Description
|
|
Packit |
a4058c |
These functions allow to save a GdkPixbuf in a number of
|
|
Packit |
a4058c |
file formats. The formatted data can be written to a file
|
|
Packit |
a4058c |
or to a memory buffer. GdkPixBuf can also call a user-defined
|
|
Packit |
a4058c |
callback on the data, which allows to e.g. write the image
|
|
Packit |
a4058c |
to a socket or store it in a database.

Currently only few parameters exist. JPEG images can be saved with a
|
|
Packit |
a4058c |
"quality" parameter; its value should be in the range [0,100]. JPEG
|
|
Packit |
a4058c |
and PNG density can be set by setting the "x-dpi" and "y-dpi" parameters
|
|
Packit |
a4058c |
to the appropriate values in dots per inch.
|
|
Packit |
a4058c |
Text chunks can be attached to PNG images by specifying parameters of
|
|
Packit |
a4058c |
the form "tEXt::key", where key is an ASCII string of length 1-79.
|
|
Packit |
a4058c |
The values are UTF-8 encoded strings. The PNG compression level can
|
|
Packit |
a4058c |
be specified using the "compression" parameter; it's value is in an
|
|
Packit |
a4058c |
integer in the range of [0,9].
|
|
Packit |
a4058c |
ICC color profiles can also be embedded into PNG, JPEG and TIFF images.
|
|
Packit |
a4058c |
The "icc-profile" value should be the complete ICC profile encoded
|
|
Packit |
a4058c |
into base64.

TIFF images recognize: (1) a "bits-per-sample" option (integer) which
|
|
Packit |
a4058c |
can be either 1 for saving bi-level CCITTFAX4 images, or 8 for saving

8-bits per sample; (2) a "compression" option (integer) which can be
|
|
Packit |
a4058c |
1 for no compression, 2 for Huffman, 5 for LZW, 7 for JPEG and 8 for
|
|
Packit |
a4058c |
DEFLATE (see the libtiff documentation and tiff.h for all supported

|
Packit |

codec values); (3) an "icc-profile" option (zero-terminated string)
