How is it possible to determine the fonts used by text in PDF and TIFF files?
|
For TIFFs or any other raster (pixel) image, Jin's answer covers it. For PDFs (assuming it's a 'proper' PDF and not a raster image embedded in a PDF, as produced by scanning/fax software), font information is embedded in the file. In Adobe Reader 8 -- probably slightly different in other applications -- File menu > Properties > Fonts tab gives you a list of all fonts used in the document. I'm pretty sure Adobe Acrobat allows you to check the font of a selected piece of text, but I don't have it to hand. There are also third-party plugins for Acrobat, such as Enfocus PitStop Pro, which add the ability to find/replace/report on instances of a particular font throughout a document. |

If you need help identifying a font sample, there are lots of resources. Some are automated, you submit a sample screenshot or go through a series of questions that help narrow the possibilities:
Some software can help find a font that's close to what you want: Others are human-driven, where experts and enthusiasts may examine your submission: Finally, there are services and programs designed to simply help you choose an appropriate font for a given use: |

In a PDF with actual text, you can copy a block of text into Word (or another rich editor) and look at the Font dropdown. |

Just to add to the list a new software to identify fonts using an image or screen capture: "Find my Font" - http://www.findmyfont.com (I'm the developer of this software). The application runs on either Mac-OS or Windows and identifies the fonts of a given bitmap image by searching for fonts both online (70.000+ fonts) and on your computer while you are given a list of exact and similar matches + a % match for each one, in just 5-10 secs. It can use all kinds of color images without extra pre-processing. |
