Dear list: This is my first time try convert(1). I did this: $ convert 1329.jpg 1330.jpg -adjoin identity.tiff
The two images are here: gopher://sdf.lonestar.org/I/users/weiwu/1329.jpg gopher://sdf.lonestar.org/I/users/weiwu/1330.jpg Both images are less then 300KB in size, however the converted tiff image is as big as 1331KB. This is strange as tiff file is twice as big as it should be. As compression method shouldn't been changed (still JPEG inside the TIFF) I wonder how this comes to be and, is there a way to generate tiff image less then 600KB? Thanks in advance! I also tested the generated tiff image to make sure it's still in JPEG compression: [EMAIL PROTECTED]:/tmp> identify -verbose identity.tiff Image: identity.tiff Format: TIFF (Tagged Image File Format) Class: DirectClass Geometry: 1090x682 Type: TrueColor Endianess: MSB Colorspace: RGB Channel depth: Red: 8-bit Green: 8-bit Blue: 8-bit Channel statistics: Red: Min: 0 (0) Max: 255 (1) Mean: 210.407 (0.825124) Standard deviation: 56.3656 (0.221042) Green: Min: 0 (0) Max: 255 (1) Mean: 207.888 (0.815247) Standard deviation: 57.746 (0.226455) Blue: Min: 0 (0) Max: 255 (1) Mean: 218.063 (0.85515) Standard deviation: 59.2252 (0.232256) Colors: 217255 Rendering intent: Undefined Resolution: 300x300 Units: PixelsPerInch Filesize: 1.21981mb Interlace: None Background color: white Border color: rgb(223,223,223) Matte color: grey74 Transparent color: black Page geometry: 1090x682+0+0 Dispose: Undefined Iterations: 0 Scene: 0 of 2 Compression: JPEG Orientation: TopLeft Document: identity.tiff Signature: 7d39a85d2fd208b09bbdb7024626ff3b748fb54d05054133c7b93d881dde094a Software: ImageMagick 6.2.4 02/15/07 Q16 http://www.imagemagick.org Tainted: False Version: ImageMagick 6.3.0 11/27/06 Q16 http://www.imagemagick.org Image: identity.tiff Format: TIFF (Tagged Image File Format) Class: DirectClass Geometry: 1084x676 Type: TrueColor Endianess: MSB Colorspace: RGB Channel depth: Red: 8-bit Green: 8-bit Blue: 8-bit Channel statistics: Red: Min: 0 (0) Max: 255 (1) Mean: 215.469 (0.844978) Standard deviation: 55.8373 (0.21897) Green: Min: 0 (0) Max: 255 (1) Mean: 209.302 (0.820794) Standard deviation: 62.2949 (0.244294) Blue: Min: 0 (0) Max: 255 (1) Mean: 219.628 (0.861284) Standard deviation: 62.5139 (0.245153) Colors: 199496 Rendering intent: Undefined Resolution: 300x300 Units: PixelsPerInch Filesize: 1.21981mb Interlace: None Background color: white Border color: rgb(223,223,223) Matte color: grey74 Transparent color: black Page geometry: 1084x676+0+0 Dispose: Undefined Iterations: 0 Scene: 1 of 2 Compression: JPEG Orientation: TopLeft Document: identity.tiff Signature: 0b2550953bb2dd12eda81f4496f40c9127d46c0bdeb8aa14bc2775b055cd21b9 Software: ImageMagick 6.2.4 02/15/07 Q16 http://www.imagemagick.org Tainted: False User time: 0.920u Elapsed time: 0:02 Pixels per second: 715.607kb Version: ImageMagick 6.3.0 11/27/06 Q16 http://www.imagemagick.org -- Zhang Weiwu Real Softservice http://www.realss.com +86 592 2091112 _______________________________________________ Magick-users mailing list [email protected] http://studio.imagemagick.org/mailman/listinfo/magick-users
