| batsplat | i am trying to create a tool that accepts multiple image formats and finally places them on a pdf. can i use ghostscript to import pngs in particular for this purpose? | 10:11.02 |
| Robin_Watts | batsplat: Probably, yes. | 10:13.15 |
| | Look at the 'viewXXX' scripts in the gs library directory. | 10:13.32 |
| | There should be a viewjpg and a viewpng, I think,. | 10:13.41 |
| batsplat | Robin_Watts: thanks, lemme check that out | 10:14.11 |
| | Robin_Watts: sorry, but where do i locate the gs library directory? | 10:17.29 |
| Robin_Watts | batsplat: In the ghostscript source, there is a 'lib' directory. | 10:18.52 |
| | If you have the ghostpdl source, then it's gs/lib | 10:19.04 |
| | In there I see: viewcmyk.ps, viewgif.ps, viewjpeg.ps, viewmiff.ps, viewpbm.ps, etc. | 10:19.38 |
| | but no viewpng.ps | 10:19.42 |
| batsplat | Robin_Watts: so does this mean I can't import pngs? | 10:39.03 |
| Robin_Watts | batsplat: Well, either you can write a new viewXXX.ps file, or you can speak to ray later who may have one, or you can convert your PNG into something else and then import that. | 10:48.25 |
| tor8 | batsplat: use pngtopnm then viewpbm.ps | 11:00.57 |
| nsz | tor8 ive seen your Math.round fix but that's not correct | 11:02.22 |
| | ecma does not require the floor(x+.5) semantics, that's just a broken note in the standard | 11:02.45 |
| | i updated my article with a possible solution that gives conformant semantics | 11:03.27 |
| tor8 | nsz: yeah, I guess I should just copy mozillas copysign(floor()) thing | 11:03.28 |
| nsz | http://port70.net/~nsz/48_round.html | 11:03.38 |
| | no, copysign(floor) is wrong | 11:03.52 |
| | (it gives wrong result for 2^52 + 1 and nextafter(.5,0) and -2^52-2 etc) | 11:05.24 |
| tor8 | nsz: right. that looks like a reasonable implementation. | 11:11.31 |
| | nsz: I've pushed a commit to my local repo that I hope works better | 11:14.33 |
| nsz | ok | 11:15.25 |
| | i looked at other floating-point issues and i think dtoa and strtod needs several fixes | 11:17.13 |
| | i'll probably try to replace them with versions developed for musl if you dont mind | 11:17.46 |
| tor8 | nsz: be my guest :) | 11:49.11 |
| henrychan | How can I draw a circle annotation in a pdf ? | 14:15.00 |
| kens | I'm not aware of an annotation of type 'circle' | 14:16.46 |
| | Hmm apparently there is such a thing | 14:18.27 |
| | So the question then becomes 'using what application ?' | 14:18.52 |
| henrychan | mupdf | 14:20.33 |
| | android version | 14:20.58 |
| kens | Then I believe the answer is probably 'you can't'. I could be mistaken, but the developer who wrote the annotation code isn't here right now, so I can't check | 14:21.25 |
| henrychan | Because I found 'FZ_ANNOT_CIRCLE' in some source code, but no sample to explain how to use it | 14:23.06 |
| tor8 | kens: henrychan: the android app only supports highlight, underline, strikeout and ink annotation types | 14:23.35 |
| henrychan | yes. | 14:24.29 |
| tor8 | henrychan: MuPDFCore_addInkAnnotationInternal and MuPDFCore_addInkAnnotationInternal are where the guts of adding an annotation happen in the android app | 14:24.33 |
| | bah, MuPDFCore_addMarkupAnnotationInternal | 14:24.48 |
| | I'm not the main android developer, so take anything I say here with a grain of salt. | 14:25.23 |
| | but if you add a MuPDFCore_addCircleAnnotationInternal function modeled on those, and hook it up to the app, you have the android side done | 14:26.45 |
| | then you'll need to add circle annotation support to pdf_update_appearance | 14:26.56 |
| | the annotation creation stuff is still a work in progress, so there may be dangers lurking around the corners | 14:27.53 |
| henrychan | I think the point is doing enhancement in the 'pdf_update_appearance' , right ? | 14:29.26 |
| | any enhancement about this from v1.5 to v1.6 ?? | 14:30.50 |
