API changes
===========
This file documents those API changes which affect
existing PDFlib client programs. Although I go to
some efforts in maintaining the existing API functions,
it is sometimes necessary to incorporate a few non-backward
compatible changes in order to streamline the API and
incorporate new or extended functions.
API changes in PDFlib V2.01
===========================
- PDF_place_inline_image() is no longer supported; use PDF_place_image()
instead (same interface):
Change
PDF_place_inline_image()
-- to --
PDF_place_image()
- PDF_put_image() is no longer required. Instead, the image data is
"parked" immediately on PDF_open_*():
Delete
PDF_put_image()
- PDF_execute_image() is no longer required. Instead, PDF_place_image()
can be called multiple times for a given PDF:
Change
PDF_execute_image()
-- to --
PDF_place_image()
- The interface and functionality of PDF_open_memory_image() changed:
Change
int PDF_open_memory_image(PDF *p, unsigned char *buffer,
int width, int height, int components, int bpc);
-- to --
int PDF_open_image(PDF *p, "raw", "memory", const char *data, long len,
int width, int height, int components, int bpc, NULL);
API changes in PDFlib V2.0
==========================
- All API functions with parameters of type "char *" changed to "const char *".
- change
PDF_data_source_from_buf()
-- to --
int PDF_open_memory_image(PDF *p, unsigned char *buffer,
int width, int height, int components, int bpc)
- change
PDF_set_text_matrix(PDF *p, PDF_matrix m);
-- to --
void PDF_set_text_matrix(PDF *p,
float a, float b, float c, float d, float e, float f);
- change
PDF_add_outline(p, text);
-- to --
PDF_add_bookmark(p, text, -1, 0);
- change
PDF_info *PDF_get_info(void);
-- to --
PDF_set_info(PDF *p, char *key, char *value);
(after PDF_new() and PDF_open_*())
- change
PDF_image->width and PDF_image->height
-- to --
PDF_get_image_width(PDF *p, PDF_image *image)
-- and --
PDF_get_image_height(PDF *p, PDF_image *image);
- change
PDF_info->error_handler = handler;
-- to --
PDF_new2(handler, ...);
Watch out for the changed signature of the error handler.
- change
void PDF_data_source_from_buf(*p, *src, buffer, len);
-- to --
PDF_image *PDF_open_memory_image(p, buffer, width, height, components, bpc);
void PDF_close_image(p, image);
- change
a4.width to a4_width etc.
- change
PDF_image image; /* for PDF_open_[GIF|JPEG|TIFF|memory_image] */
-- to --
int image;
- change
PDF_close_[GIF|JPEG|TIFF|memory_image];
-- to --
PDF_close_image();
- change
PDF_transition(p, type);
-- to --
PDF_transition(p, "type");
- change
PDF_set_font(p, fontname, size, encoding);
-- to --
int PDF_findfont(p, fontname, encoding, embed);
if (font == -1)
/* handle unavailable font */
PDF_setfont(p, font, size);
Note: the old PDF_set_font() is still available for compatibility.
- change
PDF_stringwidth(char *text);
-- to --
PDF_stringwidth(text, PDF_get_font(p), PDF_get_fontsize(p));
- change
PDF_open(filename);
-- to --
p = PDF_new();
if (PDF_open_file(filename) == -1) { ... }
-- or --
p = PDF_new();
if (PDF_open_fp(fp) == -1) { ... }
