| jamesy | Robin_Watts: thanks for the diff! | 06:07.57 |
| vv | hi, i'm having a weird problem with arial font (not embedded) showing infinity sign instead of degree sign. When embedded it shows correct degree sign | 17:55.39 |
| | anyone knows if this is an existing bug? | 17:56.08 |
| kens | hard to say with so little to go on | 17:56.28 |
| | what product ? what acyion are you taking, what is displaying the wrong glyph ? | 17:57.05 |
| vv | kens, what additional info do you need? | 17:57.06 |
| kens | ^^ | 17:57.12 |
| vv | it is on linux, i added arial ttf font to fonts folder, so it finds it ok | 17:57.33 |
| kens | abd 'it' is ? | 17:57.43 |
| vv | ok, so i run ghostscript on linux with this command: | 17:58.00 |
| | gs -o small.pdf -sDEVICE=pdfwrite -dNOPAUSE -dBATCH -dEmbedAllFonts=false -dFirstPage=467 -dLastPage=468 -dDEBUG 199586.002.pdf > out2.txt | 17:58.15 |
| | the font arial is added to the global fonts folder, so ghostscript finds it ok | 17:58.42 |
| | when not embedded the degree symbol is replaced by infinity symbol, overlapping he next char | 17:59.12 |
| | when embedded it works fine | 17:59.21 |
| kens | Well ? You've specified EmbedAllFonts=false, so what did you expect ? | 17:59.21 |
| vv | not sure i understand, why woulld nto embedded result in replacing degree symbol with infinity symbol? | 17:59.48 |
| kens | Because of the way fonts work. If you don;t understand fonts, embedding and subsetting, then just embed the font. You should *always* embed CIDFonts in PDF files. | 18:00.30 |
| vv | for example when i do not include arial font, it substitutes it for its own Helvetica, and the degree symbol is fine. but i do nto want substitution, i want it to leave the font names as is | 18:00.44 |
| Robin_Watts | vv: You have a PDF that contains a font. The PDF says "put glyphs 1,2,3,4,5 on the page". | 18:01.20 |
| vv | this is only for extracting pages from pdf file, not for printing or mayhting, the new files will be used on other (windows) pc, so i want the font names stay exactly as they were in original file | 18:01.25 |
| Robin_Watts | glyph 5 in that font happens to be the degree symbol, so that's what you see. | 18:01.39 |
| | when you feed it into pdfwrite and DON'T embed the font, you are left with a pdf that still says "put glyphs 1,2,3,4,5" on the new page. | 18:02.10 |
| kens | You can try setting -dSubsetFonts=false | 18:02.16 |
| vv | let me try subsetfonts=false, just a sec | 18:02.33 |
| Robin_Watts | But the font it chooses to match with happens to have a different shape for glyph 5. | 18:02.34 |
| kens | Because that's almost certainly where the problem arises. But basically, embed the font | 18:02.35 |
| | Robin_Watts : I think the problem is its a CIDFont, which is not being embedded, but is being subset, so re-encoded. | 18:04.17 |
| vv | ok subsetfont=false did not help. It does nto subset the font, the font name is still Arial | 18:04.20 |
| | embedding greatly inscreases the size of pdf | 18:04.31 |
| kens | But to do any more I would have to see the file. And the bottom line is still 'embed the font' | 18:04.35 |
| vv | and yes embedding works | 18:04.38 |
| | just makes pdfs huge | 18:04.43 |
| kens | Right, so you have a solution | 18:04.44 |
| | And I'm off for dinner..... | 18:04.56 |
| chrisl | vv: how do you know gs finds Arial on your Linux system? | 18:06.11 |
| vv | it definitely does because it says so in the output, and also the font name in the pdf is not substituted to helvetica and is ttf | 18:06.41 |
| | when i removed arial font from folder, it substitutes it for helvetica | 18:06.54 |
| chrisl | Is it a TTF or a TrueType CIDFont? | 18:07.50 |
| vv | ttf font | 18:09.16 |
| | not cid | 18:09.17 |
| | from a standart windows 7 | 18:09.26 |
| chrisl | I mean what gets used in the PDF | 18:10.17 |
| vv | The pdf says Arial actual font ArialMT | 18:16.08 |
