| 70 | * Page Structure of the Generated PDF: |
| 71 | * |
| 72 | * Each page requiring fallbacks images contains a knockout group at |
| 73 | * the top level. The first operation of the knockout group paints a |
| 74 | * group containing all the supported drawing operations. Fallback |
| 75 | * images (if any) are painted in the knockout group. This ensures |
| 76 | * that fallback images do not composite with any content under the |
| 77 | * fallback images. |
| 78 | * |
| 79 | * Streams: |
| 80 | * |
| 81 | * This PDF surface has three types of streams: |
| 82 | * - PDF Stream |
| 83 | * - Content Stream |
| 84 | * - Group Stream |
| 85 | * - Object stream |
| 86 | * |
| 87 | * Calling _cairo_output_stream_printf (surface->output, ...) will |
| 88 | * write to the currently open stream. |
| 89 | * |
| 90 | * PDF Stream: |
| 91 | * A PDF Stream may be opened and closed with the following functions: |
| 92 | * _cairo_pdf_surface_open stream () |
| 93 | * _cairo_pdf_surface_close_stream () |
| 94 | * |
| 95 | * PDF Streams are written directly to the PDF file. They are used for |
| 96 | * fonts, images and patterns. |
| 97 | * |
| 98 | * Content Stream: |
| 99 | * The Content Stream is opened and closed with the following functions: |
| 100 | * _cairo_pdf_surface_open_content_stream () |
| 101 | * _cairo_pdf_surface_close_content_stream () |
| 102 | * |
| 103 | * The Content Stream contains the text and graphics operators. |
| 104 | * |
| 105 | * Group Stream: |
| 106 | * A Group Stream may be opened and closed with the following functions: |
| 107 | * _cairo_pdf_surface_open_group () |
| 108 | * _cairo_pdf_surface_close_group () |
| 109 | * |
| 110 | * A Group Stream is a Form XObject. It is used for short sequences |
| 111 | * of operators. As the content is very short the group is stored in |
| 112 | * memory until it is closed. This allows some optimization such as |
| 113 | * including the Resource dictionary and stream length inside the |
| 114 | * XObject instead of using an indirect object. |
| 115 | * |
| 116 | * Object Stream (PDF 1.5) |
| 117 | * An Object Stream may be opened and closed with the following functions: |
| 118 | * _cairo_pdf_surface_open_object_stream () |
| 119 | * _cairo_pdf_surface_close_object_stream () |
| 120 | * |
| 121 | * An Object Stream contains one or more objects compressed into a stream. |
| 122 | * Only non stream objects are permitted. When emitting objects intended for |
| 123 | * the Object Stream, enclose the emit object operation with |
| 124 | * _cairo_pdf_surface_object_begin()/_cairo_pdf_surface_object_end(). |

| 128 | * SECTION:cairo-pdf |
| 129 | * @Title: PDF Surfaces |
| 130 | * @Short_Description: Rendering PDF documents |
| 131 | * @See_Also: #cairo_surface_t |
| 132 | * |
| 133 | * The PDF surface is used to render cairo graphics to Adobe |
| 134 | * PDF files and is a multi-page vector surface backend. |
| 135 | * |
| 136 | * The following mime types are supported on source patterns: |
| 137 | * %CAIRO_MIME_TYPE_JPEG, %CAIRO_MIME_TYPE_JP2, |
| 138 | * %CAIRO_MIME_TYPE_UNIQUE_ID, %CAIRO_MIME_TYPE_JBIG2, |
| 139 | * %CAIRO_MIME_TYPE_JBIG2_GLOBAL, %CAIRO_MIME_TYPE_JBIG2_GLOBAL_ID, |
| 140 | * %CAIRO_MIME_TYPE_CCITT_FAX, %CAIRO_MIME_TYPE_CCITT_FAX_PARAMS. |
| 141 | * |
| 142 | * # JBIG2 Images # |
| 143 | * JBIG2 data in PDF must be in the embedded format as described in |
| 144 | * ISO/IEC 11544. Image specific JBIG2 data must be in |
| 145 | * %CAIRO_MIME_TYPE_JBIG2. Any global segments in the JBIG2 data |
| 146 | * (segments with page association field set to 0) must be in |
| 147 | * %CAIRO_MIME_TYPE_JBIG2_GLOBAL. The global data may be shared by |
| 148 | * multiple images. All images sharing the same global data must set |
| 149 | * %CAIRO_MIME_TYPE_JBIG2_GLOBAL_ID to a unique identifier. At least |
| 150 | * one of the images must provide the global data using |
| 151 | * %CAIRO_MIME_TYPE_JBIG2_GLOBAL. The global data will only be |
| 152 | * embedded once and shared by all JBIG2 images with the same |
| 153 | * %CAIRO_MIME_TYPE_JBIG2_GLOBAL_ID. |
| 154 | * |
| 155 | * # CCITT Fax Images # {#ccitt} |
| 156 | * The %CAIRO_MIME_TYPE_CCITT_FAX mime data requires a number of decoding |
| 157 | * parameters These parameters are specified using %CAIRO_MIME_TYPE_CCITT_FAX_PARAMS. |
| 158 | * |
| 159 | * %CAIRO_MIME_TYPE_CCITT_FAX_PARAMS mime data must contain a string of the form |
| 160 | * "param1=value1 param2=value2 ...". |
| 161 | * |
| 162 | * @Columns: [required] An integer specifying the width of the image in pixels. |
| 163 | * |
| 164 | * @Rows: [required] An integer specifying the height of the image in scan lines. |
| 165 | * |
| 166 | * @K: [optional] An integer identifying the encoding scheme used. < 0 |
| 167 | * is 2 dimensional Group 4, = 0 is Group3 1 dimensional, > 0 is mixed 1 |
| 168 | * and 2 dimensional encoding. Default is 0. |
| 169 | * |
| 170 | * @EndOfLine: [optional] If true end-of-line bit patterns are present. Default is false. |
| 171 | * |
| 172 | * @EncodedByteAlign: [optional] If true the end of line is padded |
| 173 | * with 0 bits so the next line begins on a byte boundary. Default is false. |
| 174 | * |
| 175 | * @EndOfBlock: [optional] If true the data contains an end-of-block pattern. Default is true. |
| 176 | * |
| 177 | * @BlackIs1: [optional] If true 1 bits are black pixels. Default is false. |
| 178 | * |
| 179 | * @DamagedRowsBeforeError: [optional] An integer specifying the |
| 180 | * number of damages rows tolerated before an error occurs. Default is 0. |
| 181 | * |
| 182 | * Boolean values may be "true" or "false", or 1 or 0. |
| 183 | * |
| 184 | * These parameters are the same as the CCITTFaxDecode parameters in the |
| 185 | * [PostScript Language Reference](https://www.adobe.com/products/postscript/pdfs/PLRM.pdf) |
| 186 | * and [Portable Document Format (PDF)](https://www.adobe.com/content/dam/Adobe/en/devnet/pdf/pdfs/PDF32000_2008.pdf). |
