Currently, an ordinary user increasingly has to turn to the help of graphic editors, but as they say "demand creates supply" and the software market, in particular, graphic editors, is constantly improving. The variety of graphic editors, closely competing with each other, allows the user to choose the most suitable program for his professional needs.

There are two main types of two-dimensional computer graphics. It is vector and raster. Vector graphics represent graphic objects in the form of geometric primitives and allows you to scale objects without any loss of quality. Raster graphics builds an image from a collection of points, each of which has its own color. Each of the above types of graphics has its own advantages and disadvantages, and is also used for implementing different tasks. But in this work we will talk about raster graphics, namely, a program for working with raster graphics which is Corel Photo Paint 2019 [1, 2].

Corel Photo Paint 2019 is a powerful tool for creating, editing and viewing raster images developed by the Canadian company Corel. The program is distributed as an addition to the program CorelDraw (program for editing vector images). The editor is written in C ++. It supports basic graphic extensions such as JPEG, PNG, TIF, GIF, CPT (Corel Photo Paint), and can also work with the Adobe Photoshop - PSD extension [3].

Object Selection Tool

To begin with, I would like to discuss the tools that are on the left side of the program in the quick access panel (see Figure 1). I will describe them in order of their arrangement from top to bottom. All Corel Photo Paint tools have a panel with additional useful settings.

Figure 1 - Quick Access Panel

1) The first tool offered by the program is the Object Selection tool. In order to use it you push the hot key "O". This tool is designed to manipulate and transform objects. This tool can be used manually, or you just set the necessary parameters in the panel of additional settings (object position according to the coordinate system, length, width, angle). This tool combines 6 tools: position and size, rotation, scale, tilt, distortion and perspective [4].

Mask Tools

2) Below is a rectangular mask tool. Holding the tool button, you can see the tools included in the group of this tool.

Most group tools have four main modes: Normal mode, Additive mode, XOR mode, and Subtractive mode. The main mode is used by default. Additive mode allows you to add additional zones to the already selected. The XOR mode excludes areas that do not overlap with the selection areas (see Figure 2). The subtractive mode can work as an inverted selection.

3) Number 3 is the mask conversion tool. Hotkey for the tool is "M". This tool allows you to edit the selected area. Its' functions are similar to the Object Selection tool, but it is only applied to the selected area, and not to the object.

Cropping Tools

4) Next comes the Crop tool. This tool also contains a group of tools.

1) You use the key "D". With this tool, you can crop the image to a specific size. This can be done either manually or by setting the necessary parameters in the advanced settings panel. Also, in the advanced settings panel, you can select blanks for the main print formats (A2, A3, A4, etc.).

1) Straighten tool is a very useful tool for photographers. With it, you can straighten the image segment. The shortcut key is "SHIFT + X" (Figure 3).

Figure 3 - The Example of Using Straighten Tool

1) Correction of perspective allows you to slightly correct defects of perspective. The keyboard combination is "SHIFT + C".

2) Image splitting allows you to split large images into small fragments, which is very useful for web-programming. These fragments may also contain hyperlinks. The hotkey for tool is "6".

Scaling Tools

5) Number five is the Scale tool. Allows you to scale the selected area, or it can be used by pressing the left mouse button to zoom in and by pressing the left mouse button while holding down the SHIFT key to zoom out, the hot key of the zoom tool is "Z". The tool is not so often used due to the fact that the program can be scaled by rotating the mouse wheel, but is suitable for pinpoint zoom.

Retouching Tools

6) The Cloning tool is similar to the Stamp tool in Adobe Photoshop. To select a tool, you can use the key "C". At the first click, an area is selected, which will then be used as a brush. The tool offers different forms of brushes for a wide range of tasks. It has 4 operating modes: Impressionist cloning, Pointillist cloning, Cloning from the saved, Cloning from the fill.

Red-eye removal. The operation of the tool is clearly shown in Fig. 4. Hotkey for the tool is "5".

Figure 4 - The Example of Working with the Tool "Red-Eye Removal"

1) The retouching brush allows you to eliminate wrinkles, cracks and other defects in photographs by flowing textures and colors. The hotkey is "7".

