Applications can use this functionality instead of + * gdk_pixbuf_new_from_file() or gdk_pixbuf_animation_new_from_file() + * when they need to parse image data in + * small chunks. For example, it should be used when reading an + * image from a (potentially) slow network connection, or when + * loading an extremely large file. + * + * + * To use #GdkPixbufLoader to load an image, just create a new one, and + * call gdk_pixbuf_loader_write() to send the data to it. When done, + * gdk_pixbuf_loader_close() should be called to end the stream and + * finalize everything. The loader will emit three important signals + * throughout the process. The first, #GdkPixbufLoader::size-prepared, + * will be emitted as soon as the image has enough information to + * determine the size of the image to be used. If you want to scale + * the image while loading it, you can call gdk_pixbuf_loader_set_size() + * in response to this signal. + * + * + * The second signal, #GdkPixbufLoader::area-prepared, will be emitted as + * soon as the pixbuf of the desired has been allocated. You can obtain it + * by calling gdk_pixbuf_loader_get_pixbuf(). If you want to use it, simply + * ref it. In addition, no actual information will be passed in yet, so the + * pixbuf can be safely filled with any temporary graphics (or an initial + * color) as needed. You can also call gdk_pixbuf_loader_get_pixbuf() later + * and get the same pixbuf. + * + * The last signal, #GdkPixbufLoader::area-updated, gets emitted every time + * a region is updated. This way you can update a partially completed image. + * Note that you do not know anything about the completeness of an image + * from the updated area. For example, in an interlaced image, you need to + * make several passes before the image is done loading. + * + * # Loading an animation + * + * Loading an animation is almost as easy as loading an image.

If gdk-pixbuf is built + * with the Sun mediaLib library, these functions are instead accelerated + * using mediaLib, which provides hardware acceleration on Intel, AMD, + * and Sparc chipsets.

But the coefficents depend on \(x_0\) and \(y_0\). +To simplify this a bit, define: +\[i_0 = \lfloor u(x_0,y_0) \rfloor = \lfloor {t_{00}x_0 + t_{01}y_0 + t_{02}} \rfloor \] +\[j_0 = \lfloor v(x_0,y_0) \rfloor = \lfloor {t_{10}x_0 + t_{11}y_0 + t_{12}} \rfloor \] +\[\Delta_u = u(x_0,y_0) - i_0 = t_{00}x_0 + t_{01}y_0 + t_{02} - \lfloor {t_{00}x_0 + t_{01}y_0 + t_{02}} \rfloor \] +\[\Delta_v = v(x_0,y_0) - j_0 = t_{10}x_0 + t_{11}y_0 + t_{12} - \lfloor {t_{10}x_0 + t_{11}y_0 + t_{12}} \rfloor \] +Then making the transforms \(x' = x - x_0\), \(y' = y - x_0\), \(i' = i - i_0\), \(j' = j - x_0\) +\begin{eqnarray*} +F(u,v) & = & F\left( {t_{00}x + t_{01}y + t_{02} - i \atop t_{10}x + t_{11}y + t_{12} - j} \right)\\ + & = & F\left( {t_{00}(x'+x_0) + t_{01}(y'+y_0) + t_{02} - (i'+i_0) \atop + t_{10}(x'+x_0) + t_{11}(y'+y_0) + t_{12} - (j'+j_0)} \right) \\ + & = & F\left( {\Delta_u + t_{00}x' + t_{01}y' - i' \atop + \Delta_v + t_{10}x' + t_{11}y' - j'} \right) +\end{eqnarray*} +Using that, we can then reparameterize the sums and integrals and +define coefficients that depend only on \((\Delta_u,\Delta_v)\), +which we'll call the \emph{phase} at the point \((x_0,y_0)\): +\[ +B_{x_0,y_0} = +\sum_{i = -\infty}^{\infty} \sum_{j = -\infty}^{\infty} A_{i_0+i,j_0+j} C_{i,j}(\Delta_u,\Delta_v) +\] +\[ +C_{i,j}(\Delta_u,\Delta_v) = +\int_{-\infty}^{\infty}\int_{-\infty}^{\infty} +F\left( {\Delta_u + t_{00}x + t_{01}y - i \atop + \Delta_v + t_{10}x + t_{11}y - j} \right) +G\left( {x \atop y} \right) dxdy +\] +\section{Separability} +A frequent special case is when the reconstruction and sampling functions +are of the form: +\[F(u,v) = f(u)f(v)\] +\[G(x,y) = g(x)g(y)\] +If we also have a transform that is purely a scale and translation; +(\(t_{10} = 0\), \(t_{01} = 0\)), then we can separate +\(C_{i,j}(\Delta_u,\Delta_v)\) into the product of a \(x\) portion +and a \(y\) portion: +\[C_{i,j}(\Delta_u,\Delta_v) = c_{i}(\Delta_u) c_{j}(\Delta_v)\] +\[c_{i}(\Delta_u) = \int_{-\infty}^{\infty} f(\Delta_u + t_{00}x - i)g(x)dx\] +\[c_{j}(\Delta_v) = \int_{-\infty}^{\infty} f(\Delta_v + t_{11}y - j)g(y)dy\] + +\section{Some filters} +gdk-pixbuf provides 4 standard filters for scaling, under the names ``NEAREST'', +``TILES'', ``BILINEAR'', and ``HYPER''.

