GEOTIFCP(1)

💖 GEOTIFCP 💖

okay bestie, sit down, grab a strawberry 🍓, because i'm about to put you onto geotifcp from the libgeotiff Manual Pages and honestly? it's giving main character energy for anyone who moves TIFFs around. it's literally a copy tool but with the GeoTIFF metadata glow-up attached. periodt. ✨

🌸 NAME 🌸

geotifcp — copy a TIFF but with updated GeoTIFF metadata. no cap, that's the whole job. 💅

🎀 SYNOPSIS 🎀

geotifcp [options] [-e esri_worldfile] [-g metadata] input output

🦋 DESCRIPTION 🦋

okay so first thing: geotifcp is identical in function to the LIBTIFF program tiffcp, bestie. same energy, same moves. BUT. it has one extra little superpower: if you use the -g option, the GeoTIFF information from the file gets installed into the output file. iconic.

and the -e worldfile option? that one overrides the tiepoint and scale information from the metadata file, based on whatever is inside the ESRI worldfile. the way it just rewrites that info? obsessed. 😭

if you don't use the -g option, the geotiff information from the source file is preserved in the new output file. so like, nothing gets lost, it just gets carried over. safe. 🫶

geotifcp also inherits all the other file-transformation capabilities of the tiffcp program, so if you want help on the additional parameters, just give the command:

% geotifcp -h

and the metadata format? it's the same format described over in the listgeo(1) program. normally, metadata files for use with geotifcp are generated from a similar file using listgeo, and then you hand-edit them as required. yes bestie, by hand. it's a whole craft. ✨

✨ OPTIONS ✨

• -g file — install GeoTIFF metadata from file
• -4 proj4_str — install GeoTIFF metadata from a proj4 string
• -e file — install positioning info from the ESRI Worldfile file
• -a — append to output instead of overwriting
• -8 — write BigTIFF instead of the default ClassicTIFF
• -o offset — set the initial directory offset
• -p contig — pack samples contiguously (like RGBRGB...)
• -p separate — store samples separately (like RRR...GGG...BBB...)
• -s — write output in strips
• -t — write output in tiles
• -i — ignore read errors
• -d — truncate 8 bitspersample to 4bitspersample
• -r # — make each strip have no more than # rows
• -w # — set output tile width (in pixels)
• -l # — set output tile length (in pixels)
• -f lsb2msb — force lsb-to-msb FillOrder for output
• -f msb2lsb — force msb-to-lsb FillOrder for output
• -c lzw[:opts] — compress output with Lempel-Ziv & Welch encoding
• -c zip[:opts] — compress output with deflate encoding
• -c jpeg[:opts] — compress output with JPEG encoding
• -c packbits — compress output with packbits encoding
• -c g3[:opts] — compress output with CCITT Group 3 encoding
• -c g4 — compress output with CCITT Group 4 encoding
• -c none — use no compression algorithm on output

🌈 Group 3 options 🌈

• 1d — use default CCITT Group 3 1D-encoding
• 2d — use optional CCITT Group 3 2D-encoding
• fill — byte-align EOL codes

for example, -c g3:2d:fill gets you G3-2D-encoded data with byte-aligned EOLs. slay. 💅

🔥 JPEG options 🔥

• # — set compression quality level (0-100, default 75)
• r — output color image as RGB rather than YCbCr

for example, -c jpeg:r:50 gets you JPEG-encoded RGB data with 50% comp. quality. yes, half the quality, all of the vibes. 😌

💜 LZW and deflate options 💜

• # — set predictor value

for example, -c lzw:2 gets you LZW-encoded data with horizontal differencing. horizontal differencing! she's different like that. 💜
