Implementations§
Source§impl Bitmap
impl Bitmap
Sourcepub fn new_for_data(
context: &Context,
width: i32,
height: i32,
format: PixelFormat,
rowstride: i32,
data: &[u8],
) -> Bitmap
pub fn new_for_data( context: &Context, width: i32, height: i32, format: PixelFormat, rowstride: i32, data: &[u8], ) -> Bitmap
Creates a bitmap using some existing data. The data is not copied
so the application must keep the buffer alive for the lifetime of
the Bitmap
. This can be used for example with
Framebuffer::read_pixels_into_bitmap
to read data directly
into an application buffer with the specified rowstride.
§context
A Context
§width
The width of the bitmap.
§height
The height of the bitmap.
§format
The format of the pixel data.
§rowstride
The rowstride of the bitmap (the number of bytes from the start of one row of the bitmap to the next).
§data
A pointer to the data. The bitmap will take ownership of this data.
§Returns
A new Bitmap
.
pub fn from_file(filename: &str) -> Result<Bitmap, Error>
pub fn with_size( context: &Context, width: u32, height: u32, format: PixelFormat, ) -> Bitmap
Sourcepub fn get_buffer(&self) -> Option<PixelBuffer>
pub fn get_buffer(&self) -> Option<PixelBuffer>
§Returns
the PixelBuffer
that this
buffer uses for storage. Note that if the bitmap was created with
Bitmap::new_from_file
then it will not actually be using a
pixel buffer and this function will return None
.
Sourcepub fn get_format(&self) -> PixelFormat
pub fn get_format(&self) -> PixelFormat
§Returns
the PixelFormat
that the data for the bitmap is in.
Sourcepub fn get_height(&self) -> i32
pub fn get_height(&self) -> i32
§Returns
the height of the bitmap
Sourcepub fn get_rowstride(&self) -> i32
pub fn get_rowstride(&self) -> i32
§Returns
the rowstride of the bitmap. This is the number of bytes between the address of start of one row to the address of the next row in the image.
