CImage Members

Operators

operator HBITMAP

Returns the Windows handle attached to the CImage object.

Construction

CImage

The constructor.

Operations

AlphaBlend	Displays bitmaps that have transparent or semitransparent pixels.
Attach	Attaches an HBITMAP to a CImage object. Can be used with either non-DIB section bitmaps or DIB section bitmaps.
BitBlt	Copies a bitmap from the source device context to this current device context.
Create	Creates a DIB section bitmap and attaches it to the previously constructed CImage object.
CreateEx	Creates a DIB section bitmap (with additional parameters) and attaches it to the previously constructed CImage object.
Destroy	Detaches the bitmap from the CImage object and destroys the bitmap.
Detach	Detaches the bitmap from a CImage object.
Draw	Copies a bitmap from a source rectangle into a destination rectangle. Draw stretches or compresses the bitmap to fit the dimensions of the destination rectangle, if necessary, and handles alpha blending and transparent colors.
GetBits	Retrieves a pointer to the actual pixel values of the bitmap.
GetBPP	Retrieves the bits per pixel.
GetColorTable	Retrieves red, green, blue (RGB) color values from a range of entries in the color table.
GetDC	Retrieves the device context into which the current bitmap is selected.
GetExporterFilterString	Finds the available image formats and their descriptions.
GetImporterFilterString	Finds the available image formats and their descriptions.
GetHeight	Retrieves the height of the current image in pixels.
GetMaxColorTableEntries	Retrieves the maximum number of entries in the color table.
GetPitch	Retrieves the pitch of the current image, in bytes.
GetPixelAddress	Retrieves the address of a given pixel.
GetPixel	Retrieves the color of the pixel specified by x and y.
GetTransparentColor	Retrieves the position of the transparent color in the color table.
GetWidth	Retrieves the width of the current image in pixels.
IsDibSection	Determines if the attached bitmap is a DIB section.
IsIndexed	Indicates that a bitmap's colors are mapped to an indexed palette.
IsNull	Indicates if a source bitmap is currently loaded.
IsTransparencySupported	Indicates whether the application supports transparent bitmaps and was compiled for Windows 2000 or later.
LoadFromResource	Loads an image from the specified resource.
Load	Loads an image from the specified file.
MaskBlt	Combines the color data for the source and destination bitmaps using the specified mask and raster operation.
PlgBlt	Performs a bit-block transfer from a rectangle in a source device context into a parallelogram in a destination device context.
ReleaseDC	Releases the device context that was retrieved with CImage::GetDC.
ReleaseGDIPlus	Releases resources used by GDI+. Must be called to free resources created by a global CImage object.
Save	Saves an image as the specified type. Save cannot specify image options.
SetColorTable	Sets red, green, blue RGB) color values in a range of entries in the color table of the DIB section.
SetPixelIndexed	Sets the pixel at the specified coordinates to the color at the specified index of the palette.
SetPixelRGB	Sets the pixel at the specified coordinates to the specified red, green, blue (RGB) value.
SetPixel	Sets the pixel at the specified coordinates to the specified color.
SetTransparentColor	Sets the index of the color to be treated as transparent. Only one color in a palette can be transparent.
StretchBlt	Copies a bitmap from a source rectangle into a destination rectangle, stretching or compressing the bitmap to fit the dimensions of the destination rectangle, if necessary.
TransparentBlt	Copies a bitmap with transparent color from the source device context to this current device context.
