Hi,
I would like to convert a Tiff image from Palette to Grayscale. The
image has following structure (gdalinfo):
Driver: GTiff/GeoTIFF
Size is 13779, 9449
Coordinate System is `'
Origin = (567499.841250,146000.158750)
Pixel Size = (0.31750000,-0.31750000)
Metadata:
TIFFTAG_SOFTWARE=IrfanView
TIFFTAG_XRESOLUTION=400
TIFFTAG_YRESOLUTION=400
TIFFTAG_RESOLUTIONUNIT=2 (pixels/inch)
Image Structure Metadata:
COMPRESSION=LZW
Corner Coordinates:
Upper Left ( 567499.841, 146000.159)
Lower Left ( 567499.841, 143000.101)
Upper Right ( 571874.674, 146000.159)
Lower Right ( 571874.674, 143000.101)
Center ( 569687.258, 144500.130)
Band 1 Block=13779x4 Type=Byte, ColorInterp=Palette
Metadata:
NBITS=1
Color Table (RGB with 2 entries)
0: 255,255,255,255
1: 0,0,0,255
and i would like to process it with "convert" to get following format:
Driver: GTiff/GeoTIFF
Size is 13779, 9449
Coordinate System is `'
Origin = (567499.841250,146000.158750)
Pixel Size = (0.31750000,-0.31750000)
Metadata:
TIFFTAG_SOFTWARE=Adobe Photoshop CS2 Windows
TIFFTAG_DATETIME=2006:11:28 19:03:48
TIFFTAG_XRESOLUTION=400
TIFFTAG_YRESOLUTION=400
TIFFTAG_RESOLUTIONUNIT=2 (pixels/inch)
Image Structure Metadata:
COMPRESSION=LZW
Corner Coordinates:
Upper Left ( 567499.841, 146000.159)
Lower Left ( 567499.841, 143000.101)
Upper Right ( 571874.674, 146000.159)
Lower Right ( 571874.674, 143000.101)
Center ( 569687.258, 144500.130)
Band 1 Block=13779x19 Type=Byte, ColorInterp=Gray
I've tried many options with convert, but it doesn't work. Could you
help me? I'd like to process my images with imagemagick and not
photoshop. ,-)
Best regards,
Emmanuel BELO
