BGRA Controls is a set of graphical UI elements that you can use with Lazarus LCL applications.
  
−
As many people know, Lazarus GTK doesn't have full alpha support. I created a set of components which use TBGRABitmap for drawing icons, so it partially solves the problem with alpha in GTK.
+
=== TBCButton ===
−
However, this component set is not only a GTK patch but also has more fancy components which use the power of the BGRABitmap package.

Component which inherits from TImageList. So each control (tested on TToolBar and TTreeView) which is using TImageList.Draw method for drawing icons, automatically can have alpha support. Just use this component instead of TImageList. This component has been written for enabling GTK alpha, so on Windows (and other interfaces) it works just like normal TImageList (it doesn't use BGRABitmap for drawing).
+
=== TPSImport_BGRAPascalScript ===
  
−
=== BGRAImageManipulation ===

−
Component to facilitate the importation of images in an application.
+
= BGRA Custom Drawn =
  
−
In the current version you can import an image and cut out keeping the aspect ratio (or not). For example, if you want to import photos using the 3x4 ratio, adjust the 'ratio' property to 3:4. If import an image with different size, the component will ensure that the image meets the proportions of the desired dimensions.
+
BGRA Custom Drawn is a set of controls inherited from Custom Drawn. These come with a default dark style that is like Photoshop.
  
−
You can determine the minimum size of the image adjusting the properties 'MinWidth'and 'MinHeight'.
+
=== TBCDButton ===
  
−
You can rotate the image using functions builtin.
+
A button control that is styled with TBGRADrawer.

−
[[Image:bgraimagemanipulation.jpg]]
+

−
After retrieving the image modified by the component, just put the image into your destination using the stretch. It is obvious that the target must have the same ratio chosen on component for do not distort the final result.

BGRA Controls comes with nice demos to show how to use the stuff and extra things you can use in your own projects.
  
−
With this you can do animations from bitmap. You need an image with all the frames layout in in a horizontal position.
+
=== Pascal Script Library ===
  
−
It has the ability to specify how many times the animation should be played (0 for infinite, 1, 2, etc) and static to stop the animation, is capable to specify the speed and direction and support transparency.
+
Putting BGRABitmap methods into a .dll with c#, java and pascal headers.
  
−
Features:
+
=== BGRA Ribbon Custom ===
−
* Animation: invert, position, lap, speed, static, repeat.
 
−
* Sprite: fill opacity (global transparency), flip mode (horizontal, vertical, both), key color (transparent color), resample (normal or fine resample modes). AutoSize.
 
−
* AnimatedGifToSprite: convert an animated gif to a BGRABitmap sprite.

=== BGRAVirtualScreen ===

How to create a fully themed window using the controls to achieve a Ribbon like application.
−
'''Use as replacement of:''' TPanel, TPaintBox
 
  
−
The principle is to draw on a memory bitmap.
+
=== Tests ===
  
−
The component has a specific event, OnRedraw, which is called when the whole bitmap needs to be redrawn. It happens at the beginning and when the component is resized. You can also query to redraw the bitmap with Redraw and DiscardBitmap methods. The second one only invalidates the content, which can wait until the messageloop is handled.
+
There are test for analog controls (clock and gauge), BC prefixed controls, BGRA prefixed controls, BGRA Custom Drawn controls, how to use Pascal Script and BGRABitmap, bgrascript or how to create your own scripting solution with BGRABitmap.
  
−
Otherwise, it is possible to modify the Bitmap property and call Invalidate or Repaint, to avoid erasing the whole bitmap content.