| | another question, how can I save the annotations into file after call MuPDFCore_addInkAnnotationInternal ? | 14:37.52 |
| henrys | mvrhel_laptop: hey did you try out your 365 yet? | 15:00.36 |
| mvrhel_laptop | shoot I forgot about it. I got sucked into this sot bug | 15:07.45 |
| | let me do it now | 15:08.27 |
| henrys | mvrhel_laptop: no hurry just curious if I'm the only one ... paul and robin are okay | 15:09.14 |
| mvrhel_laptop | henrys: it works fine | 15:14.53 |
| | crazy user ID though | 15:15.12 |
| | heading to coffee shop bbiab | 15:15.44 |
| rayjj | kens: I closed that nonsense bug about warning suppression bug 695600 | 15:16.29 |
| henrys | mvrhel_laptop: thanks | 15:16.34 |
| kens | rayjj I was going to give him a small chance to supply an example, but hey. | 15:16.50 |
| rayjj | that guy had so many problems with his command line he probably will never get there | 15:17.15 |
| kens | I suspect he's trying to use pdfwrite to create a PDF file and send it to stdout, and that's a project doomed to failure | 15:17.16 |
| rayjj | kens: is it? pdfwrite needs to seek in the output file ? | 15:17.52 |
| kens | rayjj in general, no, in the case of a linearised file, most definitely yes. And I won't guarantee that I won't add something else that requires a real file to seek in at some point | 15:18.32 |
| Robin_Watts | rayjj, mvrhel_laptop: Your kids may like http://www.codingame.com | 16:39.05 |
| | some of the problems on there are quite interesting. | 16:39.16 |
| mvrhel_laptop | Robin_Watts: cool! | 16:39.28 |
| | I need things like this | 16:39.38 |
| Robin_Watts | I spent some time last weekend doing a load of them. | 16:39.40 |
| | and then the server crashed and lost all my progress :( | 16:39.58 |
| mvrhel_laptop | :( | 16:40.02 |
| tomty89 | hello do yo guys still have anything to do with "ghostscript fonts" | 16:40.06 |
| Robin_Watts | We do, ish. | 16:40.21 |
| tomty89 | is 8.11 still the latest version? or you include some more polished ones in certain package? | 16:41.02 |
| Robin_Watts | tomty89: We provide fonts as part of ghostscript. | 16:41.29 |
| | I think I'm right in saying that we don't package them separately any more. | 16:41.46 |
| | The guy who knows about this is chrisl, and he's away today. | 16:41.59 |
| tomty89 | so the source package here have the fonts? http://ghostscript.com/download/gsdnld.html | 16:42.26 |
| Robin_Watts | They do. | 16:42.37 |
| tomty89 | ok thanks! sorry i should check myself but somehow i can't download it successfully for now | 16:43.12 |
| rayjj | tomty89: you can also get the fonts by pulling http://git.ghostscript.com/?p=ghostpdl.git;a=tree;f=gs/Resource/Font;h=44a7a32fae0b0f7358effa1bce977bf200a5687a;hb=HEAD contents | 18:32.02 |
| | tomty89: the Aladdin Free Public License TTF URW fonts are at http://git.ghostscript.com/?p=ghostpdl.git;a=tree;f=urwfonts;h=f37e2dd371ec6ffc1c613dc1ae40bfd940b1c020;hb=HEAD | 18:33.07 |
| | tomty89: the AFPL is somewhat more restrictive than the AGPL in that it disallows ANY commercial use other than with a packaged distro | 18:33.57 |
| tomty89 | may i ask what's the format of font in Resource/Font? | 18:36.45 |
| | there're no extension names for them | 18:37.25 |
| rayjj | tomty89: sorry -- I wasn't paying attention. The Resource/Font files are all .pfb files (PostScript Type 1) | 18:39.27 |
| tomty89 | hmm when i compare the file size i thought they are afm | 18:40.22 |
| | rayjj: seems much smaller than those in the 8.11 package | 18:40.38 |
| rayjj | tomty89: the 8.11 package may have had some of the old crufty .gsf fonts in there Hershey, etc. | 18:41.32 |
| | tomty89: BTW, the correspondence to "well known" (trademarked?) font names is in Resource/Init/Fontmap. For example: /Helvetica/NimbusSanL-Regu; | 18:42.42 |
| | that means that NimbusSanL-Regu is the URW equivalent to Helvetica (which is similar to Arial) | 18:43.33 |
