First, use the MFC CImage class to load PNG imagesTo test the effect of CImage drawing a PNG image, we use the software to intercept a 360 interface, and then use tools such as Photoshop to add a transparent area around the image and then save it as a PNG image file. The CImage is first loaded from the file, i.e. cimage* M_PIMGBK; ...... M_PIMGBK = n

PNG transparent support for web pages (IE6, IE7, and Firefox passed tests)The defect that IE6 does not support PNG translucent images brings great inconvenience to the web design.

The window implements a translucent gradient window, the window is dragged without moving a rectangular box, And the taskbar form button is hidden.As follows

First, whether they are PNG, JPG, or GIF format, they have one thing in common, they are all picture formats, which can be generated directly from common cartographic software such as PS. Below, we introduce the characteristics and differences between the three of them separately.

The whole idea is to use the text in Word as the exported variable ${} as a placeholder, then into XML, the 64-bit base code into the picture's placeholder ${}, and finally convert the XML document into a FTL document. Do the word, do not use WPS. First, Word will change the Chinese characters to become placeholders, such as: ${objectname}. Image processing is, casually put a picture in PNG format. Convert Word to XML format. Iii. Open the

Precautions:(1) If the image is in PNG format, you can omit the suffix in the code.(2) You can give the control a tag value, and then use Viewwithtag to get the control.(3) The upper and lower left and right movement of the transform is in accordance with the vertical direction of its upper and lower border movement, that is, if you rotate the control, then the upper and lower left and right is not the traditional up and down, but oblique up and down
