Draw Menu: Bitmap

If you want to enter a bitmap, select the Bitmap command in the Draw menu or click the icon.

The system will pop up the input dialog and ask the user to select the bitmap to be input.

The current system supports bitmap formats: Bmp, Jpeg, jpg, gif, tga, png, tiff, Tif

After the user enters the bitmap, the property toolbar displays the bitmap parameters as shown in Figure.

Dynamic  input  file:  refers  to  whether  or  not  to  read  the  file  again  during processing.

Fixed size X: The width of the input bitmap is fixed to the specified size, if it is not automatically stretched to the specified size.

Fixed size Y: The height of the input bitmap is fixed to the specified size, if it is not automatically stretched to the specified size.

Fixed position: When dynamically inputting a file, if you change the size of the bitmap.

Fixed DPI: Because the DPI value of the original input bitmap file is not fixed, this function can be used to force a fixed DPI value. The larger the DPI value, the denser the point, the higher the image precision, the longer the processing time, and the value of DPI. 10-2000 When dynamically inputting a file, if you change the bitmap size, which position is used as a reference.

DPI: Refers to how many points per inch, 1 inch is equal to 25.4 millimeters.

Invert: Inverts the color value of each point in the current image.

Gray: convert the colorful bitmap to gray bitmap.

Dither: Similar to the "halftone pattern" function in Adobe Photoshop, a black-and-white two-color image is used to simulate a grayscale image, and different grayscale effects are simulated by adjusting the degree of density of the dots with black and white, as shown in Figure. (The vertical bar in the picture shows the problem, it will not appear when processing).

Lighten: Change the brightness and contrast of the current image.

Bidirection scan: Bitmap scanning direction is two-way scanning back and forth.

Drill mode: the processing bitmap is converted to a point, and the light emission time of each point is the current setting time, which is not ticked as the threading mode.

Pixel power adjustment: Refers to whether or not the laser adjusts the power according to the gray level of the pixel when processing each pixel of the bitmap.

Scan mode extend:

Reverse scan: The processing bitmap scans in the X-direction scan direction from the bottom up, select the reverse direction and scan from top to bottom.

Y scan: When the bitmap is selected, the Y direction is scanned one by one in a row, and the X direction scans one line at a time.

Scan line increment: interlace scanning according to the set interval, proper setting can improve processing efficiency.

Dis mark low pt: Setting the grayscale points below will not mark.
