Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Currently, in a Windows system, there are many methods for capturing a screen of a current desktop, and a GDI (Graphics Device Interface) is commonly used, and besides, a screen can be captured by using a ddr and dxgi (supported by a system above Windows 7).
The GDI is mainly responsible for information exchange between the system and the drawing program and processes graphics and image output of all Windows programs. The GDI enables programmers to convert the output of the application program into the output and the composition of the hardware equipment without paying attention to the hardware equipment and the normal driving of the equipment, realizes the isolation of a program developer and the hardware equipment, and greatly facilitates the development work. Therefore, the screen capture for removing the self software image provided by the embodiment of the invention can be realized by adopting GDI.
The embodiment of the invention provides a screen capturing method, which comprises the following steps of:
step S101: and modifying the color scheme of the equipment where the software is located. After the device where the software is located is determined, the color scheme of the device can be modified; specifically, the primary process of modifying the color scheme is to implement a disabled DWM. Wherein dwm. exe is the system process defined by Microsoft for its Windows 7/Vista operating system, and is associated with the desktop. Desktop Composition for DWM is a new feature built on the basis of Composition engines. The visual effects provided are frosted glass frames, 3D window transform animation, window flipping and high resolution support.
In one embodiment, disabling the DWM process may be accomplished by first calling the DwmIsComplexionEnabled function to determine whether the current Desktop Window Manager (DWM) is in an enabled state; when in the enabled state, an enabling function such as DwmEnableComplexition is called to modify the current desktop window manager to the disabled state, and when the DwmEnableComplexition function is called, its parameter is set to DWM _ EC _ DISABLECOMPACTION. Therefore, the disabling process can be realized by the following procedure.
In addition, when the DwmIsComplexionEnabled function is called and it is determined that the current Desktop Window Manager (DWM) is not in the enabled state, i.e., the current Desktop Window Manager (DWM) is in the disabled state, the disabled state of the current desktop window manager may be maintained.
Step S102: and adjusting the transparency of the own software window.
In an embodiment, the setwindowoption function may be used to adjust the transparency of the software window, specifically, the code is setwindowoption (0.999). When transparency adjustment is performed, the transparency of the window may actually reach 0.001.
Step S103: creating an equipment description table and a bitmap of equipment where own software is located; the device description table (DC) is a graph-wise (data) structure that defines a set of graphical objects and their attributes, affecting the output. windows provides a device description table for interaction between applications and physical devices, thereby providing platform independence for application design. The device description table is also called a device context, or device context. Specifically, the createcomapatibledc function may be called and the parameter set to NULL to obtain the screen dc (hdc).
In one embodiment, the CreateDIBSection function may be called to create a bitmap (bmp) that is compatible with screen DC. Specifically, the format of the created bitmap may be set, wherein the size of the bitmap may correspond to the size in the screen resolution, i.e., the width and height of the bitmap may be selected from the width and height in the screen resolution; in the bitmap, a pointer named bits can be transmitted for acquiring an image data memory; meanwhile, data of a specified screen image data format can be stored in the bitmap, and the capture screen image format can be specifically specified to be a 32-bit RGBA format.
Among them, the RGBA format is a color space representing Red (Red) Green (Green) Blue (Blue) and Alpha. The first three values (red, green and blue) range from an integer between 0 and 255 or a percentage between 0% and 100%. These values describe the amount of the three primary colors red, green and blue in the desired color. The fourth value, alpha value, establishes the color's transparency/opacity, which ranges between 0.0 and 1.0, with 0.5 being translucent. For example: rgba (255, 255, 255, 0) then represents a completely transparent white color; rgba (0, 0, 0, 1) then represents a completely opaque black color; rgba (0, 0, 0, 0) indicates a completely opaque white color, i.e., colorless.
In an embodiment, after the device description table and the bitmap are created, the created bitmap may be used to replace the original bitmap, and the handle old bmp of the original bitmap is saved for subsequent recovery, which may be implemented by calling the SelectObject function.
Step S104: and capturing screen image data according to the equipment description table and the bitmap to obtain a screen image with the software image removed.
In one embodiment, as shown in fig. 2, this step may be implemented by the following process:
step S201: creating a temporary device description table; specifically, a temporary target dc (hdctarget) may be created, which is equivalent to copying the device description table, and subsequently captured images may be transferred into hdctarget.
Step S202: uploading the acquired screen image data to a temporary equipment description table; specifically, the image data of hdc can be transferred into hdc _ target using the BitBlt function. The parameter width is the width of the screen resolution and the starting point is the upper left corner of the screen (coordinates (0, 0)).
Step S203: storing the uploaded screen image data according to the link data in the bitmap; because the bitmap has a link for storing the image data, the screen image data can be stored in the memory bits according to the link. Its size is the height and width of screen 4, and its format is RGBA.
Step S204: destroying the temporary equipment description table; specifically, after the image is saved, the created temporary target hdc _ target may be destroyed. Optionally, before the destruction, verification may be performed according to the stored screen image data, and whether the screen image data is consistent with the screen or not may be determined.
Step 205: and executing the steps S201 to S204 according to the video frame rate in a loop. Specifically, the acquisition interval may be calculated according to a specified video frame rate, and the steps S201 to S204 are executed when the time point is reached, so as to acquire one frame of image data until the entire required image is obtained. Since the color scheme and transparency of the device where the software is located are adjusted in step S101 and step 102; while in windows7 Basic color schemes, a translucent window is not captured when HDC BitBlt is used to capture a desktop or region. Therefore, the image of the own software disappears from the entire image captured at this step.
In an embodiment, the RGBA screen image data may be saved as a picture to check whether the RGBA screen image data is correct, that is, the RGBA screen image data is verified to determine whether the RGBA screen image data is consistent with the screen.
In one embodiment, after the image capture is completed, the replaced bitmap can be restored according to the original bitmap; and destroys the created device description table and bitmap. Specifically, the above-obtained hdc and old _ bmp may be transmitted by using the SelectObject function, and the original bitmap that is replaced before is restored; while the bitmap bmp can be destroyed using DeleteDC destruction device hdc, using DeleteObject.
According to the screen capture method provided by the embodiment of the invention, the color scheme of the equipment and the transparency of the software window of the equipment are adjusted by determining the equipment where the software is located, and then the capture of the screen or desktop image is realized by creating the equipment description table and the bitmap, and the color scheme of the equipment and the transparency of the software window of the equipment are adjusted; while in windows7 Basic color schemes, a translucent window is not captured when HDC BitBlt is used to capture a desktop or region. Therefore, in the screen image captured by the screen capturing method, the image of the software per se disappears, and the software per se or the window per se is hidden. In addition, the screen capture method provided by the embodiment of the invention can be used in a Windows system, and can be used for removing the window image of the user when capturing the screen, so as to prevent infinite nesting and hiding the content of the window which the user does not want to see.