| tomty89 | rayjj: actually i have sort of a problem. those fonts works fine more most programs, but when it comes to libreoffice, they can't be detected. according to some, pfb only is sort of non-standard so they are not going to fix anything. | 18:44.07 |
| | rayjj: so i just wonder if i have missed some steps to use them | 18:44.19 |
| | rayjj: or maybe just afm (and pfm) wouldn't be maintained | 18:44.44 |
| rayjj | tomty89: Not sure since I don't use libreoffice. You may want to use the TTF fonts I mentioned above -- those probably will be usable | 18:45.18 |
| | useable ?? | 18:45.26 |
| tomty89 | *usable i suppose | 18:45.40 |
| rayjj | my spell checker accepts both. Don't tell my daughter that I had trouble spelling something :-) | 18:46.22 |
| tomty89 | hmm | 18:46.31 |
| | but does ghostscript provide anything to generate/convert them to afm? | 18:46.35 |
| | *ahh seems both are fine http://www.oxforddictionaries.com/definition/english/usable?q=useable | 18:47.19 |
| rayjj | tomty89: AFM is *NOT* a font format | 18:47.25 |
| | tomty89: yeah, I found http://english.stackexchange.com/questions/69709/is-useable-preferred-in-certain-regions-or-just-an-alternate-spelling-of-usa | 18:47.33 |
| | tomty89: gs can generate AFM's from Type1 fonts | 18:48.03 |
| | (in fact I am pretty sure that's what URW uses to generate the AFM's they ship) | 18:48.35 |
| | tomty89: AFM's are "Adobe Font Metric" files which are not the actual fonts, but just information *about* the fonts -- glyph widths, heights, kerning, etc. | 18:49.33 |
| tomty89 | yeah i read a bit about that | 18:50.37 |
| rayjj | tomty89: AFM's are an adjunct to fonts designed to be used by word processing programs to be able to "layout" a font (maybe one they can't even render, and use a substitute font to show in a word processing app) | 18:50.54 |
| tomty89 | what about pfm? can gs generate them as well? | 18:52.37 |
| rayjj | tomty89: gs has lib/pf2afm* The pf2afm.ps actually does the work: usage: gs [-dNODISPLAY] -- pf2afm.ps disk_font_name | 18:52.52 |
| tomty89 | yeah i found that, just notice that it only accept file with appropriate extension names | 18:53.45 |
| | i thought it was not working | 18:53.59 |
| rayjj | tomty89: i guess it is slightly bitrotted in that it needs the .pfb extension. I renamed NimbusSanL-Regu to x.pfb and ran: gs -- lib/pf2afm.ps x.pfb | 18:58.16 |
| | and it generated x.pfm | 18:58.21 |
| | tomty89: so I guess a "for" (or foreach C-shell) and a bit of basic shell magic can generate the afm's for you | 18:59.27 |
| tomty89 | yeah that's what i'm trying :D | 18:59.52 |
| rayjj | tomty89: as in: mkdir afmdict ; for f in Resource/Font/* ; do fn=`basename $f`; cp $f $fn.pfb ; echo $fn ; gs -q -- lib/pf2afm.ps $fn ; mv $fn.afm afmdict; done | 19:06.24 |
| | tomty89: note that it fails on Dingbats and StandardSymL which are "symbolic" fonts | 19:07.16 |
| | tomty89: but I'm not sure we ever had .afm files for those anyway | 19:07.39 |
| tomty89 | i think there are, tho might they might not be generated by you/gs | 19:08.27 |
| rayjj | tomty89: and that bash snippet above leaves the .pfb files laying around :-( | 19:08.36 |
| | but other than that minor bug ;-) it worked for me :-) | 19:09.08 |
| | tomty89: actually it's a "feature" since you may need file with the .pfb extension for libreoffice ;-) | 19:09.59 |
| | tomty89: and I was actually testing it on msys with gswin32c (caveat emptor) :-) | 19:11.14 |
| rayjj | thinks we need an emoticon ffor caveat emptor | 19:11.55 |
| tomty89 | unfortunately extension is not the problem for LO | 19:12.43 |
| rayjj | well, I guess you have to ask them (or hack into LO) :-( | 19:13.24 |
| | tomty89: I'm pretty sure LO uses FreeType (as gs does) so I know that the fonts are OK | 19:14.17 |
| tomty89 | yeah all other apps works without afm | 19:14.55 |
