|
Empty constructor. Constructors in derived classes create a small empty bitmap to ensure that the object is always in a sane state. |
|
|
Test for equality. This function actually tests every pixel, so it's not fast. It's meant mainly for use in asserts and such. |
|
||||||||||||||||||||||||
|
Creates a new empty bitmap. Memory for the bits is allocated but not initialized. Previous contents of the bitmap object are discarded |
|
||||||||||||
|
Creates from a bitmap header.
|
|
||||||||||||
|
Creates a copy of rSrImage, applying rFilter on the way. Depending on the filter called, this is often much faster than CreateCopy() followed by ApplyFilter(). |
|
|
Change orientation of the image to new one.
|
|
|
Change image format.
|
|
|
Change image pixel representetion.
|
|
||||||||||||
|
Locks bitmap. GetLineArray() and other direct-access methods should only be called if the bitmap is locked. Lock and Unlock keep a lock count. |
|
||||||||||||||||||||||||
|
Create a new bitmap with uninitialized bits. (Assume no memory is allocated yet.) Implemented in GDIImage, IntelImage, and SimpleImage. |
|
|
Creates a new Image as copy of rSrImage. Assumes there is no memory allocated yet. |
|
|
Change image orientation to given state
Implemented in GDIImage, IntelImage, and SimpleImage. |
|
|
Number of times the bitmap was locked. Default is m_LockCount always >= 1, so access to bits is always possible. |
