File search and the SearchPath resource category. PDFlib reads a variety of data items, such as raster images, font outline and metrics information, encoding definitions, PDF documents, and ICC color profiles from disk files. In addition to relative or absolute path names you can also use file names without any path specification. The SearchPath resource category can be used to specify a list of path names for directories containing the required data files. When PDFlib must open a file it will first use the file name exactly as supplied and try to open the file. If this attempt fails, PDFlib will try to open the file in the directories specified in the SearchPath resource category one after another until it succeeds. SearchPath entries can be accumulated, and will be searched in reverse order (paths set at a later point in time will searched before earlier ones). This feature can be used to free PDFlib applications from platform-specific file system schemes. You can set search path entries as follows: p.set_parameter("SearchPath", "/path/to/dir1"); p.set_parameter("SearchPath", "/path/to/dir2"); In order to disable the search you can use a fully specified path name in the PDFlib functions. Note the following platform-specific features of the SearchPath resource category: > On Windows PDFlib will initialize the SearchPath with entries from the registry. The following registry entries may contain a list of path names separated by a semicolon ’;’ character. They will be searched in the order provided below: HKLM\SOFTWARE\PDFlib\PDFlib8\8.0.6\SearchPath HKLM\SOFTWARE\PDFlib\PDFlib8\SearchPath HKLM\SOFTWARE\PDFlib\SearchPath > The COM and .NET installer will initialize the SearchPath registry entry with the following directory (or a similar one if you installed PDFlib elsewhere): C:\Program Files\PDFlib\PDFlib 8.0.6\resource Sample UPR file. The following listing gives an example of a UPR configuration file: PS-Resources-1.0 . SearchPath /usr/local/lib/fonts C:/psfonts/pfm C:/psfonts /users/kurt/my_images . FontAFM Code-128=Code_128.afm . FontPFM Corporate-Bold=corpb___.pfm Mistral=c:/psfonts/pfm/mist____.pfm . FontOutline Code-128=Code_128.pfa ArialMT=Arial.ttf . HostFont Wingdings=Wingdings . Encoding 64 Chapter 3: Creating PDF Documents (Edition for COM, .NET, and REALbasic)
myencoding=myencoding.enc . ICCProfile highspeedprinter=cmykhighspeed.icc . Searching for the UPR resource file. If only the built-in resources (e.g., PDF core font, built-in encodings, sRGB ICC profile) or system resources (host fonts) are to be used, a UPR configuration file is not required since PDFlib will find all necessary resources without any additional configuration. If other resources are to be used you can specify such resources via calls to set_ parameter( ) (see below) or in a UPR resource file. PDFlib reads this file automatically when the first resource is requested. The detailed process is as follows: > If the environment variable PDFLIBRESOURCE is defined PDFlib takes its value as the name of the UPR file to be read. If this file cannot be read an exception will be thrown. > If the environment variable PDFLIBRESOURCE is not defined PDFlib tries to open a file with the following name: pdflib.upr If this file cannot be read no exception will be thrown. > On Windows PDFlib will additionally try to read the following registry entries which will be searched in the order provided below: HKLM\Software\PDFlib\PDFlib8\8.0.6\resourcefile HKLM\Software\PDFlib\PDFlib8\resourcefile HKLM\Software\PDFlib\resourcefile The values of these entries will be taken as the name of the resource file to be used. If this file cannot be read an exception will be thrown. Be careful when manually accessing the registry on 64-bit Windows systems: as usual, 64-bit PDFlib binaries will work with the 64-bit view of the Windows registry, while 32-bit PDFlib binaries running on a 64-bit system will work with the 32-bit view of the registry. If you must add registry keys for a 32-bit product manually, make sure to use the 32-bit version of the regedit tool. It can be invoked as follows from the Start, Run... dialog: %systemroot%\syswow64\regedit > The client can force PDFlib to read a resource file at runtime by explicitly setting the resourcefile parameter: p.set_parameter("resourcefile", "/path/to/pdflib.upr"); This call can be repeated arbitrarily often; the resource entries will be accumulated. Configuring resources at runtime. In addition to using a UPR file for the configuration, it is also possible to directly configure individual resources within the source code via the set_parameter( ) function. This function takes a category name and a corresponding resource entry as it would appear in the respective section of this category in a UPR resource file, for example: p.set_parameter("FontAFM", "Foobar-Bold=foobb___.afm"); p.set_parameter("FontOutline", "Foobar-Bold=foobb___.pfa"); 3.1 General PDFlib Programming Aspects 65