| rayjj | tomty89: not surprising that LO uses/wants the AFM -- font kerning is something that word/document processors often use. | 19:15.40 |
| | tomty89: you may try the TTF fonts -- TrueType fonts have 'kern' tables and shouldn't need any AFM | 19:16.14 |
| | tomty89: but if this used to work (gs fonts with LO) I can't imagine why it's unhappy (probably a font search path issue or something) | 19:17.14 |
| tomty89 | actually i'm an arch linux user, and i want to suggest to the devs to replace the gsfonts package in its repo, since it's built from some old fedora rpm (which consists of pfb, pfm and afm for all 35 fonts) | 19:17.45 |
| rayjj | IMHO any app that relies on "extension" to recognize file type is brain-dead/broken | 19:17.56 |
| rayjj | is chagrined at giving an arch linux user a hackish shell script | 19:18.56 |
| | we see a *LOT* of noobs here | 19:19.29 |
| tomty89 | oh i'm just a noob | 19:19.32 |
| | lol | 19:19.35 |
| rayjj | tomty89: not really a noob -- you didn't ask what the shell script meant or what to do with it ;-) | 19:20.17 |
| tomty89 | :) | 19:20.58 |
| rayjj | and I recall being a noob back in 1974 when I had trouble getting around in MIT's unix system (that I got a back door login to). | 19:22.20 |
| | I did manage to download source for their lisp system -- almost got it building on our PDP-11/70 when the semester ended | 19:23.36 |
| | time for lunch. bbiaw | 19:25.16 |
| | tomty89: good luck with LO. | 19:25.38 |
| tomty89 | thanks, see ya | 19:26.15 |
| dinamic_ | evning folks | 22:07.19 |
| | anyone around that knows mujs ? | 22:07.33 |
| | how should I iterate over an objects properties ? | 22:08.35 |
| | could I get the keys prototype property function and call it ? | 22:09.34 |
| henrys | mvrhel_laptop: sorry to bother you again but do you have the business pro version? Joann is trying to fix this. | 22:30.20 |
| mvrhel_laptop | henrys: let me check | 22:30.37 |
| | I have a business version. trying to figure out if if is pro. | 22:39.14 |
| | all these MS adjectives | 22:39.20 |
| | trying to figure out how to just install word, excel and power point I really dont want all the other stuff | 22:41.02 |
| henrys | mvrhel_laptop: install it I thought it was installed on the cloud ;-) | 22:42.30 |
| mvrhel_laptop | well there is an online version and you can download the latest desktop version | 22:42.53 |
| | but it installs everything it looks like | 22:43.06 |
| henrys | probably runs on a linux machine for security :-) | 22:43.16 |
| mvrhel_laptop | onenote, publisher, outlook. etc etc | 22:43.27 |
| | I need to clean up a few things on this machine before I go down that route | 22:43.39 |
| | but I def. have a business version henry | 22:45.00 |
| henrys | mvrhel_laptop: surprised there is a desktop version. Why wouldn't you just go buy that instead? the point is to have this accessible from all devices right? | 22:45.06 |
| mvrhel_laptop | right. but what will you do when you are on the plane? | 22:45.21 |
| | you will need to have a local copy | 22:45.36 |
| | it really assumes connectivity always | 22:45.49 |
| | it is interesting the way the "OneDrive" works | 22:46.05 |
| | you can have "local" copies of some files | 22:46.12 |
| henrys | mvrhel_laptop: I thought something minimal like the ipad app, well maybe that isn't so minimal | 22:46.35 |
| mvrhel_laptop | and everything syncs up later | 22:46.39 |
| henrys | mvrhel_laptop: is one drive mirrored on the desktop like drobbox? | 22:47.11 |
| mvrhel_laptop | yes | 22:47.15 |
| | but very integrated into windows | 22:47.22 |
| | I have about 120G on one drive | 22:47.33 |
| henrys | mvrhel_laptop: I like dropbox because of linux and mac support | 22:48.03 |
| mvrhel_laptop | right | 22:48.07 |
| | the one drive account is tied to my windows login so it just automatically shows up on my desktop, laptop and surface | 22:50.42 |
| | anyway back to the xml salt mine | 22:51.21 |
