When are we supposed to use textures?
First of all, this is a very subjective question, the first should be determined by personal judgment: such as large area of color, background, need to be consistent lines and so on, for me, because of computer memory and time reasons, one of the clones is not a good way
Second, when we sometimes need to imitate an effect, we may not be able to determine whether the original image is using a texture fill, then I think the best way is to experiment. Of course, the prerequisite is that your time is full. If unfortunately there is no time, and experience is not very sufficient conditions. Please use one of the invincible imitation Dafa-magnifying observation
Here I provide a gadget-- Takecolor.rar , which not only can be enlarged, the magnification can be adjusted, but also can be color (the default button alt+c). Using this tool, you can easily see if the original image is using a texture, mainly using the comparison method.
Like this graph, at the very least, the segment uses textures (or textures) because each of its borders is consistent and the pixels in the small rectangle are closer, but why is it a bit different? Because this is only a JPG lossy compressed file, it will inevitably have differences.
Take the diagram above as an example, how should this texture be removed? We need to practice using the naked eye to judge: (Of course also can use tools, I like to use tools, the naked eye of the advantage is can improve your proficiency, save your time, to the veteran troops.
You can use the cutting function of this tool to determine a very perfect and reasonable texture range: p need to be carefully debugged, if combined with the visual observation of the efficiency of a large increase.
The above diagram, I cut the texture range as follows:
In order to achieve the three-dimensional effect, I have modified the following:
And then fill in the diagram that you made:
In which, the fill is not just filled in is finished, but also need careful adjustment, this adjustment of some parameters and attributes, I will post it out below.
Entire source file:
Draw a rectangle and set the gradient parameters and angles according to the diagram (to reflect the difference in texture in different colors):
After painting, note that the first figure, the texture is selected grid line 5, the corresponding file is:
Your FW installation directory \configuration\textures\grid 5.gif
OK, remember this, and then set the value next to the gridline to 100-the value is the strength of the texture fill (note that the texture fill is different from the FW pattern fill, and I'll write it later).
That's the effect:
Now we open this texture file. The path is already marked on it, because it is quite small, I magnified it to 5,000% 50 times times, which is the following:
The attentive reader has found out. This document is clearly black and white more, then why the texture fill, strength 100% is black more white less? Hey, that's the biggest difference between a texture fill and a pattern fill. Try to tune the strength you just said to 10.
You will find that the original strength is to control its transparency Ah! Yes, it's the transparency that controls it.
Moreover, the texture fill is a process of image blending, which I am based on constant experimentation.
According to the principle of the program, any color control is achieved through the operation of mathematics (also can say function), should be the result of a mixed image.
The research in this area is Soskitty. I don't sell running water in front of the Dragon King in my math grades.
test Works show :
The above results are derived from the following source file:
The main method is to control the mixing effect of the third layer inside. The third level of padding is the Web jitter (as for why, press CTRL + A in this post and then look at the picture). A little bit more, you move the third layer up 10 pixels. Try, see what?
