Android Guide: How to draw text over bitmap SKOUMA

  1. The Android SDK doesn't come with any easy way to draw text on OpenGL views. Leaving you with the following options. Place a TextView over your SurfaceView. This is slow and bad, but the most direct approach. Render common strings to textures, and simply draw those textures. This is by far the simplest and fastest, but the least flexible
  2. Drawing on the surface of a bitmap is the same as drawing on a video display. To draw on a video display, you obtain an SKCanvas object from the PaintSurface event arguments. To draw on a bitmap, you create an SKCanvas object using the SKCanvas constructor
  3. We are going to use the font engine which is part of Android. The font engine produces an RGBA image which contains the shape of the whole text. Then the image is uploaded into a texture and next the texture is mapped on a rectangle. The rectangle geometry must have an appropriate aspect ratio defined according to the texture size
  4. This example demonstrates how do I draw text on imagein android. Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project. Step 2 − Add the following code to res/layout/activity_main.xml. Step 3 − Add the following code to src/MainActivity.java
  5. Hi, I am drawing some text on a Canvas, and on a Bitmap, respectively: protected void onDraw (Canvas canvas) { canvas. drawText (Canvas text, 10, 10, mPaint); Canvas singleUseCanvas = new Canvas (); singleUseCanvas. setBitmap (mBitmap); singleUseCanvas. drawText (Bitmap text, 10, 30, mPaint);. In the former case, the text renders as you would expect, while in the latter, it appears very.
  6. In onDraw(), after drawing the bitmap, draw a rectangle. // Draw a frame around the canvas. canvas.drawRect(frame, paint) Run your app. Notice the frame. Task (optional): Storing data in a Path. In the current app, the drawing information is stored in a bitmap
  7. Text Drawing. If we had to draw text ourselves, that would be super-tricky. Thankfully, we have several nice options: 12. drawText. On Android, we normally use TextView for all our text. However.

Android: Draw text to dynamically sized bitmap - Java

  1. imal use of OpenGL, at the very least to place your bitmap on the screen. I could be wrong here though as my only experience with Skia is using the GPU drawing side, which obviously requires OpenGL
  2. render text into black and white bitmap, convert it to texture and then use pixel shader to render actual text in DirectX using that texture as alpha source (I hope this explanation is clear). Now it depends what you mean by black and white bitmap. If it's 1 bpp bitmap then it will blow up any form of antialiasing done by DrawString/TextRenderer
  3. The setStrokeWidth () method sets the stroke width of the Rectangle. Finally,b I called darwRect () to draw the rectangle. I have also drawn the text using the drawText () method of the canvas and also called setTextsize () to change the size of the text. Step 1 Create a project like this: Step 2 XML file. Now you have text inside the rectangle.
  4. Rendering the Text on Top of Video. To render the text, it first needs to be converted into a texture, so that I can use it through OpenGL. Android provides the Paint API which allows you draw text on a Canvas. Canvas allows you to draw onto a Bitmap. The Bitmap can then be easily used as OpenGL texture

For static text: Generate an image with all words used on your PC (For example with GIMP). Load this as a texture and use it as material for a plane. For long text that needs to be updated once in a while: Let android draw on a bitmap canvas (JVitela's solution). Load this as material for a plane. Use different texture coordinates for each word I'm trying to draw text on a bitmap but the result is to display only the text on Google Map Marker! The bitmap I want to use as marker image is not displayed ( SPin = AR.GetApplicationDrawable(s & mSts) ) I'm surely doing something wrong with the mutable bitmap initialisation but I can't figure out what! My code is doing the following I'm not an expert on this subject just yet, but if you want the source code for an Android method to center text that you want to use with the drawText method of the Canvas class, I know that this code works in two places in my current Android app:. public static int getApproxXToCenterText(String text, Typeface typeface, int fontSize, int widthToFitStringInto) { Paint p = new Paint(); p. Detect touch and draw rect on bitmap. In last example Detect touch and free draw on Bitmap , the points are drawn on the canvas (also the bitmap) directly when user touch. In case of drawing square, the user touch on the screen to mark the start position, and move, and release on the end position. We have to keep displaying the updated square

