Abstract

Examples of methods, systems, apparatus, and machine-readable storage media are provided to facilitate access and control of a remote desktop of a remote machine by a windows web browser of a client device through a web server without installing proprietary plug-ins or protocols on the client device. A web server may translate user input requests from a web browser into input calls compatible with a remote desktop display protocol. The web server may receive remote desktop drawing commands from the remote machine and translate the remote desktop drawing commands into web browser drawing updates compatible with the windows web browser. A web server may communicate with the windows web browser via HTTP and communicate with the remote machine via a remote desktop display protocol.

Claims

1. A method of conducting a remote desktop session comprising:

receiving, at a server, a user input request from a web browser of a client device for access and control of a remote machine;

translating, at the server, the user input request into an input command to be utilized for communication with the remote machine;

receiving, at the server, a remote desktop drawing command from the remote machine in response to the input command;

translating, at the server, the remote desktop drawing command into a windows graphics drawing command by updating a portion of a windows graphics application programming interface (API) memory bitmap, wherein the windows graphics API memory bitmap represents a portion of an image of a remote desktop of the remote machine that has changed relative to a previous graphics drawing command;

extracting, at the server, and from the windows graphic drawing command, drawing coordinates of one or more drawing regions from the remote desktop client; and

providing, at the server, the drawing coordinates to a drawing commands buffer, wherein the drawing commands buffer is configured to store an off-screen image onto which drawing commands are executed and to serve as a queue of coordinates for drawing commands.

2. The method of claim 1, further comprising providing, by the server, the windows graphics drawing command to the web browser.

3. The method of claim 1, further comprising:

generating, at the server, coordinates for the windows graphics API memory bitmap based on the windows graphics drawing command; and

forming, at the server, an image file including an image file based on the windows graphics API memory bitmap.

4. The method of claim 3, further comprising obtaining, at the server, drawing coordinates for the image file based on the coordinates for the windows graphics API memory bitmap.

5. The method of claim 4, wherein the drawing coordinates are compatible with HTML5.

6. The method of claim 4, wherein the web browser comprises client script code.

7. The method of claim 6, further comprising receiving, at the server, drawing requests from the client script code of the web browser.

8. The method of claim 1, further comprising receiving, at the server, asynchronous hypertext transfer protocol (HTTP) requests from the web browser, wherein the asynchronous HTTP requests comprise drawing requests.

9. A machine-readable non-transitory storage medium comprising instructions stored therein, the instructions executable by a processor, the instructions comprising code for causing the processor to:

receive a user input request from a web browser of a client device for access and control of a remote machine;

translate the user input request into an input command to be utilized for communication with the remote machine;

receive a remote desktop drawing command from the remote machine in response to the input command;

translate the remote desktop drawing command into a windows graphics drawing command by updating a portion of a windows graphics application programming interface (API) memory bitmap, wherein the windows graphics API memory bitmap represents a portion of an image of a remote desktop of the remote machine that has changed relative to a previous graphics drawing command;

extract, from the windows graphic drawing command, drawing coordinates of one or more drawing regions from the remote desktop client; and

provide the drawing coordinates to a drawing commands buffer, wherein the drawing commands buffer is configured to store an off-screen image onto which drawing commands are executed and to serve as a queue of coordinates for drawing commands.

10. The machine-readable non-transitory storage medium of claim 9, further comprising code for causing the processor to provide the windows graphics drawing command to the web browser.

11. The machine-readable non-transitory storage medium of claim 9, further comprising code for causing the processor to:

generate coordinates for the windows graphics API memory bitmap based on the windows graphics drawing command; and

form an image file including an image file based on the windows graphics API memory bitmap.

12. The machine-readable non-transitory storage medium of claim 11, further comprising code for causing the processor to obtain drawing coordinates for the image file based on the coordinates for the windows graphics API memory bitmap.

13. The machine-readable non-transitory storage medium of claim 12, wherein the drawing coordinates are compatible with HTML5.

14. The machine-readable non-transitory storage medium of claim 12, wherein the web browser comprises client script code.

15. The machine-readable non-transitory storage medium of claim 14, further comprising code for causing the processor to receive drawing requests from the client script code of the web browser.

16. The machine-readable non-transitory storage medium of claim 9, further comprising code for causing the processor to receive asynchronous hypertext transfer protocol (HTTP) requests from the web browser, wherein the asynchronous HTTP requests comprise drawing requests.

17. A system for conducting a remote desktop session comprising:

a processor configured to;

receive a user input request from a web browser of a client device for access and control of a remote machine;

translate the user input request into an input command to be utilized for communication with the remote machine;

receive a remote desktop drawing command from the remote machine in response to the input command;

translate the remote desktop drawing command into a windows graphics drawing command by updating a portion of a windows graphics application programming interface (API) memory bitmap, wherein the windows graphics API memory bitmap represents a portion of an image of a remote desktop of the remote machine that has changed relative to a previous graphics drawing command;

extract, from the windows graphic drawing command, drawing coordinates of one or more drawing regions from the remote desktop client; and

provide the drawing coordinates to a drawing commands buffer, wherein the drawing commands buffer is configured to store an off-screen image onto which drawing commands are executed and to serve as a queue of coordinates for drawing commands.

18. The system of claim 17, wherein the processor is further configured to provide the windows graphics drawing command to the web browser.

19. The system of claim 17, wherein the processor is further configured to:

generate coordinates for the windows graphics API memory bitmap based on the windows graphics drawing command; and

form an image file including an image file based on the windows graphics API memory bitmap.

20. The system of claim 19, wherein the processor is further configured to obtain drawing coordinates for the image file based on the coordinates for the windows graphics API memory bitmap.
