Name

write_lutwrite_lutWriteLutwrite_lutWriteLutWriteLut — Write look-up-table (lut) as file.

Signature

write_lut( : : WindowHandle, FileName : )

Herror write_lut(const Hlong WindowHandle, const char* FileName)

Herror T_write_lut(const Htuple WindowHandle, const Htuple FileName)

Herror write_lut(const HTuple& WindowHandle, const HTuple& FileName)

void HWindow::WriteLut(const HTuple& FileName) const

void WriteLut(const HTuple& WindowHandle, const HTuple& FileName)

void HWindow::WriteLut(const HString& FileName) const

void HWindow::WriteLut(const char* FileName) const

void HOperatorSetX.WriteLut(
[in] VARIANT WindowHandle, [in] VARIANT FileName)

void HWindowX.WriteLut([in] BSTR FileName)

static void HOperatorSet.WriteLut(HTuple windowHandle, HTuple fileName)

void HWindow.WriteLut(string fileName)

Description

write_lutwrite_lutWriteLutwrite_lutWriteLutWriteLut saves the look-up-table (resp. the part of it that is relevant for displaying image gray values) of the valid output window into a file named 'FileNameFileNameFileNameFileNameFileNamefileName.lut'. It can be read again later with set_lutset_lutSetLutset_lutSetLutSetLut.

Attention

write_lutwrite_lutWriteLutwrite_lutWriteLutWriteLut is only suitable for systems using 256 colors.

File extension: .lut

Example (HDevelop)

read_image(Image,'monkey')
dev_display(Image)
draw_lut(WindowHandle)
write_lut(WindowHandle,'test_lut')

Example (C)

read_image(&Image,"monkey") ;
disp_image(Image,WindowHandle) ;
draw_lut(WindowHandle) ;
write_lut(WindowHandle,"test_lut") ;

Example (HDevelop)

read_image(Image,'monkey')
dev_display(Image)
draw_lut(WindowHandle)
write_lut(WindowHandle,'test_lut')

Example (HDevelop)

read_image(Image,'monkey')
dev_display(Image)
draw_lut(WindowHandle)
write_lut(WindowHandle,'test_lut')

Example (HDevelop)

read_image(Image,'monkey')
dev_display(Image)
draw_lut(WindowHandle)
write_lut(WindowHandle,'test_lut')

Example (HDevelop)

read_image(Image,'monkey')
dev_display(Image)
draw_lut(WindowHandle)
write_lut(WindowHandle,'test_lut')

Result

write_lutwrite_lutWriteLutwrite_lutWriteLutWriteLut returns 2 (H_MSG_TRUE) if the window with the required properties (256 colors) is valid and the parameter (file name) is correct. Otherwise an exception is raised.
