]Bitmap class
Represents a GDI+ bitmap image. Objects of this class should only be allocated using System::MakeObject() function. Never create instance of this type on stack or using operator new, as it will result in runtime errors and/or assertion faults. Always wrap this class into System::SmartPtr pointer and use this pointer to pass it to functions as argument.
class Bitmap : public System::Drawing::Image
Methods
| Method | Description |
|---|---|
| BeginPixelProcessing(bool) | Enables pixel processing mode. |
| Bitmap(const SharedPtr<Image>&) | Constructs a new Bitmap object from the specified existing image. |
| Bitmap(const SharedPtr<System::IO::Stream>&, bool) | Constructs a new Bitmap object from the specified stream. |
| Bitmap(const String&) | Constructs a new Bitmap object from the specified file. |
| Bitmap(const String&, bool) | Constructs a new Bitmap object from the specified file. |
| Bitmap(int, int, Imaging::PixelFormat) | Constructs a new Bitmap object that represents a bitmap image with the specified width, height, pixel format and pixel data. |
| Bitmap(const SharedPtr<Image>&, const Size&) | Constructs a new Bitmap object from the specified existing image, scaled to the specified size. |
| Bitmap(const SharedPtr<Image>&, int, int) | Constructs a new Bitmap object from the specified existing image with width and height scaled to the specified values. |
| Clone() override | Creates a copy of the current object. |
| Clone(Rectangle, Imaging::PixelFormat) | Creates a Bitmap object that represents a copy of a region of the bitmap image represented by the current object. |
| Clone(RectangleF, Imaging::PixelFormat) | Creates a Bitmap object that represents a copy of a region of the bitmap image represented by the current object. |
| ComputeHash() | Computes the SHA1 hash value. |
| static ConvertToARGBImage(const SharedPtr<Bitmap>&) | Creates a copy of the specified bitmap image with pixel format changed to Format32bppArgb. |
| EndPixelProcessing(bool) | Disables pixel processing mode. |
| get_Height() const override | Returns the height of the image in pixels. |
| get_Palette() const override | Returns the color palette used by the image represented by the current object. |
| get_PixelFormat() const override | Returns the pixel format of the image represented by the current object. |
| get_RawFormat() const override | Returns the file format of the image represented by the current object. |
| get_Width() const override | Returns the width of the image in pixels. |
| GetHbitmap() | Creates a GDI bitmap object from the bitmap represented by the current object. |
| GetPixel(int, int) | Returns the color of the specified pixel. |
| GetSkBitmap() const override | Returns a raw pointer to the underlying SkBitmap object. |
| IsMultiImage() const override | Returns whether the original format is a multi-image. |
| LockBits(const Rectangle&, Imaging::ImageLockMode, Imaging::PixelFormat) | Locks a Bitmap into system memory. |
| LockBits(const Rectangle&, Imaging::ImageLockMode, Imaging::PixelFormat, const Imaging::BitmapDataPtr&) | Locks a Bitmap into system memory. |
| MakeTransparent(Color) | Changes the color of all pixels with the specified color to transparent. |
| MEMBER_FUNCTION_MAKE_OBJECT(Bitmap, CODEPORTING_ARGS(const SharedPtr<Image>&original, int width, int height), CODEPORTING_ARGS(original, width, height)) | |
| PremultipleColors() | Premultiplies the colors of the pixels of the image represented by the current object. |
| RotateFlip(RotateFlipType) override | Rotates image to multiple of 90 degrees and flips. |
| set_Palette(Imaging::ColorPalettePtr) override | Sets the color palette used by the image represented by the current object. |
| SetPixel(int, int, Color) | Sets the color of the specified pixel in the bitmap image represented by the current object. |
| SetResolution(float, float) | Sets the resolution of the image. |
| UnlockBits(const Imaging::BitmapDataPtr&) | Unlocks the specified bitmap from system memory. |
