Abstract

Various embodiments include a method and system for application above-the-fold rendering measurements. A start time corresponding to a rendering operation of an application may be recorded. A series of bitmaps of a portion of a rendering canvas representing above-the-fold data for the application may be captured. The first of the series of bitmaps may be captured at the start time and successive captured bitmaps each captured after a specified time interval from a previously captured bitmap. Each bitmap in the series of bitmaps may then be processed to create a corresponding measurement image, and the measurement images may be compared to determine an end time.

Claims

1. A method comprising:

recording a start time corresponding to a rendering operation of an application;

capturing, using one or more processors, a series of bitmaps of a portion of a rendering canvas representing above-the-fold (ATF) data for the application, a first captured bitmap being captured at the start time and successive captured bitmaps each captured after a specified time interval from a previously captured bitmap;

processing each bitmap in the series of bitmaps to create a corresponding measurement image, the processing including compressing each bitmap to create the corresponding measurement image; and

comparing measurement images to determine an end time, the comparing including locating a first measurement image that is equivalent in size to a group of successive measurement images, the end time being a time associated with the first measurement image and the group of successive measurement images including all measurement images within a predefined period of time following the first measurement image.

2. The method of claim 1, wherein recording the start time includes requesting a web page, and wherein the application is a web browser.

3. The method of claim 1, wherein capturing the series of bitmaps includes associating a timestamp with each bitmap when it is captured.

4. The method of claim 1, wherein the compressing each bitmap includes converting a bitmap into a JPEG image.

5. The method of claim 1, wherein the predefined period of time is one second.

6. The method of claim 1, wherein the specified time interval is sixty milliseconds.

7. The method of claim 1, wherein the portion of the rendering canvas representing the ATF data corresponds to pixels rendered onto a display.

8. A system including:

a processor;

an initiation module configured to capture a start time that corresponds to a rendering operation of an application;

a bitmap capture module that executes on the processor and is configured to capture a series of bitmaps of a portion of an application'"'"'s rendering canvas that represents above-the-fold (ATF) data, a first captured bitmap is captured at the start time and successive captured bitmaps are each captured after a specified time interval from a previously captured bitmap;

a processing module configured to process each bitmap in the series of bitmaps to create a measurement image, wherein to process each bitmap in the series of bitmaps includes compressing each bitmap to create a corresponding measurement image; and

a comparing module configured to compare measurement images to determine an end time, wherein to compare the measurement images to determine the end time includes locating a first measurement image that is equivalent in size to a group of successive measurement images, the end time being a time associated with the first measurement image and the group of successive measurement images including all measurement images within a predefined period of time following the first measurement image.

9. The system of claim 8, wherein to record the start time includes requesting a web page, and wherein the application is a web browser.

10. The system of claim 8, wherein to capture the series of bitmaps includes associating a timestamp with each bitmap when it is captured.

11. The system of claim 8, wherein compressing each bitmap includes converting a bitmap into a JPEG image.

12. The system of claim 8, wherein the predefined period of time is one second.

13. The system of claim 8, wherein the specified time interval is one millisecond.

14. The system of claim 8, wherein the portion of a rendering canvas representing the ATF data corresponds to pixels rendered onto a display.

15. A non-transitory machine-readable medium storing instructions that, when executed by at least one processor, cause the at least one processor to perform the following actions:

recording a start time corresponding to a rendering operation of an application;

capturing a series of bitmaps of a portion of a rendering canvas representing above-the-fold (ATF) data for the application, a first captured bitmap being captured at the start time and successive captured bitmaps each captured after a specified time interval from a previously captured bitmap;

processing each bitmap in the series of bitmaps to create a corresponding measurement image, the processing including compressing each bitmap to create the corresponding measurement image; and

comparing measurement images to determine an end time, the comparing including locating a first measurement image that is equivalent in size to a group of successive measurement images, the end time being a time associated with the first measurement image and the group of successive measurement images including all measurement images within a predefined period of time following the first measurement image.

16. The machine-readable medium of claim 15, wherein recording the start time includes requesting a web page, and wherein the application is a web browser.

17. The machine-readable medium of claim 15, wherein capturing the series of bitmaps includes associating a timestamp with each bitmap when it is captured.

18. The machine-readable medium of claim 15, wherein the compressing each bitmap includes converting a bitmap into a JPEG image.

19. The machine-readable medium of claim 15, wherein the portion of the rendering canvas representing the ATF data corresponds to pixels rendered onto a display.
