ccDisplayConsole

创建

貌似ccDisplayConsole对象一创建就会打开一个窗口，该窗口非MFC主框架窗口，而是一个单独的对话框。

console.image(imageRGB32Pel);

eOverlayPlane 显示多图层

console.enableOverlay(ccWin32Display::eOverlayPlane);

removeImage()

console.removeImage();

getDisplayedImage()

获取当前显示的图像。

mag & magExact & fit & fitExact

设置或获取显示放大倍数，正数为放大，负数为缩小。

void mag(c_Int32 m);
c_Int32 mag() const;
display->mag(-2); // one-half actual size
display->magExact(1.52); //1.52x actual size
display->magExact(0.52); //0.52x actual size

CloseAction

设置窗口关闭按钮的功能，禁用，关闭窗口，隐藏窗口

enum CloseAction { eCloseDisabled, eCloseHide, eCloseDelete };
void closeAction (CloseAction action);
CloseAction closeAction() const { return closeAction_; }

ccUITablet tablet;
ccPoint where(20, 20);
tablet.drawPointIcon(where, ccColor::red);
tablet.draw(cmT("Point (2,2)"), where, ccColor::blue,        ccColor::yellow, ccUIFormat());
console.drawSketch(tablet.sketch(), ccDisplay::eDisplayCoords);

PostMessage

cfInitializeDisplayResources 初始化

When your application calls a CVL display API in your DLL, Windows looks in your DLL for the necessary resources, but does not find them there. Calling cfInitializeDisplayResources() in your application informs Windows that the CVL display resources are to be found in cogdisp.dll, and not in your DLL.

interpolation

图像显示插值处理

display->interpolation(ccUITablet::eBilinear);

displayFormat

获取桌面颜色位数

ccDisplay::DisplayFormat d= console.displayFormat();
