How to read bitmap image on Arduino Stack Exchange?

How to read bitmap image on Arduino Stack Exchange?

My bitmap image is 272*208 pixel monochromatic 1bpp image. I’m confused when the width I get from my image is 16 instead of 272, the height is corrected. And when I skip the bitmap header to get bitmap infomation, I got string of meaningless number in my text file. That was a very raw way of trying to read a BMP file.

How to draw bitmap on 128×64 OLED display Arduino?

Copy the array to arduino code In this example i will use miliohm.com logo that will be use to draw in OLED display. I use paint to resize the image. The resolution of OLED display i use is 128×64 pixel. So the size of image is not more than that. I resize image to 115×64 pixel. Save image as monochrome bitmap.

How to create custom bitmap graphics for Arduino?

Thus, our first task is to create a bitmap version of the graphics to be displayed or convert the existing image to a bitmap file. There are several tools that can be used for creation/conversion of bitmap images including, Corel Draw and Paint.net, but for this tutorial, we will use the Paint.net.

What is the drawbitmap function in GFX?

The GFX library, among several other useful functions, has a function called drawBitmap (), which enables the display of a monochrome bitmap image on the display. This function allows the upload of monochrome only (single color) graphics, but this can be overcome by changing the color of the bitmap using some code.

Can a bitmap image be read in one byte?

The image height is less than 256. Only the lowest byte of the 32-bit image height is read. It is a small bitmap but it will take a very long time to read when reading a single byte at a time. There are methods to improve performance but that is an answer to another question.

Where are image files stored on an Arduino?

The file and image information are stored in little-endian so that works just fine on an AVR. First of all I suggest you to read the full specification of the bmp file header (for instance on wikipedia ).
