[Delphi VCL] Delphi_715748 DL : 0: Delphi:Delphi放大缩小图片，使用GDI技术来实现，通过操作菜单，可实现载入图片的灰度化（黑白图像）、二倍图片放大、四倍图片放大（处理比较慢，会假死）、图片变亮、图片变暗等。程序只实现了上述几种功能，有些地方细节还需要继续优化处理，有空的朋友，利用你的Delphi技术，完善它。 -Delphi: Delphi zoom images using GDI technology to achieve, by operating the menu, you can achieve load images of gray (black and white image), twice for larger image four times larger image (processed more slowly, will feign death), pictures lighten, darken the picture and so on. Program only to realize the several functions, some details still need to continue to optimize the local treatment, free friend, use your Delphi technique, improve it.

[Delphi VCL] WaveFileParser DL : 0: A WAV file is binary file in the RIFF format, RIFF format enables the user to haev multiple information in the same file which can either be used or not. The information is stored in chunks, each chunk have its type (4 chars) and side (dword) so it can be skipped if you are not interested in the data or to be read the file. You can download the demo software that shows wave file in a signal display graph with functions as: paning, zoom, multiple audio channels and more http://www.com-n-sense.com/ftproot/SignalDisplay.zip (the zip file contains the wavefileparser component and signaldisplay component).
