TdxFastDIB Class
A memory DC-based buffer for DIB images.
Declaration
TdxFastDIB = class(
TdxCustomFastDIB
)Remarks
This memory buffer is a lightweight container for 32-bit DIB (device-independent bitmap) images, designed to work with GDI draw routines and bitmap draw methods implemented in DevExpress canvas classes. The buffer associates a memory device context with image dimensions and a pixel data array.
The TdxFastDIB class has the following members that allow you to:
Create an image buffer (Create).
Access a memory device context that contains the image to perform draw operations (DC).
Identify if the buffer has zero size (Empty).
Obtain the image buffer’s dimensions and client rect (Width, Height, and ClientRect).
Access the stored image’s array of pixels (Bits).
Clear the image buffer (Clear).
Recreate the image buffer with the specified dimensions (Resize).
The TcxCustomCanvas.DrawBitmap procedure accepts a TdxFastDIB class instance as a bitmap source.
