我有一阵列,有光镜,我需要在我的申请中显示。 I m programing in C++ with gtkmm and I can t found any widget such as a can You to show and access each pixel in the culture.
根据我的理解,你需要使用以下几类建筑商:
Gdk::Bitmap::Bitmap(const char *data, int width, int height)
a. 制作图和将数据输入地图。
后来,你可以使用Gdk:Pixmap或Gdk: ow。 还有一个Pixbuf类产品储存。
我也试图找到解决办法。 我迄今为止找到的唯一办法(使用格米-3.0)是将光线图像转换为RGB,pixel。
你再分配另一个数据,比原始数据大三倍。 然后,你将每张纸浆从原版复制三倍。 创建1280*1024(我的案子)
Gdk::Pixbuf::create_from_data(copy, Gdk::COLORSPACE_RGB, false, 8, 1280, 1024, 1280*3);
查阅轨道图一中的指数,可使用<>Gdk:Pixbuf:get_pixels()。
