Change the size of the logo

This can be done with the cursor over the canvas or by directly entering the number of pixels. The first slider is the width of the canvas, the second it its height.

Use of color

Canvas logo maker colors

A sample can change both the text color, background of the logo or border of the text, if it is given one. First you click on one of the three input fields on the left:

Then you move the mouse over the circular sample and the inner squared sample to get a nuance. Then click on one of the three input fields to update the corresponding color. When one of the three fields is surrounded by black, and then selected and activated, you can directly change the color of the item by clicking on the sample.

You can also directly enter a hexadecimal color code in the input field.
In this case you must enter 6 hexadecimal digits or 3 digits, possibly preceded by "#", but it is not necessary. In the first case each pair corresponds to the values ​​red, green, blue respectively. In the second case each digit is doubled to form a pair and thus a component of an RGB color.

Example: 448800 or 480 correspond to the same color.

Font and text position

The text is shifted into the canvas by clicking the buttons or to the position x and y (horizontal and vertical).

A list of fonts is available, including Windows' ones. It can be extended by modifying the source code.

The text size is changed with a slider, like the canvas or by directly typing the number of pixels in the input field.

Adding a shadow

Check the box next to "Shadow" to display a shadow. This can be more or less separated from the text, and more or less diffuse. To do this, enter values ​​in the "Offset" and "Blur" on the same line.

Adding a border

The text can have a border whose thickness is specified in pixels and can be shifted from the text. Default offset values ​​are 0 and the edge is adjusted around the text.

The color of this border can also be defined by clicking the input field "Bord" next to the color swatch.

Adding a picture

When adding an image, it is behind the text. It does not replace the background, but if it is a texture, the image will be over it.

The button selects an image from the local file system. It can then be used in different ways:

The image is displayed as it is, cropped to fit the size of the canvas.

The image is resized to the size of the canvas and serves as a background. It can lose its proportions.

The image is added to the sample of textures and can be used as such.

Using textures

As the colors, textures can be applied to the bottom of the text or logo. Tick ​​the appropriate box and click on a texture.

If you have checked "Transparent background" next to the color samples, the texture is obviously not displayed.

When choosing a texture, this replaces the background color. Conversely, when choosing a background color, it eliminates the texture.
