A Bitmap is a rectangular array of pixels.
It supports two representations of these pixels: a client-side pixel buffer, and a server-side pixmap which is stored in an organization directly compatible with the screen, for fast drawing onto the device. The server-side representation is not directly accessible from the current process as it lives in the process of the X Server or GDI. The client-side pixel array is of size height x (width+7)/8 bytes, in other words 8 pixels packed into a single byte, starting at bit 0 on the left.

Create a bitmap.
If a client-side pixel buffer has been specified, the bitmap does not own the pixel buffer unless the BITMAP_OWNED flag is set. If the BITMAP_OWNED flag is set but a NULL pixel buffer is passed, a pixel buffer will be automatically created and will be owned by the bitmap. The flags BITMAP_SHMI and BITMAP_SHMP may be specified for large bitmaps to instruct render() to use shared memory to communicate with the server.

Cleanup.
void FX::FXBitmap::setOptions | ( | FXuint | opts | ) |
Change options.
|
inline |
To get to the option flags.
Populate the bitmap with new pixel data of the same size; it will assume ownership of the pixel data if image BITMAP_OWNED option is passed.
The server-side representation of the image, if it exists, is not updated. This can be done by calling render().
Populate the bitmap with new pixel data of a new size; it will assume ownership of the pixel data if image BITMAP_OWNED option is passed.
The size of the server- side representation of the image, if it exists, is adjusted but the contents are not updated yet. This can be done by calling render().

inline |
To get to the pixel data.
|
virtual |
Create the server side pixmap, then call render() to fill it with the pixel data from the client-side buffer.
After the server-side image has been created, the client-side pixel buffer will be deleted unless BITMAP_KEEP has been specified. If the pixel buffer is not owned, i.e. the flag BITMAP_OWNED is not set, the pixel buffer will not be deleted.
Reimplemented from FX::FXId.
|
virtual |
Detach the server side pixmap from the Bitmap.
Afterwards, the Bitmap is left as if it never had a server-side resources.
Reimplemented from FX::FXId.
|
virtual |
Destroy the server-side pixmap.
The client-side pixel buffer is not affected.
Reimplemented from FX::FXId.
|
virtual |
Retrieves pixels from the server-side bitmap.
|
virtual |
Render the server-side representation of the bitmap from client-side pixels.
|
virtual |
Release the client-side pixels buffer, free it if it was owned.
If it is not owned, the image just forgets about the buffer.
Resize both client-side and server-side representations (if any) to the given width and height.
The new representations typically contain garbage after this operation and need to be re-filled.
Reimplemented from FX::FXDrawable.
Rescale pixels image to the specified width and height; this calls resize() to adjust the client and server side representations.
Mirror bitmap horizontally and/or vertically.
|
virtual |
Rotate bitmap by degrees ccw.
Crop bitmap to given rectangle; this calls resize() to adjust the client and server side representations.
The new bitmap may be smaller or larger than the old one; blank areas are filled with color. There must be at least one pixel of overlap between the old and the new bitmap.
|
virtual |
Fill bitmap with uniform value.

Save object to stream.
Reimplemented from FX::FXDrawable.

Load object from stream.

Save pixel data only.
|
