= module Gdk::RGB
- Gdk::RGB converts RGB, grayscale, and colormapped images into the native window pixel format and displays them. It takes care of colormaps, visuals, dithering, and management of the temporary buffers.
+ ((<Gdk::RGB>)) converts RGB, grayscale, and colormapped images into the native window pixel format and displays them. It takes care of colormaps, visuals, dithering, and management of the temporary buffers.
== Module Methods
- --- Gdk::RGB.cmap()
- Retrieves colormap set by Gdk::RGB.
- * Returns: The Gdk::Colormap set by Gdk::RGB.
+ --- Gdk::RGB.colormap
+ Retrieves colormap set by ((<Gdk::RGB>)).
+ * Returns: The Gdk::Colormap set by ((<Gdk::RGB>)).
- --- Gdk::RGB.visual()
+ --- Gdk::RGB.visual
Retrieves visual set by Gdk::RGB.
* Returns: The Gdk::Visual chosen by Gdk::RGB.
--- Gdk::RGB.draw_rgb_image(win, gc, x, y, w, h, dither, buf, rowstride)
Draws a rectangular RGB image in the Gdk::Drawable.
* win: The Gdk::Drawable to draw in (usually a Gdk::Window).
- * gc: The Gdk::GC graphics context to control the drawing style.
+ * gc: The ((<Gdk::GC>)) graphics context to control the drawing style.
* x: The x coordinate of the top-left corner of the rectangle in the drawable.
* y: The y coordinate of the top-left corner of the rectangle in the drawable.
* w: The width of the rectangle to be drawn.
* h: The height of the rectangle to be drawn.
- * dither: A GdkRgbDither value, selecting the desired dither mode.
+ * dither: A ((<GdkRgbDither|Gdk::RGB#GdkRgbDither>)) value, selecting the desired dither mode.
* buf: The 24-bit pixel data.
* rowstride: The number of bytes from the start of one row in buf to the start of the next.
* Returns: self
--- Gdk::RGB.draw_rgb_image_dithalign(win, gc, x, y w, h, dither, buf, rowstride, xdith, ydith)
Draws an RGB image in the Gdk::Drawable, with an adjustment for dither alignment. This function is useful when drawing dithered images into a window that may be scrolled. Pixel (x, y) will be drawn dithered as if its actual location is (x + xdith, y + ydith). Thus, if you draw an image into a window using zero dither alignment, then scroll up one pixel, subsequent draws to the window should have ydith = 1.
* win: The Gdk::Drawable to draw in (usually a Gdk::Window).
- * gc: The Gdk::GC graphics context to control the drawing style.
+ * gc: The ((<Gdk::GC>)) graphics context to control the drawing style.
* x: The x coordinate of the top-left corner of the rectangle in the drawable.
* y: The y coordinate of the top-left corner of the rectangle in the drawable.
* w: The width of the rectangle to be drawn.
* h: The height of the rectangle to be drawn.
- * dither: A GdkRgbDither value, selecting the desired dither mode.
+ * dither: A ((<GdkRgbDither|Gdk::RGB#GdkRgbDither>)) value, selecting the desired dither mode.
* buf: The 24-bit pixel data.
* rowstride: The number of bytes from the start of one row in buf to the start of the next.
* xdith: x offset for dither alignment.
* ydith: y offset for dither alignment.
* Returns: self
--- Gdk::RGB.draw_gray_image(win, gc, x, y, w, h, dither, buf, rowstride)
Draws a grayscale image in the Gdk::Drawable.
* win: The Gdk::Drawable to draw in (usually a Gdk::Window).
- * gc: The Gdk::GC graphics context to control the drawing style.
+ * gc: The ((<Gdk::GC>)) graphics context to control the drawing style.
* x: The x coordinate of the top-left corner of the rectangle in the drawable.
* y: The y coordinate of the top-left corner of the rectangle in the drawable.
* w: The width of the rectangle to be drawn.
* h: The height of the rectangle to be drawn.
- * dither: A GdkRgbDither value, selecting the desired dither mode.
+ * dither: A ((<GdkRgbDither|Gdk::RGB#GdkRgbDither>)) value, selecting the desired dither mode.
* buf: The pixel data, represented as 8-bit gray values.
* rowstride: The number of bytes from the start of one row in buf to the start of the next.
* Returns: self
--- Gdk::RGB.draw_rgb_32_image(win, gc, x, y, w, h, dither, buf, rowstride)
Draws a padded RGB image in the Gdk::Drawable. The image is stored as one pixel per 32-bit word. It is laid out as a red byte, a green byte, a blue byte, and a padding byte.
* win: The Gdk::Drawable to draw in (usually a Gdk::Window).
- * gc: The Gdk::GC graphics context to control the drawing style.
+ * gc: The ((<Gdk::GC>)) graphics context to control the drawing style.
* x: The x coordinate of the top-left corner of the rectangle in the drawable.
* y: The y coordinate of the top-left corner of the rectangle in the drawable.
* w: The width of the rectangle to be drawn.
* h: The height of the rectangle to be drawn.
- * dither: A GdkRgbDither value, selecting the desired dither mode.
+ * dither: A ((<GdkRgbDither|Gdk::RGB#GdkRgbDither>)) value, selecting the desired dither mode.
* buf: The 32-bit pixel data.
* rowstride: The number of bytes from the start of one row in buf to the start of the next.
* Returns: self
