# dlangui.graphics.resources

DLANGUI library.
This module contains resource management and drawables implementation.
imageCache is RAM cache of decoded images (as DrawBuf).
drawableCache is cache of Drawables.
Supports nine-patch PNG images in .9.png files (like in Android).
Supports state drawables using XML files similar to ones in Android.

class FrameDrawable: dlangui.graphics.resources.Drawable;
  solid borders (may be of different width) and, optionally, solid inner area
static uint decodeHexColor(string s);
  decode color string #AARRGGBB, e.g. #5599AA
static uint decodeDimension(string s);
  decode size string, e.g. 1px or 2 or 3pt
static Drawable createColorDrawable(string s);
  decode solid color / gradient / frame drawable from string like #AARRGGBB, e.g. #5599AA
  SolidFillDrawable:
  #AARRGGBB - e.g. #8090A0 or #80ffffff
  FrameDrawable:
  #frameColor,frameWidth[,#middleColor] or #frameColor,leftBorderWidth,topBorderWidth,rightBorderWidth,bottomBorderWidth[,#middleColor] e.g. #000000,2,#C0FFFFFF - black frame of width 2 with 75% transparent white middle e.g. #0000FF,2,3,4,5,#FFFFFF - blue frame with left,top,right,bottom borders of width 2,3,4,5 and white inner area
void extractStateFlags(ref string[string] attr, ref uint stateMask, ref uint stateValue);
  converts XML attribute name to State (see http://developer.android.com/guide/topics/resources/drawable-resource.html#StateList)
class StateDrawable: dlangui.graphics.resources.Drawable;
  Drawable which is drawn depending on state (see http://developer.android.com/guide/topics/resources/drawable-resource.html#StateList)
  bool parseList4(T)(string value, ref T[4] items);
    parse 4 comma delimited integers
  bool load(string filename);
    load from XML file
class ImageCache;
  decoded raster images cache (png, jpeg) -- access by filenames
  ref DrawBufRef get(string filename);
    get and cache image
  ref DrawBufRef get(string filename, ref ColorTransform transform);
    get and cache color transformed image
@property ImageCache imageCache();
