Store the given texture in memory as a PNG file. Use gdk_texture_new_from_bytes() to read it back. If you want to serialize a texture, this is a convenient and portable way to do that. If you need more control over the generated image, such as attaching metadata, you should look into an image handling library such as the gdk-pixbuf library.

GDK provides a number of threadsafe texture loading functions: gdk_texture_new_from_resource(), gdk_texture_new_from_bytes(), gdk_texture_new_from_file(), gdk_texture_new_from_filename(), gdk_texture_new_for_pixbuf(). Note that these are meant for loading icons and resources that are shipped with the toolkit or application.

Saves pixbuf to a file in format type. By default, “jpeg”, “png”, “ico” and “bmp” are possible file formats to save in, but more formats may be installed. The list of all writable formats can be determined in the following way: If error is set, FALSE will be returned.

2013年1月3日 · Using GTK+ 3.6 I would like to display an image from a buffer in memory, not a file on disk. I have a const char *data with the image data, and I'm trying to create a GTK image from it. So far I have tried two approaches which I thought could work. Both use GdkPixbuf, and thus require the image data to be guchar* (unsigned char*).

2013年8月9日 · Gdk::Pixbuf是GTK库极为重要的一个组件，从图标到图像控件，到处都可以看到它的身影，Gdk::Pixbuf让GTK使用图像资源变得轻松许多。 Gdk::Pixbuf的用法文档说的比较清楚了，就不再重复，值得注意的是，Pixbuf在内部如何存储图像文档并未详细说明，这会给使用带来一 …

2009年10月30日 · gdk_pixbuf_new_from_file()-- but see unwind's answer for a better way to do it using a GtkImage widget. You need to set the background pixmap field in the widget's style structure:

2016年10月9日 · How can I save the current window as an image file such as a png? I know I can get a gdkWindow from current windows. I can even get an image. From this image struct I can even query each pixel. But from what I understand what I really need is to get a pixbuf. int width; int height; this.GetSize(width, height); this.GdkWindow.GetImage(0,0,width ...

Store the given texture in memory as a PNG file. Use new_from_bytes() to read it back. If you want to serialize a texture, this is a convenient and portable way to do that.

Then I use gdk_pixbuf_loader_new_with_type("png", &error); and I got: Image type “png” is not supported. I added the functions gdk_pixbuf_get_formats() and gdk_pixbuf_format_get_name() to get the supported formats, and I only got two: wmf and emf. I have tried updating the gdk-pixbuf loaders using gdk-pixbuf-query-loaders --update-cache

gtk.Image is a subclass of gtk.Misc, which implies that you can align it (center, left, right) and add padding to it, using gtk.Misc methods. gtk.Image is a “no window” widget (has no gdk.Window of its own), so by default does not receive events.
