Bitmap

Description Pixmaps are offscreen drawables. They can be drawn upon with the standard drawing primitives, then copied to another drawable (such as a GdkWindow) with gdk_pixmap_draw(). The depth of a pixmap is the number of bits per pixels. Bitmaps are simply pixmaps with a depth of 1. (That is, they are monochrome bitmaps - each pixel can be either on or off). GTK 3 will remove GdkPixmap and GdkBitmap. You should use cairo surfaces instead. However, because a lot of functions still use these types, they are not deprecated.

class Bitmap {

protected

GdkBitmap* gdkBitmap;

GdkBitmap* getBitmapStruct();

void* getStruct();

this(GdkBitmap* gdkBitmap);

static Bitmap createFromData(Drawable drawable, string data, int width, int height);

}

Constructors

this this(GdkBitmap* gdkBitmap): Sets our main struct and passes it to the parent class

Static functions

createFromData Bitmap createFromData(Drawable drawable, string data, int width, int height): Warning gdk_bitmap_create_from_data has been deprecated since version 2.22 and should not be used in newly-written code. You can create a Cairo image surface using cairo_image_surface_create_for_data() instead. Specify CAIRO_FORMAT_A1 as the format to get a bitmap. Keep in mind that Cairo images must have a rowstride of 4 bytes, so you will need to align your data properly. If you must use a pixmap, use gdk_pixmap_new() with a depth of 1 to create a bitmap and then use gdk_cairo_create(), cairo_set_source_surface() and cairo_paint() to draw the image surface to the bitmap. Creates a new bitmap from data in XBM format.