To draw onto a canvas in Android, you will need four things: A bitmap or a view — to hold the pixels where the canvas will be drawn. Canvas — to run the drawing commands on. Drawing commands — to indicate to the canvas what to draw. Paint — to describe how to draw the commands. Get access to a Canvas instanc That will happen everytime onDraw has received a call i.e. something like:*/ Bitmap myBitmap = bitMapFac.update(); //where update returns the most up to date Bitmap //here you set the rectangles in which you want to draw the bitmap and pass the bitmap canvas.drawBitmap(myBitMap, new Rect(0,0,400,400), new Rect(0,0,240,135) , null); super.onDraw. Rendering text to a texture is simpler than what the Sprite Text demo make it looks like, the basic idea is to use the Canvas class to render to a Bitmap and then pass the Bitmap to an OpenGL texture: android code snippet: // Create an empty, mutable bitmap Bitmap bitmap = Bitmap.createBitmap(256, 256, Bitmap.Config.ARGB_4444)

How to work with Bitmap in Android Android 02.08.2017. A bitmap (or raster graphic) is a digital image composed of a matrix of dots. When viewed at 100%, each dot corresponds to an individual pixel on a display. In a standard bitmap image, each dot can be assigned a different color The following examples show how to use android.graphics.Canvas#drawBitmap() .These examples are extracted from open source projects. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example This example demonstrates how to draw text On image in Android using Kotlin. Step 1 − Create a new project in Android Studio, go to File? New Project and fill all required details to create a new project. Step 2 − Add the following code to res/layout/activity_main.xml. Exampl Last I checked, Android's software-rendering API didn't know how to let go of a Surface. So you can either render with GLES or with software on a given Surface, but not both. For your situation, you can probably just render text to a Bitmap, then render it like you do the logo And I have decided to write down about whatever demon of Android world I happen to victor over, so that you could escape it right away.

In this exercise, you are going to draw in a new row, below the text, and inside the clipRect, as before.. You first call quickReject() with a rectangle inClipRectangle, that overlaps with clipRect.So quickReject() returns false, clipRect is filled with BLACK, and the inClipRectangle rectangle is drawn.; Then change the code and call quickReject(), with notInClipRectangle The Android framework APIs provides a set 2D drawing APIs that allow you to render your own custom graphics onto a canvas or to modify existing Views to customize their look and feel.

I am trying to place white text at the bottom of a bitmap. bitmap.height - 50f, paint) I assumed that because I set the y value of the text to bitmap.height - 50, the text would align with the bottom of the bitmap (since textSize is 50f) However, in reality, the text does not appear at. Because we draw text on the bitmap, we don't want users to scale the bitmap so that the text becomes blurred. To prevent this, we'll limit the maximum scale of the text sticker to be 1.0 . And in order to create bigger text, a user would have to increase the font size OpenGL code to draw text on screen void print_bitmap_string (/*void* font,*/ char * s) { while (* s) { glutBitmapCharacter ( GLUT Finally came with lots of projects to help all android developers.

In the Android environment, there is whole set of graphics routines usually a Bitmap holds the pixels, a Canvas is where we can apply the draw calls (writing into the bitmap) and with this we can draw the primitives (text, lines,etc) with a paint which describes the colors, styles and so on. Since the Android developing platform is all Java, it. To draw something, you need four basic components: A bitmap to hold the pixels, a Canvas to host the draw calls (writing into the bitmap), a drawing primitive (e.g. Rect, Circle), and a paint (to describe the colours and styles for the drawing). Paint class holds the style and colour information about how to draw geometries, text and bitmaps. 1

A custom Bitmap with the size of camera or video frame will be used to draw POIs and will be placed into ImageView. Note Using android:scaleType=centerCrop is important because the frame's aspect ratio coming from Vision SDK likely does not match the aspect ratio of actual device First we need to define placeholder. We can use a TextView and set a drawable shape with some color for the placeholder. For the original image, we can use an ImageView. But we got a problem here.
