Using Photoshop to make seamless mosaic background image

The so-called seamless mosaic background, that is, the entire image can be seen as a number of small rectangular image mosaic, and each of the small rectangular image without seam traces, the small image is also fully consistent. This seamless mosaic image in daily life is also very common, such as the floor of the upper floors of leather, wallpaper, pattern cloth, gift wrapping paper. Seamless stitching image is widely used in computer image processing, especially in some graphic design and Web page background. If you use it to foil the subject content, not only beautiful chic, and simple, and not waste a lot of time and space. The following is an example of making a texture pattern and a figure puzzle. The detailed steps of the texture pattern are as follows (the software is made in Photoshop 6 Chinese version as an example): 1. Create a new RGB file with a 80x60, 72 pixel/inch, and background color white. 2. Set the foreground color to sky-blue. Select the Airbrush tool from the Toolbox, select the brush shown in the following illustration (which can be transferred from a blending brush), and click the mouse to generate the pattern in the middle of the image as shown in the picture:

3, from the Drop-down menu select "Filter → other → displacement" command, in the Displacement dialog box set level of 40 pixels, vertical 30 pixels, undefined area for retrace, OK exit. 4. Select the Airbrush tool from the toolbox again and spray the same pattern in the middle area of the image as shown in Figure 2:

5, press "CTRL + a" key to select all the image content, and then select the definition from the Edit menu command, give it a name for "cloth texture", the selected area is defined as a pattern. 6, create a suitable size of RGB files, select the Fill command from the Edit menu, select the content in the Fill dialog box to use as "pattern", from the custom pattern Drop-down bar to select the "cloth texture" just defined, to determine the exit, complete the production of Jacquard pattern, fill the results as shown in Figure 3:

Character Puzzle

In everyday applications, we may also need to splice a selected figure or scene as a small image into a background image, in which case the seamless welder (seamless solder) filter in the KPT3 of the Photoshop plug-in filter group can be used to achieve the goal. The seamless welder seamless welding filter works by reading the information on the edge of the image marquee, reversing it to the opposite side, and then fusing with the selected part to eliminate the seam. Also note: Because the seamless solder filter is to read the marquee edge information, you pull out a selection, the selected frame and image edge of the space at least in the marquee size of more than 10%. The specific steps are as follows: 1. Open a character image of the RGB image file, using a rectangular box to select tools for the person's head, as shown in Figure 4. We will use this avatar to make a seamless mosaic of the background pattern below.

2. Select the seamless welder filter in KPT3 from the Filter Drop-down menu, and in the dialog box that appears, set "Mode" to "seamless welder", "Glue" to "Normal", "Opacity" to "100%", Drag the mouse in the preview window, look at the bottom left corner of the tip bar, so that "intensity" (strength) of about 50%, we can use the filter in the upper right triangle drop-down menu in the "Preview edge Matching" To preview the edge of the fusion situation, Then press the green button in the lower right corner to perform the filter function. Edit the Drop-down menu to select the Define Pattern command, give it the name "character image", and define the selected area as a pattern. Creates a new RGB file of the appropriate size, select the Fill command from the Edit menu, select the content in the Fill dialog box to use as the pattern, from the custom pattern Drop-down bar in the selection of the "character image", the result of the fill as shown in Figure 5, you can see the edge is well fused, no seams.
