的drawText [英] Drawtext
问题描述
我正在使用以下代码在SDI应用程序中绘制文本。
CFont字体;
font.CreateFont(20,100,0,0,0,0,0,0,0,0,0,0,_T("Arial"));
CFont * pOldFont = pDC-> SelectObject(& font);
pDC-> FillSolidRect(rect,RGB(128,128,128)); //深灰色
pDC-> SetBkMode(TRANSPARENT);
pDC-> SetTextColor(RGB(0,255,255));
pDC-> DrawText(L" Hello",6& rect,DT_CENTER);
当背景为白色时,文字颜色不同,而背景为darkgraycolor文本颜色看起来略有不同虽然我使用相同的文本颜色。如何使用
darkgraycolor作为背景,获得与白色背景相同的文本颜色。
谢谢。
这是一种视觉错觉。颜色是一样的,但背景颜色让你觉得它不是。遗憾。
Hi,
I am drawing text in SDI application using below code.
CFont font;
font.CreateFont(20,100, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, _T("Arial"));
CFont* pOldFont = pDC->SelectObject(&font);
pDC->FillSolidRect(rect,RGB(128,128,128)); //dark gray
pDC->SetBkMode(TRANSPARENT);
pDC->SetTextColor(RGB(0,255,255));
pDC->DrawText(L"Hello",6, &rect, DT_CENTER);
When background is white color the text color is different whereas when the background is in darkgraycolor the text color looks slightly different eventhough I am using same text color.How to achieve same text color as getting on white background, when using
darkgraycolor as background also.
Thanks.
This is a visual illusion. The colour is the same, but the background colour makes you think that it's not. Sorry.
