Draw Menu: Bitmap

To add a photo, users may select command “Bitmap” in the Draw Menu or click icon in the Toolbar.

Then the system will pop a dialog box as Figure shows to open a graphic file.

The current supported graphic file formats are: Bmp；Jpeg, Jpg；Gif；Tga；Png；Tiff, Tif；

Show Preview: When users select a graphic file, there will be a preview displayed in the dialog box.

Put to center: put the photo’s center in the origin.

When finishing adding a photo, a “Bitmap” parameter setting will appear in the Property Toolbar as Figure shows.

Dynamic file: whether to reread files when in process.

Fixed DPI: When selected, the system will fasten the unfixed DPI of dynamic photo. The higher the DPI’s level is, the closer the dots gather; and the photo’s precision is better, then the marking time is longer.

DPI: dot per inch; 1 inch is about 25.4 millimeters.

Fixed Size X: When checked, the width of the dynamic photo will be preserved in an appointed size, and if unchecked, the photo’s width will be the original size of the photo.

Fixed Size Y: When checked, the height of the dynamic photo will be preserved in an appointed size, and if unchecked, the photo’s height will be the original size of the photo.

Fixed position: the benchmark the dynamic photo based on while in size changing.

Image Manipulation:

Invert: run negative effect on photos.

Gray: change color photos into grey of level 256.

Dither: This effect is similar with the function “Grey Adjust” in Adobe PhotoShop. It uses color black and white to simulate grey image, so as to achieve a grey effect with dots arranged in different densities, as Figure shows. (The white bar in the photo was caused by display,
which will not be marked.)

Click the “Extend” button to run the “Bitmap” dialog box.

Lighten: adjust the current image’s brightness and contrast values.

Scan Mode:

Bidirectional Scan: the scan mode is bidirectional when in marking process.

Mark Mode:

Drill mode: whether the laser is kept on or restricted in appointed time for each dot’s marking when in process.

Adjust Power: whether the laser’s power is adjusted according to each dot’s grey level when in process.

Extend Parameter:

Y Scan: The scan will run along Y axis line by line.

Scan line Increment: This item indicates whether to scan line by line or skip some lines. This function may quicken the marking speed when in low precision marking requirement.

Disable Mark Low Gray Point: This item indicates that every point is marked or only marking bigger gray points. This function may quicken the marking speed when in low precision marking requirement.

Line feed malposition: The point isn’t aligned between two adjacent rows, but the point is aligned with the position which is the middle of two points in the previous line, to avoid the trace of marking.

Gray-Power figure: For improving marking results, can modify some of the gray scale corresponds to the power.

Optimize Mode: calculate the marking speed according to the DPI and frequency to optimize marking speed and result.

BiDir Offset: improve the edge not alignment marking problem.

ACC.Distance: this parameter is used for remove the offset of BiDir scan model.
