Description: When I wrote this function my problem was to replace one color by an other on transparent bitmaps. My images were resources bitmaps, which I store in an ImageList for easy transparency.
There is no easy way to directly access a Bitmap s pixel on Win32. If you re interested in, this article may help you to understand the usage of CreateDIBSection.
If you have to load a bitmap from resource and made many color replacements, or if you have to change a color in a HBITMAP this function is for you.
If you have a bitmap in resource and want to replace one or more color on load, it s better to use CreateMappedBitmap. You can found in the sample program a ReplaceColor function which use CreateMappedBitmap.
I ve made the same code using only BitBlt. All BitBlt are really fast but the creation of the mask bitmap is so slow than the whole function is twice slower than the code using CreateDIBSection. ( sources are in the sample )

Description: 本程序在EVC4.0+PPC SDK 2003下调试通过。
用Independent JPEG Group发行的JpegLib进行Jpeg图像的读取与保存。
这里只加了一个简单的处理示例——负片。其他的处理可以用与这个类似的方法，有了处理的算法对像素数据进行操作。或者加上鼠标事件的处理来完成绘画功能等等，这里主要是对JPEG文件进行操作的部分。
注意：程序中的CTScreenBuffer并未使用，原因是使用它加载后有段内存没有释放，加上BMP数据本来就比较好处理，所以自己写一段，将BMP数据加上头信息就可以CreateDIBSection了。
保存的默认质量Q=85，大家在使用时可以按照要求改变。
对应的PC版可以在VC下面编译使用，是基本的图象处理程序框架。
-the procedures in EVC4.0 PPC SDK under debugging through 2003. Independent JPEG Group with the issue for JpegLib Jpeg image Read and preservation. Here are adding a simple example of the treatment -- Negative. Other treatment can be used with a similar approach, with the right algorithm pixel data for the operation. Mouse or with the handling of the incident to complete the painting functions, and so on, here are the major JPEG files part of the operation. Note : CTScreenBuffer the procedures had not been used. It is due to the use of loading after not release memory, coupled with BMP data was relatively easy to deal with. So he has written section BMP data will be coupled with the first information on the CreateDIBSection. Preserve the quality of the default Q = 85, we can use the request Platform: |
