Images and Text in PDF files
PDF files can contain any type of file, just as an email can have attachments. File Juicer can extract most of the bitmap images.
File Juicer can also extract PDF which are embedded in other files.
JPEG
Compressed images are stored in PDF as embedded JPEG files which can be extracted.EPS and PostScript
Are converted to PDF the same way Preview does before they are "Juiced".Losslessly compressed images
File Juicer extract them as PDF to preserve the ICC color information with the file.Vector Graphics
Is an integrated part of the PDF files, and there is no boundary between text and graphics. To extract vector graphics from a PDF, you can use Tiger & Preview which let you place a crop and copy the contents to a new PDF.
One exception is if an EPS file is embedded in a Word document and then printed to PDF. File Juicer can extract the EPS from this PDF.
Text
File Juicer can extract the text both as plain text and as RTF if you have Mac OS 10.4. In the plain text case, you enable the "ascii" checkbox in the preferences. Note that the encoding of the extracted text is UTF-8 which preserve the "exotic" characters which can be found in PDF files. TextEdit understand UTF-8 if you chose it in the preferences.
RTF can also be a good format if you wish to convert simple PDF files to Word.
Scanned Text
If you have a scanned document, File Juicer can extract the images from it, but it does not convert the images to text. You need an Optical Characther Recognition application.
ICC profiles
PDF files may result in File Juicer finding ICC profiles. They are stored separate from the images but when File Juicer saves images from PDF, it will include the ICC profiles correctly.
