Hi there, I use `convert' to convert some figure in tiff format (in 300dpi) to png with lower resolution:
convert -density 30 -resize 10% input.tiff output.1.png and I get the output.1.png with resolution 29 dpi. it seems right. However, if I convert the original tiff to png with the same resolution, and then convert the png to lower resolution png or tiff, I get different resolution. convert input.tiff output.2.png convert -density 30 -resize 10% output.2.png output.3.png and I get the output.3.png with resolution 76 dpi. If I convert the output.2.png to tiff format, convert -compress none output.2.png output.4.tiff and then convert -density 30 -resize 10% output.4.tiff output.5.png the resolution of output.5.png is 76 dpi. I don't know why the resolution of output.3.png and output.5.png is 76 dpi. Any cues, comments or suggestions? Thanks! P.S. the original input.tiff is obtain from GIMP with no compression.
