Sometimes there is no output file produced or it may seem as though the software has quit working. This has to do with an invalid page range setting.
All of our products can convert one page, all pages or a page range. By default, they convert all pages. If you choose a page rage, you must reset it to all pages when done since the software remembers the last settings you used. If a conversion is attempted with an invalid page range, it will not produce a resulting file. It may seem as though it is not working. Once you go to “Options, Page” and adjust Page range to “All Pages””and re-attempt the conversion, you will produce a file.
If you want to edit the graphics in a PDF file in Microsoft Office or Visio, you’ll want to try pdf2picture. It operates in both vector and image mode and you can choose which is most appropriate at the time of conversion. Vector mode explodes the file into editable text and objects while image mode makes a high-fidelity copy of the file in an MS Office friendly format.
pdf2image is also available as a low cost option when you just need to use raster image formats. It is ideal for those who work on websites or printed publications like newsletters, brochures and customer bulletins.
To use the graphics produced by either pdf2image or pdf2picture in MS Office, you use Insert > Picture > From File… to add the converted graphics into your document. If you used vector mode (Windows Metafile WMF/EMF), you can now edit text and graphic elements using the Office drawing tools.
Note: Neither pdf2image or pdf2picture are for converting Word documents or reports heavy in text.
The software has been designed to be very easy to use and involves just a few simple steps:
- Select the PDF file you want to convert
- Change or customize settings by clicking on the Options button
- Change the name and location of the output file, if desired
If you are using a desktop product, there is a Help file included with the software. Just click on the Help button found in the bottom right corner of the software dialog. A new screen will open, with a table of content for all the available topics. You can expand the outline to find the section on Conversion Options or search the index using the Find command. Depending on which product you are using, there will be General Options, Page Options, Size Options and Format Specific Options.
For Developers – In the “docs” directory of the Conversion SDK installation, each option is explained in “options flysdk.pdf”. In addition to the description, for each option, the corresponding API function is listed.
rotate(0) STDAPI VgRotate(INT rotate)
rotate(0) Rotate the drawing using the angle specified. Default = 0, no rotation.
Converting multiple files is also called batch mode and all of our products support it. To specify more than one file, use the “Add” button. Once you have specified your first files, you can remove files and add files until you have the batch of files together that you want to convert.
When adding files, pdf2image, pdf2picture and pdf2cad will only display files with a .pdf extension. If the file you want to convert has a different extension, but you are sure that it is a PDF file, you should rename it to include a .pdf extension. PDF FLY is capable of digesting more input formats so it expects files with a .pdf, .ps, .eps or .prn extension.
If you do not need to edit the text, you can create a perfect vector object for each character. You can choose this by checking the “Convert Characters to Curves” option in the General tab of the Options menu. Every character will then be rendered with curves as a graphical representation of the character using the font information stored in the PDF. If a font was not embedded in the PDF, pdf2picture will refer to the /fonts/ directory in the pdf2picture installation folder. You can add Type 1 or TrueType font to this folder as needed to ensure a perfect match. To outline only specific fonts during conversion, email email@example.com for instructions.
If you do not need to edit the file at all, another option is to use the bitmap mode in pdf2picture or use pdf2image which creates a high-quality image of the file in four popular web and publishing formats..
After conversion, if you can not edit text, chances are that the text was already stored as graphics in the PDF original. It was probably converted to curves or plotted as pen strokes when the PDF file was created. It is no longer text, just vector curves that look like text. This often happens for example with PDF drawings are created from CAD, EDA or GIS applications as well as with print advertisements from a DTP-package to ensure font display accurately. Text is often converted to curves to ensure accurate print results and to protect against font incompatibilities. Once the text has been turned into curves, there is no way for pdf2picture to retrieve it as real text. If the text is still searchable in the PDF file, we can produce it as editable text in the conversion output.
Tip: To see if the text is searchable and convertable or not, open your PDF file in Acrobat Reader and try to “Select” some text. If you can mark it, you can convert it.
pdf2image is perfect for the job since it outputs PNG, the native format for MusicPad. By setting the width for conversion at 600 pixels, you can generate a file which will be accepted using the MusicPad Pro import feature. It can be used to convert any PDF music file.
PNG is the native format of the MusicPad Manager so you would first need to use pdf2image to convert all your music to this format. Once you have generated all of the PNG’s, you should be able to import them directly by opening the MusicPad Manager application. Then just select File/Import.
MusicPad Pro expects the files that are imported to be 600×800. This can be set by choosing width = 600 pixels under the “Options” button during conversion in pdf2image.
If you have any trouble converting your music, please email a sample PDF file to firstname.lastname@example.org and we will return it to you in PNG format ready to import along with any special settings that you need to select.
There are two important issues at play here.
First – make sure you choose the correct image format for your file type. If your PDF file is mostly text, you should choose GIF or PNG since they render images with few colors sharply. JPEG is better suited for photographic images which use many colors.
The second consideration is resolution or “dots per inch” (dpi). The resolution you choose determines the quality (and the size) of the output. Although a high resolution will yield a super-sharp image, it will also product a large file size which may impact performance. The rule of thumb is to use the lowest resolution which delivers the quality you need. Some guidelines are:
- For screen display (web or office) – use 96dpi.
- For images that will be printed on laser or inkjet printers – use 150 dpi
- For images that will be printed professionally – use 300 dpi
If you want to adjust the resolution, simply increase the dpi setting in the Options menu.
The font glyphs of the 13 standard PostScript fonts are included.
If you need to convert to an image format or the text to curves/polys (= emulate) in a vector format either the font must be one of the 13 standard fonts or the font should be embedded within the PDF or PostScript file. Contact email@example.com if you want to add font glyphs.
13 Standard PostScript fonts:
- The image formats used on web sites are JPEG (or JPG), PNG and GIF. JPEG is best for images with many colors such as photos. GIF is best for line art, illustrations and drawings with limited color. PNG is the most versatile and can be used quite broadly on web-sites.
- The image formats used in documents follow a similar rule. GIF, TIFF and PNG are best for images with fewer colors and JPEG is used for images with many colors such as photos. The best test is to use pdf2image to convert to a few different formats and then view them both on-screen and in print to see which gives you the desired result.
- It’s also important to determine what formats your application can import. If the program you want to use only accepts BMP, then you need to convert to this format, even if it produces larger files than PNG.
- If you are generating images for use on web sites, convert at 72 dpi (dots per inch) or 96 dpi. These settings match screen resolution pixel for pixel for the best match and sharpest display.
- For general office printing, choose 150 dpi. This will generate a crisp image with the smallest file size.
- For office publishing and high quality laser printing, choose 300 dpi. The files will be larger but the images will be very clear.
- For professional printing, choose 300 dpi – 1200 dpi. It’s best to ask your printer who will recommend the best resolution to match his equipment.
