Creates a copy of the section of this xtd::drawing::bitmap defined with a specified rectangle.

Parameters
rectDefines the portion of this bitmap to copy.

◆ clone() [2/2]

bitmap xtd::drawing::bitmap::clone ( const rectangle_f rect) const

Creates a copy of the section of this xtd::drawing::bitmap defined with a specified rectangle.

Parameters
rectDefines the portion of this bitmap to copy.

◆ get_hbitmap() [1/2]

intptr xtd::drawing::bitmap::get_hbitmap ( ) const

Creates a GDI bitmap object from this xtd::drawing::bitmap.

Returns
A handle to the GDI bitmap object that this method creates.
Remarks
You are responsible for calling the GDI DeleteObject method to free the memory used by the GDI bitmap object. For more information about GDI bitmaps, see Bitmaps in the Windows GDI documentation.

◆ get_hbitmap() [2/2]

intptr xtd::drawing::bitmap::get_hbitmap ( const color background) const

Creates a GDI bitmap object from this xtd::drawing::bitmap.

Parameters
backgroundA xtd::drawing::color structure that specifies the background color. This parameter is ignored if the bitmap is totally opaque.
Returns
A handle to the GDI bitmap object that this method creates.
Remarks
You are responsible for calling the GDI DeleteObject method to free the memory used by the GDI bitmap object. For more information about GDI bitmaps, see Bitmaps in the Windows GDI documentation.

◆ get_hicon()

intptr xtd::drawing::bitmap::get_hicon ( ) const

Returns the handle to an icon.

Returns
A Windows handle to an icon with the same image as the xtd::drawing::bitmap.
Remarks
Initially, an icon created from the handle will have the same size as the original bitmap.

◆ get_pixel()

drawing::color xtd::drawing::bitmap::get_pixel ( int32  x,
int32  y 
) const

Gets the color of the specified pixel in this bitmap.

Parameters
xThe x-coordinate of the pixel to retrieve.
yThe y-coordinate of the pixel to retrieve.
Returns
A xtd::drawing::color structure that represents the color of the specified pixel.

◆ lock_bits() [1/2]

Locks a xtd::drawing::bitmap into system memory.

Parameters
rectA xtd::drawing::rectangle structure that specifies the portion of the xtd::drawing::bitmap to lock.
flagsAn xtd::drawing::imaging::image_lock_mode enumeration that specifies the access level (read/write) for the xtd::drawing::bitmap.
formatA xtd::drawing::imaging::pixel_format enumeration that specifies the data format of this xtd::drawing::bitmap.
Returns
A xtd::drawing::imaging::bitmap_data that contains information about this lock operation.
Remarks
Use the xtd::drawing::bitmap::lock_bits method to lock an existing bitmap in system memory so that it can be changed programmatically. You can change the color of an image with the xtd::drawing::bitmap::set_pixel method, although the xtd::drawing::bitmap::lock_bits method offers better performance for large-scale changes.
The xtd::drawing::imaging::bitmap_data specifies the attributes of the xtd::drawing::bitmap, such as size, pixel format, the starting address of the pixel data in memory, and length of each scan line (stride).
When calling this method, you should use a member of the xtd::drawing::imaging::pixel_format enumeration that contains a specific bits-per-pixel (BPP) value. Using xtd::drawing::imaging::pixel_format values such as xtd::drawing::imaging::pixel_format::indexed and xtd::drawing::imaging::pixel_format::gdi will throw an xtd::argument_exception. Also, passing the incorrect pixel format for a bitmap will throw an xtd::argument_exception.

◆ lock_bits() [2/2]

Locks a xtd::drawing::bitmap into system memory.

Parameters
rectA xtd::drawing::rectangle structure that specifies the portion of the xtd::drawing::bitmap to lock.
flagsAn xtd::drawing::imaging::image_lock_mode enumeration that specifies the access level (read/write) for the xtd::drawing::bitmap.
formatA xtd::drawing::imaging::pixel_format enumeration that specifies the data format of this xtd::drawing::bitmap.
dataA xtd::drawing::imaging::bitmap_data that contains information about the lock operation.
Returns
A xtd::drawing::imaging::bitmap_data that contains information about this lock operation.
Remarks
Use the xtd::drawing::bitmap::lock_bits method to lock an existing bitmap in system memory so that it can be changed programmatically. You can change the color of an image with the xtd::drawing::bitmap::set_pixel method, although the xtd::drawing::bitmap::lock_bits method offers better performance for large-scale changes.
The xtd::drawing::imaging::bitmap_data specifies the attributes of the xtd::drawing::bitmap, such as size, pixel format, the starting address of the pixel data in memory, and length of each scan line (stride).
When calling this method, you should use a member of the xtd::drawing::imaging::pixel_format enumeration that contains a specific bits-per-pixel (BPP) value. Using xtd::drawing::imaging::pixel_format values such as xtd::drawing::imaging::pixel_format::indexed and xtd::drawing::imaging::pixel_format::gdi will throw an xtd::argument_exception. Also, passing the incorrect pixel format for a bitmap will throw an xtd::argument_exception.

◆ make_transparent() [1/2]

void xtd::drawing::bitmap::make_transparent ( )

Makes the default transparent color transparent for this xtd::drawing::bitmap.

Remarks
The system palette defines one color as the default transparent, or alpha, color. This method makes the default transparent color transparent for this xtd::drawing::bitmap. If no transparent color is specified by the system, xtd::drawing::color::light_gray is the transparent color.
When you call xtd::drawing::bitmap::make_transparent, the bitmap will be converted to the xtd::drawing::imaging::pixel_format::format_32bpp_argb format, as this format supports an alpha channel.

◆ make_transparent() [2/2]

void xtd::drawing::bitmap::make_transparent ( const color transparent_color)

Makes the specified color transparent for this xtd::drawing::bitmap.

Parameters
transprent_colorThe xtd::drawing::color structure that represents the color to make transparent.
Remarks
When you call xtd::drawing::bitmap::make_transparent, the bitmap will be converted to the xtd::drawing::imaging::pixel_format::format_32bpp_argb format, as this format supports an alpha channel.

◆ set_pixel()

void xtd::drawing::bitmap::set_pixel ( int32  x,
int32  y,
const drawing::color color 
)

Sets the color of the specified pixel in this xtd::drawing::bitmap.

Parameters
xThe x-coordinate of the pixel to retrieve.
yThe y-coordinate of the pixel to retrieve.
colorA xtd::drawing::color structure that represents the color of the specified pixel.

◆ set_resolution()

)

Sets the resolution for this xtd::drawing::bitmap.

Parameters
x_dpiThe horizontal resolution, in dots per inch, of the xtd::drawing::bitmap.
y_dpiThe vertical resolution, in dots per inch, of the xtd::drawing::bitmap.
