Maciej Suminski ad4a72ff11 Cairo now renders layers properly (colors are not saturated after layer composition), but slower. 2013-04-19 18:19:50 +02:00
Maciej Suminski 062fc2d200 Some cleanup. 2013-04-19 18:19:20 +02:00
Maciej Suminski e4bac0d91a Fixed resize issue (moved GAL panel into pane).
Tidied up event handlers.

Maciej Suminski 16a28348b4 Added const(..)& in GAL methods' parameters and change iterators to constant iterators. 2013-04-17 12:48:37 +02:00
Maciej Suminski 520be6f67b Added GAL::DrawSegment for drawing rounded segments (used for drawing tracks). 2013-04-17 12:38:00 +02:00
Maciej Suminski bee0d69289 Cleanup 2013-04-16 11:16:27 +02:00
Maciej Suminski 5b9057823a Introduced SetGAL() functions that will allow changing GAL backend for rendering on the fly. 2013-04-15 16:03:05 +02:00
Maciej Suminski 877dd3f79a Added multiline strings and text overbars rendering using GAL. 2013-04-11 14:21:59 +02:00
Maciej Suminski ccd2ebefd3 Removed OpenGL different drawing modes, as they were not used.
Removed DRAW_MODE_NORMAL, DRAW_MODE_PREPARE_EDGES, DRAW_MODE_DRAW_EDGES modes.

Maciej Suminski 826d5a8954 Added GetMinDepth()/GetMaxDepth() methods (useful for displaying things on the top or on the bottom). 2013-04-04 11:21:35 +02:00
Maciej Suminski e262b32198 Introduction of Graphics Abstraction Layer based rendering for pcbnew.
New classes:
    - VIEW - represents view that is seen by user, takes care of layer ordering & visibility and how it is displayed (which location, how much zoomed, etc.)
    - VIEW_ITEM - Base class for every item that can be displayed on VIEW (the biggest change is that now it may be necessary to override ViewBBox & ViewGetLayers method for derived classes).
    - EDA_DRAW_PANEL_GAL - Inherits after EDA_DRAW_PANEL, displays VIEW output, right now it is not editable (in opposite to usual EDA_DRAW_PANEL).
    - GAL/OPENGL_GAL/CAIRO_GAL - Base Graphics Abstraction Layer class + two different flavours (Cairo is not fully supported yet), that offers methods to draw primitives using different libraries.
    - WX_VIEW_CONTROLS - Controller for VIEW, handles user events, allows zooming, panning, etc.
    - PAINTER/PCB_PAINTER - Classes that uses GAL interface to draw items (as you may have already guessed - PCB_PAINTER is a class for drawing PCB specific object, PAINTER is an abstract class). Its methods are invoked by VIEW, when an item has to be drawn. To display a new type of item - you need to implement draw(ITEM_TYPE*) method that draws it using GAL methods.
    - STROKE_FONT - Implements stroke font drawing using GAL methods.
                          
Most important changes to Kicad original code:
    * EDA_ITEM now inherits from VIEW_ITEM, which is a base class for all drawable objects.
    * EDA_DRAW_FRAME contains both usual EDA_DRAW_PANEL and new EDA_DRAW_PANEL_GAL, that can be switched anytime.
    * There are some new layers for displaying multilayer pads, vias & pads holes (these are not shown yet on the right sidebar in pcbnew)
    * Display order of layers is different than in previous versions (if you are curious - you may check m_galLayerOrder@pcbnew/basepcbframe.cpp). Preserving usual order would result in not very natural display, such as showing silkscreen texts on the bottom.
    * Introduced new hotkey (Alt+F12) and new menu option (View->Switch canvas) for switching canvas during runtime.
    * Some of classes (mostly derived from BOARD_ITEM) now includes ViewBBox & ViewGetLayers methods.
    * Removed tools/class_painter.h, as now it is extended and included in source code.
                         
Build changes:
    * GAL-based rendering option is turned on by a new compilation CMake option KICAD_GAL.
    * When compiling with CMake option KICAD_GAL=ON, GLEW and Cairo libraries are required.
    * GAL-related code is compiled into a static library (common/libgal).
    * Build with KICAD_GAL=OFF should not need any new libraries and should come out as a standard version of Kicad
                            
Currently most of items in pcbnew can be displayed using OpenGL (to be done are DIMENSIONS and MARKERS).

Maciej Suminski ad4bf38e7a Added class COLOR4D that contains color representation with 4 components (RGBA) (for future usage in GAL) 2013-03-28 17:42:15 +01:00
