描述
算子 gen_image_constgen_image_constGenImageConstGenImageConstGenImageConstgen_image_const creates an image of the indicated
size. The width and height of the image are determined by
WidthWidthWidthWidthwidthwidth and HeightHeightHeightHeightheightheight. HALCON supports the following
image types:
- 'byte'"byte""byte""byte""byte""byte"
-
1 byte per pixel, unsigned
Value range: (0..255)
- 'int1'"int1""int1""int1""int1""int1"
-
1 byte per pixel, signed
Value range: (-128..127)
- 'uint2'"uint2""uint2""uint2""uint2""uint2"
-
2 bytes per pixel, unsigned
Value range: (0..65535)
- 'int2'"int2""int2""int2""int2""int2"
-
2 bytes per pixel, signed
Value range: (-32768..32767)
- 'int4'"int4""int4""int4""int4""int4"
-
4 bytes per pixel, signed
Value range: (-2147483648..2147483647)
- 'int8'"int8""int8""int8""int8""int8"
-
8 bytes per pixel, signed
(only available on 64 bit systems)
Value range: (-9223372036854775808..9223372036854775807)
- 'real'"real""real""real""real""real"
-
4 bytes per pixel, floating point
Value range: (-3.4e38..3.4e38)
Precision: 6 significant decimal digits
- 'complex'"complex""complex""complex""complex""complex"
Two matrices of type 'real'"real""real""real""real""real"
- 'vector_field_relative'"vector_field_relative""vector_field_relative""vector_field_relative""vector_field_relative""vector_field_relative"
-
Two matrices of type 'real'"real""real""real""real""real"
Interpretation: Vectors
- 'vector_field_absolute'"vector_field_absolute""vector_field_absolute""vector_field_absolute""vector_field_absolute""vector_field_absolute"
-
Two matrices of type 'real'"real""real""real""real""real"
Interpretation: Absolute coordinates
- 'direction'"direction""direction""direction""direction""direction"
-
1 byte per pixel, unsigned
Value range: (0..179)
Interpretation: Angle divided by two
Attention: The values 180..254 are automatically set to the value
255, which is interpreted as undefined angle.
- 'cyclic'"cyclic""cyclic""cyclic""cyclic""cyclic"
-
1 byte per pixel, unsigned, cyclic arithmetics
Value range: (0..255)
With the operator
set_system('init_new_image',<'true'/'false'>)set_system("init_new_image",<"true"/"false">)SetSystem("init_new_image",<"true"/"false">)SetSystem("init_new_image",<"true"/"false">)SetSystem("init_new_image",<"true"/"false">)set_system("init_new_image",<"true"/"false">), it can be
controlled whether the created image is initialized with 0 or not.
执行信息
- 多线程类型：可重入（与非独占算子并行运行）。
- 多线程作用域：全局（可从任何线程调用）。
- 未采用并行化处理。

示例（C）
gen_image_const(&New,"byte",width,height);
get_image_pointer1(New,(Hlong*)&pointer,type,&width,&height);
for (row=0; row<height-1; row++)
{
for (col=0; col<width-1; col++)
{
pointer[row*width+col] = (row + col) % 256;
}
}
结果
如果参数值正确，算子 gen_image_constgen_image_constGenImageConstGenImageConstGenImageConstgen_image_const 返回值 2 ( H_MSG_TRUE )。否则将抛出异常。
