Ideally, we could work with 16bit source files all the time. Yes, while that is true, the problem is that often in our art, we are only using a small sub-set of colours and often with a gradient, this is where you will notice the limitations the most.Īs you can see in the image below, the gradient in the sky becomes heavily degraded when we use 8bit. If you're interested in understanding more about the above, check out the Wikipedia page on colour depth. Let's first outline 2 facts: 8 Bit colour has 256 shades of Red, Green and Blue for a total of 16,777,216 colours (256x256x256) 16 bit colour has a whopping 65,536 per channel! That means a total of… a lot. If you have a little understanding of bit depth you might think that, since a jpg file is only 8 bit, there's no benefit to working in 16 bit if you're saving your image as a jpg. Instead, I want to show you the benefits of working in 16bit. I don't want to get too technical in this article as you'll find plenty of information online about it. Arduino C-source hack, will replace some 0xFF with 0xFE so that the C-source can be downloaded to the Arduino Flash.Bit depth refers to the number of variations of a single colour (Red/Green/Blue) which can exist in your image.

Convert to C-source code (16-bit 565 top-bottom bitmap), will convert the image to 16-bit and then store it as a C-source file.Convert to C-source code, will take the 24-bit bitmap and create an array C-source file.Photoshop is one of the programs which can create it. This file can be read by many programs, but not many programs can create this file. It will have reversed row order (top-bottom).Destination file:Ī file with the same image information will be created: Have to be a 24-bit bitmap with row order bottom-top. With raw data, the program must already know this.ī, It is a standard so it can be viewed directly in most viewer (although not all viewer )Ĭ, Can create and edit the images in advanced photo editing programs like photoshop. Most embedded TFT uses the 16-bit 565 format and support the top-bottom write order.Ī, The MCU does not need to convert the 24-bit to 16-bit 565, this is already done.ī, If the source format is already in correct order, a faster algorithm for reading the data can be used.Ĭ, There is less data to read (because the image is only 2/3 of an original size)Ĭompared to raw picture data there are several advantages:Ī, It has meta data about the format, size, how it is stored etc.

The image is only 2/3 of the original size and because most embedded displays/drivers uses 16-bit color, the picture quality will be the same. There are 2 reasons for converting your images to 16-bit bmp with flipped row order:

msi: DisplayModule's Image Converter (.msi file zip DisplayModule's Image converter 1.0, smaller download size) Put the bmp on an SD-card and use DmTftLibrary to display the images on your display. Choose the destination directory and convert.ģ. Choose the 24-bit bmp you wish to convertĢ. This program will convert a 24-bit bmp (the most common variant) and convert it to a 16-bit bitmap.ġ.
