QMap - Image Transparent blend

Image transparent blend is a useful tool to perform relational operations between sub-images and background images, change the shape of sub-images, change the transparency, and finally merge into the background image.

Now according to the software function interface, the introduction is as follows:

1. Click the right mouse button to select the image
     Open two images, select them as sub-image and background image respectively, and then right-click on the background image to select the display position of the sub-image.

2. Color max and min limits
    Since sub-images are fused, we want to remove some of the brightest or darkest background colors to make the fusion effect better, so limiting the maximum and minimum values can meet our requirements.

3. Hide background(BK) color
    Generally, the default background color of the sub-image is black. When the background color is not black, the background color of the sub-image should be removed during fusion. You can use the Hide background color, click the color selection button, and select or enter the color value to achieve the purpose.
4. Subimage shape
    When sub-image and background are fused, different shapes can be selected to suit different requirements. Specifically, there are rectangles, rounded rectangles, ellipses, circles, etc. to choose from.

5. Relational operation
    When two images are fused, there are many operation methods between pixels, such as AND, OR, XOR, negation, addition and subtraction, etc., which can be selected according to actual requirements.

6. Transparency option
    When the transparency is selected as 0, it is opaque, when it is 100%, it is fully transparent, and the default is 50%.

7. After clicking the Process button, a new window will pop up to display the fusion effect.

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...
