so, there was https://sourceforge.net/p/dktools/wiki/bitmap2pp/ suggested by another web page I compiled those tools on Slackware 15.0 i586 and resulting files are: bash-5.1$ du -h ~/CinGG_e2k_june_2020_remote* 300K /home/guest/CinGG_e2k_june_2020_remote-fs8.pdf 200K /home/guest/CinGG_e2k_june_2020_remote-fs8.png 500K /home/guest/CinGG_e2k_june_2020_remote.pdf 480K /home/guest/CinGG_e2k_june_2020_remote.png so normal png is 480kb, pdf is 20kb bigger, optimized (lossely) png is 200kb and pdf done from that is 300kb. 300 << 480 .... I tried resulting pdf file in KPDF from TDE 14.0.13 and they show up there. >> >> >>> >>> But I guess html version can benefit from smaller pngs too? >>> >>>> >>>> -- >>>> Stefan >>>> -- >>>> Cin mailing list >>>> Cin@lists.cinelerra-gg.org >>>> https://lists.cinelerra-gg.org/mailman/listinfo/cin -- Cin mailing list Cin@lists.cinelerra-gg.org https://lists.cinelerra-gg.org/mailman/listinfo/cin
