S206: obtaining the input video source texture for the video content that the LED strip screen after giving a discount of the display plays,
And the input video source texture of the acquisition is cut according to the discounting mode.
It can be found that in the present embodiment, video that the LED strip screen after giving a discount of the available display plays
The input video source texture of content, and the input video source texture of the acquisition is cut according to the discounting mode, it is such
Benefit is the storage for facilitating the segment for the video content that LED strip screen is played to carry out any position.
It is exemplified below the present embodiment:
One, assume that resolution ratio is the high LED strip screen of width of 8132*128, normal individual calculus generator terminal now with one piece
Synchronous resolution ratio is 1920*1080, in order to which normal editing program and digital visual interface export, so needing to the LED long
The video-frequency playing content of item screen carries out discounting processing；
Two, discounting window is created, sets the coordinate position of window first, and sets width as 1920, is highly 8132*
128/1980, window discounting mode is finally set, in this strip screen is given a discount according to width；
Three, it gives a discount according to width, calculates the rectangular area for needing to render, source texture region m_rtSrc is stated, after discounting
Region m_rtDes is rendered, then can render region by the following target that generates:
CRect rtDesTemp, rtSrcTemp；
Int nType=0；
Int number=0；
Int nSrcW=0；// original width, 8132
Int nDesW=0；// window width, 1920
vector<CRect>m_rtSrc；// source texture region vector
vector<CRect>m_rtDes；// rendering region vector
Number=nSrcW/nDesW；// obtain discounting number of segment
if(number>0)
{
for(；k<number；k++)
{
RtSrcTemp.left=nSrcTemp；
RtSrcTemp.right=rtSrcTemp.left+nDesW；
RtSrcTemp.top=rtSrc.top；
RtSrcTemp.bottom=rtSrc.bottom；
NSrcTemp=rtSrcTemp.right；The right coordinate of the upper cut point of // preservation
RtDesTemp.left=rtDes.left；
RtDesTemp.right=rtDes.right；
RtDesTemp.top=nDesTemp；
RtDesTemp.bottom=rtDesTemp.top+nSrcH；
NDesTemp=rtDesTemp.bottom；The bottom coordinate of the upper cut point of // preservation
m_rtSrc.push_back(&rtSrcTemp)；// coordinate of well cutting source texture region is saved in source texture
In the vector of region
m_rtDes.push_back(&rtDesTemp)；// well cutting rendering region coordinate be saved in rendering region
In vector
}
}
Four, it after getting source texture region and the coordinate in rendering region, is rendered with D3D+GDI technology, method is such as
Under:
StretchBlt (HDC hDesDC, CRect rtDes, HDC hSrcDC, CRect rtSrc, SRCCOPY)；
Five；After being created that new texture, texture display to screen, carries out rendering and show, can be realized and pass through handle
