Add mono display support?

[ZhenyaKa]

Hi! Can you add mono display support? Need to size 3x times images by Y axis in "Printing file" panel.

[Nume1977]

Hi,
I have uploaded a new version. It scales the image preview on the print tab.
I am not sure it will scale your size correctly, but give it a try.

It shows printer pics at first layer and switch off (exits) after it

[Nume1977]

Sounds like a bug, going to investigate!
Could you please send a small cws file from your printer?

[Nume1977]

Please try the latest version. It should be more stable.
Some bugs are not caused by the manager, but bad firmware :(

[ZhenyaKa]

It still run out.

Here file that I try to print. Unpack it first :)
nova-plug_3DSLA_TestModel.mono.cws.zip

[Nume1977]

I have unpacked it and unpacked the cws (a zip inside a zip... inception!).
The image size is very weird, your printer has a 1620 x 2560 pixels display, but the slicer creates 540 x 2560 pixels images...
Really, why Nova?!
I can only see 2 options :
a) You loose 2/3 resolution on one of the axis, because the image is stretched from 540p to 1620p (540*3) .
b) The firmware centers the original image and fills the missing 1080 pixels.

Anyway, i now understand the source of the problem. I will implement on the next few days a check for the Y size, if it is below a certain threshold it will pre-resize the image before displaying it (and hopefully better).

At mono displays Nova3d uses 3pixels in rgb channels

[Nume1977]

DOH, now that i zoomed in an image the RGB is pretty obvious.
I will try to implement the decoding and see if it does not hog the cpu (I don't think java is ideal for this task).

[ZhenyaKa]

Java does it very quick

[ZhenyaKa]

you can use part of my code for that

` private static void pix2RGB(String fileName) {
try {
File file = new File(fileName);
BufferedImage source = ImageIO.read(file);
// Создаем новое пустое изображение, сжатое по короткой стороне в 3 раза
BufferedImage result = new BufferedImage(source.getWidth()/3, source.getHeight(), BufferedImage.TYPE_INT_RGB);

             // Делаем двойной цикл, чтобы обработать каждый пиксель
             int widthMax = source.getWidth()/3*3;
             for (int x = 0; x < widthMax; x = x + 3) {
                  for (int y = 0; y < source.getHeight(); y++) {

                    int pix1 = source.getRGB(x  , y)& 0xff;
                    int pix2 = source.getRGB(x+1, y)& 0xff;
                    int pix3 = source.getRGB(x+2, y)& 0xff;

                    Color newColor = new Color(pix3, pix2, pix1);

                    result.setRGB(x/3, y, newColor.getRGB());
                  }
             }

            // Сохраняем результат в тот же файл
            File output = new File(fileName);
            ImageIO.write(result, "png", output);

            } catch (IOException e) {

                // При открытии и сохранении файлов, может произойти неожиданный случай.
                // И на этот случай у нас try catch
                System.out.println("File not found or file error");
            }

    }`

для этого можно использовать часть моего кода

Приветик! А поделитесь, если это возможно, полным кодом.
У меня есть такая матрица с HDMI, и я хочу попробовать засвечивать фоторезист для изготовления печатных плат в домашних условиях, и для меня было полной неожиданностью что картинку так просто не выведешь на дисплей.
