Abstract

The method and system of the present invention provides for converting all RFQ documents to a common compressed format. The method includes receiving an electronic file for use in an RFQ; extracting link information from the file and storing the extracted link information in an output file, if the file is a text-based file; extracting ISO symbol information from the file and storing the extracted symbol information in an output file, if the file is a CAD file; converting the file to a raster image; compressing the raster image into an RFQ format file, whereby, if an output file was created, the output file is used to generate a separate display layer that will display extracted information, and whereby the separate display later is inserted into the electronic RFQ format file.

(c) if the received file is a CAD file, extracting ISO symbol information from the file and storing the extracted symbol information in the output file;

(d) converting the received file to a raster image; and

(e) compressing the raster image into an electronic RFQ format file, wherein if the electronic file is one of the text-based file and the CAD file, the output file is used to generate a separate display layer to display the extracted information in addition to information of the raster image, and wherein the separate display layer is inserted into the electronic RFQ format file such that the information of the display layer is displayed in response to an activation from the RFW format file.

2. The method of claim 1, whereby the text-based file is a PDF file.

(i) if the file is not a PDF file, converting the text-based file to a PDF file that includes the links;

(ii) extracting link information from the PDF file; and

(iii) storing the extracted link information in the output file, wherein the display layer is displayed overlaying the PDF file.

4. The method of claim 1, wherein the compression in step (e) is a wavelet-based compression.

5. The method of claim 1, wherein the raster image is in TIFF format.

6. The method of claim 1, wherein the raster image is in BMP format.

7. A system for creating compressed files for use in an electronic RFQ, wherein the system receives electronic files for use in the electronic RFQ, comprising:

means for inserting the separate display layer into the electronic RFQ format file such that the information of the display layer is displayed in response to an activation received from the RFQ format file.

8. A machine-readable medium that includes instructions for creating a compressed file for use in an electronic RFQ, wherein such instructions, when executed by a processor, cause the processor to:

receive an electronic file for use in an electronic RFQ;

extract link information from the received file and store extracted link information in an output file separated from the electronic file, if the received file is a text-based file with links,

extract ISO symbol information from the file and store extracted symbol information in the output file, if the received file is a CAD file;

convert the file to a raster image;

compress the raster file into an electronic RFQ format file;

generate a separate display layer that to display extracted information in addition to the RFQ format file; and

inserting the separate display layer into the electronic RFQ format file, if information was extracted from the file, wherein the display layer is displayed overlaying the RFQ format file, and wherein extracted information is displayed from the display layer in response to an activation from the displayed RFQ format file.

9. A method of compressing a CAD file that contains ISO symbols into an RFQ format file, whereby displaying the RFQ format file will cause the information stored in the ISO symbols to be displayed in a CTQ layer, comprising:

(a) receiving a drawing in a CAD file;

(b) parsing ISO symbol information from the drawing in the CAD file and storing the symbol information in a symbol output file;

(c) converting the drawing into a raster image;

(d) compressing the raster image to an RFQ format file; and

(e) inserting information from the symbol output file into the RFQ format file as a separate display layer, such that the symbol information is displayed as a CTQ layer in the RFQ format file.

10. The method of claim 9, wherein the symbol information stored in step (b) includes text descriptions of the symbols.

11. The method of claim 9, wherein the raster image in step (c) is TIFF format.

12. The method of claim 9, wherein the raster image in step (c) is BMP format.

13. The method of claim 9, wherein the compression in step (d) is wavelet-based compression.

14. The method of claim 9, wherein both symbol and text information for a symbol are displayed in the CTQ layer.

15. A system for compressing a CAD file that contains ISO symbols into an RFQ format file, whereby displaying the REQ format file will cause the information stored in the ISO symbols to be displayed in a CTQ layer, comprising:

means for receiving a drawing in a CAD file;

means for parsing ISO symbol information from the drawing in the CAD file and storing the symbol information in a symbol output file;
