## Includes

    #include <gdk-pixbuf/gdk-pixbuf.h>

## Description

These macros and variables let you check the version of gdk-pixbuf you're linking against.

## Functions

## Types and Values

### gdk_pixbuf_version

    extern const char *gdk_pixbuf_version;

Contains the full version of the gdk-pixbuf library as a string. This is the version currently in use by a running program.

### gdk_pixbuf_major_version

    extern const guint gdk_pixbuf_major_version;

The major version number of the gdk-pixbuf library. (e.g. in gdk-pixbuf version 1.2.5 this is 1.)

This variable is in the library, so represents the gdk-pixbuf library you have linked against. Contrast with the GDK_PIXBUF_MAJOR macro, which represents the major version of the gdk-pixbuf headers you have included.

### gdk_pixbuf_minor_version

    extern const guint gdk_pixbuf_minor_version;

The minor version number of the gdk-pixbuf library. (e.g. in gdk-pixbuf version 1.2.5 this is 2.)

This variable is in the library, so represents the gdk-pixbuf library you have linked against. Contrast with the GDK_PIXBUF_MINOR macro, which represents the minor version of the gdk-pixbuf headers you have included.

### gdk_pixbuf_micro_version

    extern const guint gdk_pixbuf_micro_version;

The micro version number of the gdk-pixbuf library. (e.g. in gdk-pixbuf version 1.2.5 this is 5.)

This variable is in the library, so represents the gdk-pixbuf library you have linked against. Contrast with the GDK_PIXBUF_MICRO macro, which represents the micro version of the gdk-pixbuf headers you have included.

### GDK_PIXBUF_VERSION

    #define GDK_PIXBUF_VERSION "2.36.9"

### GDK_PIXBUF_VERSION_MIN_REQUIRED

    #define GDK_PIXBUF_VERSION_MIN_REQUIRED (GDK_PIXBUF_VERSION_CUR_STABLE)

A macro that should be defined by the user prior to including the gdk-pixbuf.h header. The definition should be one of the predefined version macros: `GDK_PIXBUF_VERSION_2_0`, `GDK_PIXBUF_VERSION_2_2`, ...

This macro defines the lower bound for the GdkPixbuf API to use.

If a function has been deprecated in a newer version of GdkPixbuf, defining this symbol hides the compiler warnings for those functions without disabling warnings for the other deprecated functions.

<warning> Warning: if you define this macro, do not forget to update it! Especially when writing new code. Otherwise you can miss the new deprecations. </warning>

Since: 2.36

### GDK_PIXBUF_VERSION_MAX_ALLOWED

    #define GDK_PIXBUF_VERSION_MAX_ALLOWED  GDK_PIXBUF_VERSION_MIN_REQUIRED

A macro that should be defined by the user prior to including the gdk-pixbuf.h header. The definition should be one of the predefined version macros: `GDK_PIXBUF_VERSION_2_0`, `GDK_PIXBUF_VERSION_2_2`, ...

This macro defines the upper bound for the GdkPixbuf API to use.

If a function has been introduced in a newer version of GdkPixbuf, it is possible to use this symbol to get compiler warnings when trying to use that function.
