| 55 * @description: | |
| 56 * Open a new stream to parse LZW-compressed font files. This is | |
| 57 * mainly used to support the compressed `*.pcf.Z' fonts that come | |
| 58 * with XFree86. | |
| 59 * | |
| 60 * @input: | |
| 61 * stream :: The target embedding stream. | |
| 62 * | |
| 63 * source :: The source stream. | |
| 64 * | |
| 65 * @return: | |
| 66 * FreeType error code. 0~means success. | |
| 67 * | |
| 68 * @note: | |
| 69 * The source stream must be opened _before_ calling this function. | |
| 70 * | |
| 71 * Calling the internal function `FT_Stream_Close' on the new stream will | |
| 72 * *not* call `FT_Stream_Close' on the source stream. None of the stream | |
| 73 * objects will be released to the heap. | |
| 74 * | |
| 75 * The stream implementation is very basic and resets the decompression | |
| 76 * process each time seeking backwards is needed within the stream | |
| 77 * | |
| 78 * In certain builds of the library, LZW compression recognition is | |
| 79 * automatically handled when calling @FT_New_Face or @FT_Open_Face. | |
| 80 * This means that if no font driver is capable of handling the raw | |
| 81 * compressed file, the library will try to open a LZW stream from it | |
| 82 * and re-open the face with it. | |
| 83 * | |
| 84 * This function may return `FT_Err_Unimplemented_Feature' if your build | |
| 85 * of FreeType was not compiled with LZW support. | |
