GdkPixbuf * gimp_image_get_thumbnail (gint32 image_ID, gint width, gint height, GimpPixbufTransparency alpha);
Retrieves a thumbnail pixbuf for the image identified by image_ID. The thumbnail will be not larger than the requested size.
image_ID : | the image ID |
width : | the requested thumbnail width (<= 1024 pixels) |
height : | the requested thumbnail height (<= 1024 pixels) |
alpha : | how to handle an alpha channel |
Returns : | a new GdkPixbuf |
Since GIMP 2.2
GdkPixbuf * gimp_drawable_get_thumbnail (gint32 drawable_ID, gint width, gint height, GimpPixbufTransparency alpha);
Retrieves a thumbnail pixbuf for the drawable identified by drawable_ID. The thumbnail will be not larger than the requested size.
drawable_ID : | the drawable ID |
width : | the requested thumbnail width (<= 1024 pixels) |
height : | the requested thumbnail height (<= 1024 pixels) |
alpha : | how to handle an alpha channel |
Returns : | a new GdkPixbuf |
Since GIMP 2.2
GdkPixbuf * gimp_drawable_get_sub_thumbnail (gint32 drawable_ID, gint src_x, gint src_y, gint src_width, gint src_height, gint dest_width, gint dest_height, GimpPixbufTransparency alpha);
Retrieves a thumbnail pixbuf for the drawable identified by drawable_ID. The thumbnail will be not larger than the requested size.
drawable_ID : | the drawable ID |
src_x : | the x coordinate of the area |
src_y : | the y coordinate of the area |
src_width : | the width of the area |
src_height : | the height of the area |
dest_width : | the requested thumbnail width (<= 1024 pixels) |
dest_height : | the requested thumbnail height (<= 1024 pixels) |
alpha : | how to handle an alpha channel |
Returns : | a new GdkPixbuf |
Since GIMP 2.2
gint32 gimp_layer_new_from_pixbuf (gint32 image_ID, const gchar *name, GdkPixbuf *pixbuf, gdouble opacity, GimpLayerModeEffects mode, gdouble progress_start, gdouble progress_end);
Create a new layer from a GdkPixbuf.
This procedure creates a new layer from the given GdkPixbuf. The image has to be an RGB image and just like with gimp_layer_new() you will still need to add the layer to it.
If you pass progress_end > progress_start to this function, gimp_progress_update() will be called for. You have to call gimp_progress_init() beforehand then.
image_ID : | The RGB image to which to add the layer. |
name : | The layer name. |
pixbuf : | A GdkPixbuf. |
opacity : | The layer opacity. |
mode : | The layer combination mode. |
progress_start : | start of progress |
progress_end : | end of progress |
Returns : | The newly created layer. |
Since GIMP 2.4
