QMap - 图像透明融合

图像透明融合是一个将子图像与背景图像进行关系运算，变化子图像外形，改变透明度，最终融合到背景图像的有用工具。

现按软件功能界面介绍如下：

1. 点击鼠标右键选择图像
    打开两幅图像，分别选作子图像和背景图像，再在背景图像上点击鼠标右键选择子图像的显示位置。

2. 颜色最大与最小值的限制
    由于子图像在融合时，我们希望去除一些最亮或暗黑的底色，使融合效果更好，因此，限制最大和最小值可以达到我们的要求。

3. 屏蔽背景色
    一般子图像默认背景色为黑色，当背景色不是黑色时，融合时要去除子图像背景色，可使用屏蔽背景色，点击颜色选择按钮，选择或输入颜色值，便可达到目的。

4. 子图像外形 
    子图像和背景融合时，可选择不同外形，以适合不同要求。具体有矩形，圆角矩形，椭圆，圆等可选。

5. 关系运算
    当两图像融合时，像素间有很多运算方式，如与，或，异或，取反，加减等，可根据实际要求选择。

6. 透明度选择
    透明度选择为0 时不透明，100%时为全透明，默认为50%。

7. 点击处理按钮后弹出新窗口，显示融合后的效果。

QMap - Resize

Image
 Image resizing is the overall scaling of an image to suit different applications. Now according to the software function interface, the introduction is as follows: 1.  Select image      Right-click on the image to select the image. At the same time, the original size (width and height) of the image is rendered in the edit box. 2. Bound ratio      By default, select " Bound ratio ", modify the width of the edit box, the corresponding height will be changed according to the aspect ratio of the original image, and vice versa. The image can also be changed out of proportion, resulting in distortion. 3.  Process     Click the " Process " button to process. To restore the original image, click the " Restore " button (Ctrl+Z) on the toolbar. Back to www.ccqmap.com

QMap - Geodetic Control Point (GCP) Geometric fine correction

Image
The purpose of geometric correction is to map an image without geodetic coordinates to a given coordinate system. Through mapping transformation, it can eliminate the deviation of image geometric position caused by various factors, such as extrusion, stretching, distortion and offset, etc. It is especially suitable for remote sensing images and stitching of various super large images. Through geometric correction, precise positioning images of various geographic information can be established, which makes the analysis of historical changes with time as the axis very convenient. Now according to the software function interface, the introduction is as follows: 1. Load control point file     Click the "Load" button to load the selected geodetic control points with features. The control points to be selected are listed in the list box at the top of the dialog. 2. Match Control Points      Click an item in the list box at the top, and the details are listed in the ed...
