Free software Paint.NET is not as powerful as many others. However, you can easily make a transparent background in a picture with it.
So, you need a certain object in the image to have a transparent background instead of the existing one. All methods have a similar principle: areas of the image that should be transparent are simply removed. But taking into account the peculiarities of the original background, you will have to use different Paint.NET tools.
Method 1: Selection "Magic wand"
The background that you will be removing must be selected so that the main content is not affected. If we are talking about an image with a white or the same type of background, devoid of various elements, then you can use the tool « Magic wand» .
- Open the image you want and click "Magic wand" in the toolbar.
- To select a background, just click on it. You will see a distinctive stencil around the edges of the main object. Examine the highlighted area carefully. For example, in our case "Magic wand" captured several places on the mug.
- In some pictures, the background can be viewed inside the main content and is not immediately highlighted. This is what happened with the white background inside the handle of our mug. To add it to the selection area, click "Union" and click on the desired area.
- When everything that should be transparent is selected, press "Edit" and "Clear Selection", or you can just press the button Del.
- It remains to save the result of your labors. Click "File" and "Save as".
- To preserve transparency, it is important to save the picture in the format "GIF" or "PNG", the latter being preferred.
- All values \u200b\u200bcan be left as default. Click "OK".
In this case, you need to slightly reduce the sensitivity until the situation is corrected.
As you can see, the stencil now runs exactly along the edges of the circle. If "Magic wand" on the contrary left pieces of the background around the main object, then you can try to increase the sensitivity.
As a result, you will get a background in the form of a checkerboard - this is how transparency is visually displayed. If you notice that somewhere it turned out unevenly, you can always undo the action by pressing the corresponding button and eliminate the shortcomings.
Method 2: Cropping by selection
If we are talking about a picture with a varied background, which "Magic wand" will not master, but at the same time the main object is more or less homogeneous, then you can select it and cut off everything else.
Adjust the sensitivity if necessary. When everything you need is highlighted, just press the button "Crop to Selection".
As a result, everything that was not included in the selected area will be deleted and replaced. transparent background... All that remains is to save the image in the format "PNG".
Method 3: Selection with "Lasso"
This option is convenient if you are dealing with a non-uniform background and the same main object that you cannot capture "Magic wand".
These simple methods of creating a transparent background in a picture can be used in the Paint.NET program. All you need is the ability to switch between different tools and care when selecting the edges of the desired object.

How to make a light flare in paint.net?
Here we will look at a rather simple and effective moment, how to make a highlight on an image using Paint.NET. This question is not accidentally posted in the section Paint.NET lessons for beginners, because it is performed in one step.
We will create a sun flare on a volumetric emoticon, which can be drawn in the lesson Paint.NET - How to create a funny three-dimensional emoticon in Paint.NET. We'll use the Paint.NET Gradient Tool to paint the highlight.
So, let's choose white as the main color, and set transparent as the secondary color. To do this, the parameter "Transparency (alpha)" in the palette window in Paint.NET must be set to 0. In the above figure you can see that this parameter is located in the lower right corner. In the figure, the value of this parameter is indicated as 225, because the figure is represented for the main color - white, which is not transparent. Select the type of gradient - circular, as it looks like you can see in the above picture in the upper left corner. And using the left mouse button, make a gradient in the place of the image where the color highlight should be. The result that we got can be seen in the picture below. We specifically saved the gradient markers in the image below.
How to make a drawing with a transparent background in paint.net? How do I change the white background color to transparent?
If you want to make a picture with a transparent background, for example, in order to place it on the site, then, first of all, you can immediately draw the image on transparent layer in Paint.NET. If you already got a picture, for example, with a white background, like the butterfly in the picture, then you will first need to remove the white background.
To remove the background, you can use, for example, the "magic wand" tool, in our example on the far left image. After the area necessary for deletion is selected - the middle picture, by pressing the Del button, you can delete it. If, as a result, you see a checkerboard pattern below the image, as in the far right picture, this means that the area of \u200b\u200bthe image in which you see the checkerboard pattern is transparent.
Note, that transparent background is supported by the two main formats PNG or GIF. If you save an image with a transparent background, such as JPG, Paint.NET will replace the transparent background color with white, because JPG does not support transparent images.
Which is better PNG or GIF format? Both of these formats support transparent colors and can be used for display in modern internet browsers. Unlike the GIF format, the 32-bit PNG format supports not only transparent colors, but also semi-transparent tones. On the other hand, transparent colors in images in 32-bit pNG format are not always displayed correctly in old Internet browsers, for example in Internet Explorer 6.
How can I reduce the selected image while maintaining the aspect ratio?
In some cases, when reducing or enlarging a selected area of \u200b\u200ban image, it is very important not to change the proportions of the original image. The picture below on the left is the original image - a green ball. If we do not want to get a reduced image, such as in the upper right corner in the same figure, resize the selection while holding down the Shift key.

With the help of this transparency, you can also make various templates and frame blanks that can be used later.
So, if you have an operating room windows system XP, the standard Paint will not work. This application does not have the ability to create transparency in the stage. To do this, you need to download from the Internet new version, which has greatly expanded its graphics capabilities - Paint Net.

Having created the work area, you need to simply select the entire work area, select the desired area for transparency. If you want to make the entire sheet transparent, then you need to select the entire area by pressing Ctrl + A and delete the selected area with the Del key. Thus, everything on the sheet is removed and a transparent base is obtained.
Now, having received this view of the window, you can start drawing on this workspace using any tools that this application offers.
So you are done drawing on the stage. Now the question arises - how to save this image? In order for transparency to be preserved in the image, it is necessary to save it not in JPG format, but in a special format that allows you to preserve the detail of the image, up to transparency - PNG.
