pixel_format

enum class xtd::drawing::imaging::pixel_format

strong

Specifies the format of the color data for each pixel in the image.

Namespace

xtd::drawing::imaging

Library

xtd.drawing

Remarks

The pixel format defines the number of bits of memory associated with one pixel of data. The format also defines the order of the color components within a single pixel of data.

PixelFormat48bppRGB, PixelFormat64bppARGB, and PixelFormat64bppPARGB use 16 bits per color component (channel). GDI+ version 1.0 and 1.1 can read 16-bits-per-channel images, but such images are converted to an 8-bits-per-channel format for processing, displaying, and saving. Each 16-bit color channel can hold a value in the range 0 through 2^13.

Some of the pixel formats contain premultiplied color values. Premultiplied means that the color values have already been multiplied by an alpha value.

Enumerator
undefined	The pixel format is undefined.
dont_care	No pixel format is specified.
max	The maximum value for this enumeration.
indexed	The pixel data contains color-indexed values, which means the values are an index to colors in the system color table, as opposed to individual color values.
gdi	The pixel data contains GDI colors.
format_16bpp_rgb555	Specifies that the format is 16 bits per pixel; 5 bits each are used for the red, green, and blue components. The remaining bit is not used.
format_16bpp_rgb565	Specifies that the format is 16 bits per pixel; 5 bits are used for the red component, 6 bits are used for the green component, and 5 bits are used for the blue component.
format_24bpp_rgb	Specifies that the format is 24 bits per pixel; 8 bits each are used for the red, green, and blue components.
format_32bpp_rgb	Specifies that the format is 32 bits per pixel; 8 bits each are used for the red, green, and blue components. The remaining 8 bits are not used.
format_1bpp_indexed	Specifies that the pixel format is 1 bit per pixel and that it uses indexed color. The color table therefore has two colors in it.
format_4bpp_indexed	Specifies that the format is 4 bits per pixel, indexed.
format_8bpp_indexed	Specifies that the format is 8 bits per pixel, indexed. The color table therefore has 256 colors in it.
alpha	The pixel data contains alpha values that are not premultiplied.
format_16bpp_argb1555	The pixel format is 16 bits per pixel. The color information specifies 32,768 shades of color, of which 5 bits are red, 5 bits are green, 5 bits are blue, and 1 bit is alpha.
palpha	The pixel format contains premultiplied alpha values.
format_32bpp_pargb	Specifies that the format is 32 bits per pixel; 8 bits each are used for the alpha, red, green, and blue components. The red, green, and blue components are premultiplied, according to the alpha component.
extended	Reserved.
format_16bpp_gray_scale	The pixel format is 16 bits per pixel. The color information specifies 65536 shades of gray.
format_48bpp_rgb	Specifies that the format is 48 bits per pixel; 16 bits each are used for the red, green, and blue components.
format_64bpp_pargb	Specifies that the format is 64 bits per pixel; 16 bits each are used for the alpha, red, green, and blue components. The red, green, and blue components are premultiplied according to the alpha component.
canonical	The default pixel format of 32 bits per pixel. The format specifies 24-bit color depth and an 8-bit alpha channel.
format_32bpp_argb	Specifies that the format is 32 bits per pixel; 8 bits each are used for the alpha, red, green, and blue components.
format_64bpp_argb	Specifies that the format is 64 bits per pixel; 16 bits each are used for the alpha, red, green, and blue components.
