ANIMATEINFO
2.0
Animation information used by the DrawPenDataEx function for animation control.
typedef struct {
DWORD cbSize;
UINT uSpeedPct;
UINT uPeriodCB;
UINT fuFlags;
LPARAM lParam;
DWORD dwReserved;
} ANIMATEINFO;
Members
cbSize
Size of this structure in bytes.
uSpeedPct
Drawing speed, expressed as a percentage of the user's entry speed. To redraw
pen data at the same speed at which it was created, this value should be set to
100. A value of 0 halts drawing. Setting uSpeedPct to 0 is valid only if the lpfnAnimateCB parameter of DrawPenDataEx is defined. Otherwise, the drawing halts with no way to restart it. uSpeedPct can be changed by a call-back function.
uPeriodCB
Callback period in milliseconds. Typical values are 1 (very fast), 250 (fast),
1000 (slow), or 0 (never). Any value in uPeriodCB is ignored if the DrawPenDataEx argument lpfnAnimateCB is NULL. uPeriodCB may also be AI_CBSTROKE, to indicate that the callback should occur after
each stroke is drawn.
fuFlags
Flags that control animation (can be 0). The AI_SKIPUPSTROKES option specifies
that the time taken to account for the points in the up strokes should be
ignored. If this flag is 0, and if the value in uSpeedPct is small enough, there will be a delay between pen-down strokes, reflecting
the user's inter-stroke delay during creation of the pen data.
lParam
Application value to pass to the callback function set up by the lpfnAnimateCB argument of DrawPenDataEx.
dwReserved
Must be 0.
Comments
Before using ANIMATEINFO, an application must initialize cbSize with sizeof( ANIMATEINFO ).

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
