHORT_5_6_5), or -_const(UNSIGNED_SHORT_5_6_5_REV) -and _param5 is not _const(RGB). -.P -_const(INVALID_OPERATION) is generated if _param4 is one of -_const(UNSIGNED_SHORT_4_4_4_4), -_const(UNSIGNED_SHORT_4_4_4_4_REV), -_const(UNSIGNED_SHORT_5_5_5_1), -_const(UNSIGNED_SHORT_1_5_5_5_REV), -_const(UNSIGNED_INT_8_8_8_8), -_const(UNSIGNED_INT_8_8_8_8_REV), -_const(UNSIGNED_INT_10_10_10_2), or -_const(UNSIGNED_INT_2_10_10_10_REV) -and _param5 is neither _const(RGBA) nor _const(BGRA). -.SH ASSOCIATED GETS -_cmnd(GetConvolutionParameter), _cmnd(GetConvolutionFilter) -.SH SEE ALSO -_cmnd(ConvolutionFilter1D), -_cmnd(SeparableFilter2D), -_cmnd(ConvolutionParameter), -_cmnd(PixelTransfer) |