2) Recovering cloning uses the built-in texture library to eliminate image defects. For a quick access to the tool use the key "0".

Tools for Local Color and Tone Adjustments

7) The Palette Knife tool is designed to blur the image. You can use the keyboard shortcut "Shift + S". There are two modes of operation: pointed and smooth palette knife. A pointed one uses curves with sharp angles, while a smooth one uses smooth curves. In additional parameters, you can change the size and pressure of the pen.

8) Number 8 is the Effect tool.

Text Formation Tool

9) The Text tool is a standard tool in all graphic editors. The hotkey for the text is also a standard letter "T". Using it, you can place text on the image. Options are also available for formatting texts: a standard set of fonts, changes of text sizes, colors, line spacing and character spacing.

Drawing Tools

10) Corel Photo-Paint provides a huge set of brushes for a wide range of tasks. Hotkey "B". The brush tool is divided into 15 different brushes, each of which contains different variations: brush, airbrush, spray, pencil, ballpoint pen, pen, felt-tip pen, marker, text marker, crayon, colored pencil, charcoal, watercolor pastel and art brushes.

11) The rectangle tool allows you to draw rectangular shapes. It can be selected using the key "F6". There are 5 types of fills for shapes to choose from: no fill, color fill, fountain fill, bitmap fill, pattern fill.

12) An eraser tool is a brush designed to remove parts of an image. Hotkey for the eraser is "X". If an object is selected, only the parts of this object are "erased". It has no varieties, but provides fine setting for the eraser brush: the ability to change the shape of the brush, size, sharpening, adjusting the thickness of the tip of the brush and the degree of rotation of the brush.

Tools for Creating Shadow and Transparency

13) Shadow tool. The hotkey is "S". A rather interesting tool that allows you to create shadows for selected objects. In order to create a shadow, you need to click and hold the object to which you want to give a shadow with the left mouse button. An outline of the object will appear, which will be the shadow of the object. After building the shadow, the tool interface appears (see Figure 5).

Figure 5 - Working with Shadow Tool

14) Changes the transparency of the object. There are 5 modes of operation.

- No transparency removes the transparency effect

- Homogeneous transparency imposes a transparency effect adjustable in percentage terms on the entire object.

- Fountain fill allows you to change the transparency parameter relative to the center of the line. Figure 6 illustrates the operation of the tool.

Figure 6. Working with Transparency Tool

- Transparency with a raster pattern creates a transparency effect by superimposing on top a raster pattern from the same library as the Rectangle tool.

- Transparency with a texture works the same as the previous mode, but differs in that it imposes a pattern from the Corel Photo-Paint library on the transparency effect, however, you can use any other textures in the .fill format.

Color Tools

15) Eyedropper is an important tool when working with graphics. We select color samples in the image and sets them as the primary color, in order to select the fill color we use the tool with the "CTRL" key pressed. In addition to the main mode, there are three operating modes: 3x3 (we select the average color value from the 3x3 pixel area), 5x5 (similar to the previous one, but in the 5x5 pixel area), sample selection (it displays the average color value in the selected area).

16) Fill fills the selected region or object with color, texture, or a raster pattern. The fill options are identical to the fill options for the rest of the tools, the rectangle tool in particular.

Also in the same group of tools there is another tool - this is Interactive fill. It offers more options for filling, for fountain (gradient) filling in particular. It allows you to select the angle and border of the transition between colors. The tool is used in the same way like the Transparency tool.

And now about the benefits, the program contains many interesting tools and there is a deep customization for each of them. In general, the program interface is quite satisfying. There are great opportunities for personalizing the program (you can freely move all the windows of the program, change all the hot keys, load additional tools). The program supports almost all modern graphic formats, including the .PSD format.

Given all of the above, we should summarize. Despite its shortcomings, the program is a worthy graphic editor, which is more suitable for ordinary users than for professionals. Since the program cannot be purchased separately from Corel Draw, the program can be called a fine addition to Corel Draw.
