| 3 | 3 | *TBGRABitmap* class contains an image stored in BGRA 32-bit format. It derives from *TBGRADefaultBitmap* which derives from [[TBGRACustomBitmap and IBGRAScanner|TBGRACustomBitmap]] from which it inherits its properties. It is defined in [BGRABitmap unit](https://bgrabitmap.github.io/doc/BGRABitmap.html). It implements [[TBGRACustomBitmap and IBGRAScanner|IBGRAScanner]] interface which allows it to be used as a texture (like a brush). | |

| 5 | 5 | ### Implementations | |
| 6 | 6 | ||
| 7 | 7 | *TBGRABitmap* is a shortcut provided by [BGRABitmap unit](https://bgrabitmap.github.io/doc/BGRABitmap.html) for the active implementation, depending on the widgetset. It can be one of the following: | |
| 8 | 8 | ||
| 9 | 9 | - *TBGRAWinBitmap* or *TBGRAMSEguiBitmap* on Windows | |
| 10 | 10 | - *TBGRAGtkBitmap* on Gtk | |
| 11 | 11 | - *TBGRAQtBitmap* when Qt widget is active | |
| 12 | 12 | - *TBGRAfpGUIBitmap* when using the package for fpGUI toolkit (*bgrabitmappack4fpgui.lpk*) | |
| 13 | 13 | - *TBGRANoGUIBitmap* when using the package independent of the graphic user interface (*bgrabitmappack4nogui.lpk*) | |
| 14 | 14 | - *TBGRADefaultBitmap* otherwise | |
| 15 | 15 | ||
| 16 | 16 | ### Direct pixel access | |
| 17 | 17 | ||
| 18 | 18 | The image is stored as BGRA 32-bit: | |

| 88 | 26 | Each pixel is a sequence of 4 bytes containing blue, green, red and alpha channel. Values range from 0 to 255, color is in sRGB colorspace. The alpha value of 0 is transparent and 255 is opaque | |

| 91 | - | ||
| 92 | - | ||

| 94 | - | ||
| 95 | - | ||
| 96 | 28 | You can either use *Data* property if you want to go through all pixels, or *ScanLine* property if you want to do something that depends on the line number. *Data* returns the first pixel in memory, so that you can read all the pixels from there by increasing the pointer (add 1 to *PBGRAPixel*). Otherwise, you can do a loop where *y* goes from 0 to *Height*-1, and for each line, retrieve with *ScanLine* the pointer of the beginning of the line. Then you can read all the pixels of the line from there by increasing the pointer. | |
| 97 | 29 | ||
| 98 | 30 | The following properties of *TBGRABitmap* allow to access the data directly: | |
