Maybe I am having the same question as you do. I am trying to display a 24bit
image with size 2048X2048 pixels, and following is my code:
//create a GdkPixbuf
GdkPixbuf* pb = gdk_pixbuf_new_from_data( pDisplayBuf, // data buffer
GDK_COLORSPACE_RGB, //COLORSPACE
FALSE, // has_alpha,
8, // int bits_per_sample,
2048, // int width,
2048, // int height,
2048*3, // sizeX*3; //int rowstride,
NULL, //GdkPixbufDestroyNotify destroy_fn,
NULL //gpointer destroy_fn_data);
);
//display img
GtkWidget* img = lookup_widget(MainWnd, "image1");
gtk_image_set_from_pixbuf(GTK_IMAGE(img), //GtkImage *image,
pb// GdkPixbuf *pixbuf
);
the results i got is that: the image did appear, but the sizes are shrinked
as 684 X 684 , and there are THREE same images tile in the viewport, the
first and last ones are clipped.
Can anyone tell me how to fix this? thanks!!
