BMP to
CIF/GDS/DXFWe convert various bitmap formats, e.g. BMP, TIFF, GIF, JPEG into GDSII/CIF/DXF formats. We also merge multiple bitmap files into one single GDSII/CIF/DXF file. Customers only need to tell us the final size of the images on masks.
For example, if your image has 2,400x2,400 pixels, and you want the final size on the mask to be 24,000 x 24,000 microns, then the size of each pixel should be 10 micron.
As GDSII format provides only black and white information, and most masks are binary, i.e. either opaque or not opaque. Hence, if your image is grayscale, we have to convert grayscale to halftone, and the grayscale values will be represented by the density of black subpixels. The number of black subpixels is determined by the grayscale values. For example, if the grayscale value of a certain pixel is 255, i.e. the pixel is white, then there will be no black sub-pixels within the pixel area. By contrast, if the grayscale value of a certain pixel is 0, i.e. the pixel is black, then the pixel area will be full of black subpixels. And if the grayscale value of a certain pixel is 128, half of the pixel area will be black subpixels.
