imageTagger 0.5 (Default branch)

ImageimageTagger makes it easy to manage tags ofdifferent images and so organise large collectionsof image collections. It features the ability toassign free tags to images and to search forpictures with tags. The tags are storedexternally, so this can also be used for filesthat should not be changed, files on CDs, andpictures in a format that does not supportmetadate. No image data is changed ever.License: GNU General Public License (GPL)Changes:
This release adds the ability to search for new images in directories. It has a slightly enhanced help function.Image

NAME
tiff2rgba - convert a TIFF image to RGBA color space SYNOPSIS
tiff2rgba [ options ] input.tif output.tif DESCRIPTION
Tiff2rgba converts a wide variety of TIFF images into an RGBA TIFF image. This includes the ability to translate different color spaces and photometric interpretation into RGBA, support for alpha blending, and translation of many different bit depths into a 32bit RGBA image. Internally this program is implemented using the TIFFReadRGBAImage() function, and it suffers any limitations of that image. This includes limited support for > 8 BitsPerSample images, and flaws with some esoteric combinations of BitsPerSample, photometric interpretation, block organization and planar configuration. The generated images are stripped images with four samples per pixel (red, green, blue and alpha) or if the -n flag is used, three samples per pixel (red, green, and blue). The resulting images are always planar configuration contiguous. For this reason, this program is a useful utility for transform exotic TIFF files into a form ingestable by almost any TIFF supporting software. OPTIONS
-c Specify a compression scheme to use when writing image data: -c none for no compression (the default), -c packbits for the PackBits compression algorithm, -c zip for the Deflate compression algorithm, -c jpeg for the JPEG compression algorithm, and -c lzw for Lem- pel-Ziv & Welch. -r Write data with a specified number of rows per strip; by default the number of rows/strip is selected so that each strip is approxi- mately 8 kilobytes. -b Process the image one block (strip/tile) at a time instead of by reading the whole image into memory at once. This may be necessary for very large images on systems with limited RAM. -n Drop the alpha component from the output file, producing a pure RGB file. Currently this does not work if the -b flag is also in effect. SEE ALSO
