Image Extraction Software

Here I'm using a 7.5-inch e-inked screen for the test

How to Make Picture

This URL provides a very convenient image extraction operation, which can easily help us realize displaying a variety of images on top of the e-ink screen, let's get started!

Step 1.Select image

First pick the image you want, try not to exceed the size of 800*480.

Step 2.Image Settings

Canvas Size(s)
- Canvas Size: Set the dimensions of the canvas. For example, 800 x 480 pixels means the canvas width is 800 pixels and the height is 480 pixels.
Background Color
- Background Color: Choose the background color of the canvas. Options include:
- White: White background
- Black: Black background
Transparent: Transparent background
- Invert Image Color
- Invert Image Color: This option is used to invert the colors of the image. When selected, the colors of the image will be reversed.
Brightness / Alpha Threshold
- Brightness / Alpha Threshold: Set the brightness value of the pixels, ranging from 0 to 255. Higher values make the pixels brighter; pixels below this value will turn black.
Scaling
- Scaling: Choose the scaling method for the image. Options include:
Original size: Maintain the original size
- Other scaling options (specific options may need further explanation)
Center
- Center: Choose whether to center the image on the canvas. Note: This option only works if the image is larger than the original size.

Replace the image code in this header file

Display Effect

Usage of the Image2lcd software

How to Make Picture

Use the build-in software Paint in Windows to create a picture with the same resolution as the screen you are using, and save it asBMP or JPG file;

Your picture resolution must be the same as the screen you are using, for example, 4.2-inch E-paper is 400 x 300 pixels, then you can not use the size of 300 x 400, it will cause the iamge2lcd output .h file with an extra 200 bytes.

The colors of the picture should be consistent with the standard colors of the drawing board that come with Windows.The color of the drawing board is as follows:

E-paper	Colors
1.54-inch E-paper - Dotmatix 200x200	pure black and white
2.13-inch E-Paper -Flexible Monochrome 212x104	pure black and white
2.13-inch E-Paper - Quadruple 212x104	black, white, red, and yellow
2.9 inch E-paper - Monocolor 128x296	pure black and white
2.9-inch e-paper - Quadruple color 128x296	black, white, red, and yellow
4.2-inch E-Paper - Monocolor 400x300	pure black and white
4.26-inch E-Paper - Monocolor 800x480	pure black and white
5.65-inch E-paper - Sevencolor 600x480	black, white, red, yellow, blue, green, orange
5.83-inch E-paper - Monocolor 648x480	pure black and white
7.5-inch E-paper - Monocolor 800x480	pure black and white
7.5-inch E-paper - Tri-Color 800x480	pure black and white

Bitmap Conversion

Step 1. Open Image2lcd.7z, extract it and open the application.

Step 2. Open the picture, select the "Output file type" as the "C array (*.c)", select the "Scan mode" as the "Horizon Scan", the other parameters setting is show in follows:

Epaper	BitPixl	Max Width and Height	Reverse color	Display mode
1.54-inch E-paper - Dotmatix 200x200	Monochrome	200x200	✅	Mirror left-right
2.13-inch E-Paper -Flexible Monochrome 212x104	Monochrome	104x212	✅	Normal
2.13-inch E-Paper - Quadruple 212x104	4 Gray	104x212	/	Normal
2.9 inch E-paper - Monocolor 128x296	Monochrome	128x296	✅	Normal
2.9-inch e-paper - Quadruple color 128x296	4 Gray	128x296	/	Normal
4.2-inch E-Paper - Monocolor 400x300	Monochrome	400x300	✅	Mirror left-right
4.26-inch E-Paper - Monocolor 800x480	Monochrome	800x480	/	Mirror left-right
5.65-inch E-paper - Sevencolor 600x480	256 colors	600x448	/	Normal
5.83-inch E-paper - Monocolor 648x480	Monochrome	600x480	✅	Mirror left-right
7.5-inch E-paper - Monocolor 800x480	Monochrome	800x480	✅	Mirror left-right
7.5-inch E-paper - Tri-Color 800x480	Monochrome	800x480	/	Normal

After set the Max Width and Height, it need to click the arrow to confirm.
Don't include head data.

Step 3. Click "Save" to save the the lcd output array as a file of .h.