In the \(x\) direction, for \(t_{00} < 1\), it is +the same as for ``TILES'': +\[f_u(t) = \cases{1, & if \(0 \le t \le 1\); \cr + 0, & otherwise}\] +\[g_u(t) = \cases{1, & if \(0 \le t \le 1\); \cr + 0, & otherwise}\] +but for \(t_{10} > 1\), we use bilinear reconstruction and delta-function +sampling: +\[f_u(t) = \cases{1 - |t - 0.5|, & if \(-0.5 \le t \le 1.5\); \cr + 0, & otherwise}\] +\[g_u(t) = \delta(t - 0.5)\] +The behavior in the \(y\) direction depends in the same way on \(t_{11}\). +\end{document} \ No newline at end of file diff --git a/libs/tk/ydk-pixbuf/pixops/pixops-internal.h b/libs/tk/ydk-pixbuf/pixops/pixops-internal.h new file mode 100644 index 0000000000..6497c2424d --- /dev/null +++ b/libs/tk/ydk-pixbuf/pixops/pixops-internal.h @@ -0,0 +1,23 @@ +/* + * Copyright (C) 2000 Red Hat, Inc + * + * This library is free software; you can redistribute it and/or + * modify it under the terms of the GNU Lesser General Public + * License as published by the Free Software Foundation; either + * version 2 of the License, or (at your option) any later version. + * + * This library is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

A Region is simply an area, as the name + * implies, and is implemented as a "y-x-banded" array of rectangles. To + * explain: Each Region is made up of a certain number of rectangles sorted + * by y coordinate first, and then by x coordinate. + * + * Furthermore, the rectangles are banded such that every rectangle with a + * given upper-left y coordinate (y1) will have the same lower-right y + * coordinate (y2) and vice versa. If a rectangle has scanlines in a band, it + * will span the entire vertical distance of the band. This means that some + * areas that could be merged into a taller rectangle will be represented as + * several shorter rectangles to account for shorter rectangles to its left + * or right but within its "vertical scope". + * + * An added constraint on the rectangles is that they must cover as much + * horizontal area as possible.

In this setup the + * GdkWindow (and other GdkDrawables) were platform independent classes, + * and the actual platform specific implementation was in a delegate + * object availible as "impl" in the window object. + * + * With the addition of client side windows and offscreen windows this + * changes a bit. The application-visible GdkWindow object behaves as + * it did before, but not all such windows now have a corresponding native + * window. Instead windows that are "client side" are emulated by the gdk + * code such that clipping, drawing, moving, events etc work as expected. + * + * For GdkWindows that have a native window the "impl" object is the + * same as before. However, for all client side windows the impl object + * is shared with its parent (i.e. all client windows descendants of one + * native window has the same impl. + * + * Additionally there is a new type of platform independent impl object, + * GdkOffscreenWindow. All windows of type GDK_WINDOW_OFFSCREEN get an impl + * of this type (while their children are generally GDK_WINDOW_CHILD virtual + * windows). Such windows work by allocating a GdkPixmap as the backing store + * for drawing operations, which is resized with the window. + * + * GdkWindows have a pointer to the "impl window" they are in, i.e. + * the topmost GdkWindow which have the same "impl" value. This is stored + * in impl_window, which is different from the window itself only for client + * side windows. + * All GdkWindows (native or not) track the position of the window in the parent + * (x, y), the size of the window (width, height), the position of the window + * with respect to the impl window (abs_x, abs_y). We also track the clip + * region of the window wrt parent windows and siblings, in window-relative + * coordinates with and without child windows included (clip_region, + * clip_region_with_children). + * + * All toplevel windows are native windows, but also child windows can be + * native (although not children of offscreens). We always listen to + * a basic set of events (see get_native_event_mask) for these windows + * so that we can emulate events for any client side children. + * + * For native windows we apply the calculated clip region as a window shape + * so that eg. client side siblings that overlap the native child properly + * draws over the native child window. + * + * In order to minimize flicker and for performance we use a couple of cacheing + * tricks. First of all, every time we do a window to window copy area, for instance + * when moving a client side window or when scrolling/moving a region in a window + * we store this in outstanding_moves instead of applying immediately. We then + * delay this move until we really need it (because something depends on being + * able to read it), or until we're handing a redraw from an expose/invalidation + * (actually we delay it past redraw, but before blitting the double buffer pixmap + * to the window). This gives us two advantages. First of all it minimizes the time + * from the window is moved to the exposes related to that move, secondly it allows + * us to be smart about how to do the copy. We combine multiple moves into one (when + * possible) and we don't actually do copies to anything that is or will be + * invalidated and exposed anyway. + * + * Secondly, we use something called a "implicit paint" during repaint handling. + * An implicit paint is similar to a regular paint for the paint stack, but it is + * not put on the stack. Instead, it is set on the impl window, and later when + * regular gdk_window_begin_paint_region() happen on a window of this impl window + * we reuse the pixmap from the implicit paint. During repaint we create and at the + * end flush an implicit paint, which means we can collect all the paints on + * multiple client side windows in the same backing store pixmap. + * + * All drawing to windows are wrapped with macros that set up the GC such that + * the offsets and clip region is right for drawing to the paint object or + * directly to the emulated window. It also automatically handles any flushing + * needed when drawing directly to a window. Adding window/paint clipping is + * done using _gdk_gc_add_drawable_clip which lets us efficiently add and then + * remove a custom clip region. + */ + +#ifndef __APPLE__ +#define USE_BACKING_STORE /* Appears to work on Win32, too, now. */ +#endif + +/* This adds a local value to the GdkVisibilityState enum */ +#define GDK_VISIBILITY_NOT_VIEWABLE 3 + +enum { + PICK_EMBEDDED_CHILD, /* only called if children are embedded */ + TO_EMBEDDER, + FROM_EMBEDDER, + LAST_SIGNAL +};
