It will be divided into 10 stripes of 500 pixels - each. The left and right 500 pixels of each stripe will - alternate black and white. The remaining part of the image will - have white stripes indicating 1 and black stripes indicating 0 - with the most-significant bit on top to indicate the page - number. In this way, every page will be unique and will consume - approximately 25 megabytes. Creating 200 pages like this will - make a file that is 5 GB. - - - The file will have to have object streams since a regular xref - table won't be able to support offsets that large. - - - A separate test program can create this file and do various - manipulations on it. This can be enabled with an environment - variable controlled by configure in much the same way image - comparison tests are enabled now. The argument to - --enable-large-file-test should be a path that has enough disk - space to do the tests, probably enough space for two coipes of - the file. The test program should also have an interactive mode - so we can generate the large file and then look at it with a - PDF viewer like Adobe Reader. The test suite should actually - read the file back in and look at all the page and stream - contents to make sure the file is really correct.
