>>>What is Sketch?

Sketch is a function that uploads an image like img2img explained in Section 1 and creates an image by giving instructions using the drawing function on the WebUI. The WebUI contains a palette and several tools like drawing software, so you can easily modify and supplement the input image without installing image editing software like Photoshop. You can also upload an image with a white background, draw a simple outline, and then create an image.

>>>Let's try Sketch

Open the img2img tab and click to select the Generation → Sketch tab.

First, prepare the image to be input, and upload it by dragging and dropping it into the blank space or clicking inside the area to select the file directly from the folder. You can also upload the image to PNG info and click Send to inpaint to send it. When the canvas appears, a tool icon will appear in the upper right corner, so use it to edit the input image.

Undo

Undoes the last action and returns to the previous state.

Clear

Deletes all previous content.

Use brush

Switches to the bot used in the WebUI. Clicking it again will bring up a bar to adjust the brush thickness.

Select brush color

Changes the color of the brush. Clicking it will show the currently used color, and clicking it will bring up a palette to change it to a different color.

Remove image

Discards the input image currently on the canvas.

Let's add Prompt blue eyes to the prompt, set other parameters, and click Generate to solve it. This time, I set Denoising strength to 0.4.

You can also create an image using only the Sketch function as a sketch. This time, let's draw a girl wearing a straw hat. It's easier to draw if you have a pen tablet, but you can also do it with a mouse. Once you've finished drawing the sketch, click the Generate button to create it. You can see that the illustration has been created with many of the features of the sketch, such as composition and color, reflected.

An image 100 times more beautiful than what I drew is born.
