![]() Finally I call context.fillText() to draw the text on the canvas: const text 'Hello, World' context.font 'bold 70pt Menlo' context.textAlign 'center' context.fillStyle 'fff' context. I align it in the center, then I set the color white. In this article, we will write a sample code to read and edit a GIF using canvas-gif for your next Node.js project. I first pick the Menlo font, big and bold. The function here is basic but you can expand it with color and background parameters as well as padding etc. Canvas-gif harnesses all the superpowers of Canvas, allowing you to manipulate every part of the image beyond just adding text to each GIF frame. You can use measureText to find out the width of the text (in the future also the height: ascend + descend) and use that as a basis: var width = ctx.measureText('My text').width /// width in pixels Generate backgrounds: Select the background behind your subject, then generate a new scene from a text prompt. Then draw the text on top: ctx.fillText('My text', x, y) With Generative Fill, you can: Generate objects: Select an area in your image, then describe what you’d like to add/replace through a text prompt. In order to create a background you would need to draw it first using other means such as shapes or an image.Įxamples: ctx.fillRect(x, y, width, height) This is not the case with vector based typefaces by default (a browser has direct access to the glyphs geometry and can therefor provide a background this way). Instead of just clearing the background one could opt to provide a background instead. Most of the AI image tools featured in this article use a mix of text prompts to generate the images. On the old computer systems most fonts where binary font which where setting or clearing a pixels. There is no layer for the black-box (the rectangle which the glyph fits within) the glyph is using besides from using its geometric position, so we need to provide a sort-of black-box and bearings ourselves. I don’t know what kind of programming background you have, but I’m still going to try answering your question. ![]() This is because the glyphs from the typeface (font) are converted to individual shapes or paths if you want, where the background of it would be the inner part of the glyph itself (the part you see when using fill). Answer: I’m not sure how or why you want to achieve this. External images can be used in any format supported by the browser, such as PNG, GIF, or JPEG. Unfortunately no, you can't produce text with background with the text methods - only fill or outline the text itself. The canvas rendering context provides two methods to render text: fillText (text, x, y, maxWidth) Fills a given text at the given (x,y) position.
