Hello everybody, I am a newby. I would like to implement a plugins or maxscript plugin to make a color correction for bitmap or other type of map. However, i am very very new and i dont know where to start. I tried to start doing it with MAX SDK however i didnt find too many resource and help about it so i prefered to do it with max script because i found more help about it. Please i will be very grateful if anyone could give me some advices and guides.
I have already started to write few lines of codes, it is just a script and not a script plugins. Please read the code and tell me how i can fix some problem with it. One of them (problem #1) is about keeping the aspect ratio of the opened bitmap, and the other one it is related with print (problem #2).
Also, I would like to know if there is a way to optimize the memory use such as freeSceneBitmap() or something like that to free the memory used by the loaded bitmaps.
Thank very much in advance,

Can you explain what exactly do you want to achieve?
MAXScript is probably too slow to do complex bitmap operations, and there is already a ColorCorrect map by Cuneyt Ozdas available for download which might do some of the things you need.

The SDK would be the right way to go if you intend to do heavy bitmap processing.
MAXScript can be used (if you want to learn and experiment with bitmaps without dealing with the SDK), but might not be practical if you intend to use the resulting tool in a production pipeline.
Hi Bobo, thank very much to reply my post. What, I am trying to do it is exactly the same as colorcorrection, however i would like to do with more user friendly interface. I am doing that just for LOVE. I always wanted to do learn maxscript or maxsdk however i never find an excuse. So one of my friend sugested to me to do an improved color correction. I dont expecto to achieve, but i would like to try to do one by myseld. Also, I would like to excuse my english, because it is a little bit rusty. Also i have some doubt with function in maxscript. I would like to pass as parameter a bitmap to fill it with the result of the histogram but it give me a error and i dont know why. I am trying to do that as reference. But it doesnt work properly.
Thank in advance,
ting

Ok, how about extending the existing colorcorrect texture – replacing the UI of the map with your own, more user-friendly one, while still using the underlying functionality Cuneyt has explosed in his plug-in?
Of course, you are free to implement your color correction code if you want to learn that part, too… But you should realize you will not be able to create a scripted texture map plug-in that does the same – it will have to stay as a separate tool, unless you decide to use the SDK. (scripted texture map plugins can only extend existing ones, but cannot implement their own shading code!)
