Hello,

Im new to the site and was hoping some of you could help me,

I would like to be able to open a file locate a certain offset in that file and extract up to a certain part

the item type i would want to extract is PNG from offsets

171A


to


(This number is varied depending on what size the PNG is :S*)

so put simply

Open File > Read data > Extract (171A - (See Above*) > Save it as a PNG

Oh and if needed the image will always be 64x64

Thank you very much for any help!

推荐答案

FileStream对象应该可以满足您的需求。


如果是171A ;是你正在寻找的价值，你可以循环通过它直到找到171A，然后开始跟踪你所读的内容


如果171A是偏移地址那么你可能会使用Seek（）函数寻找0x171A，然后开始阅读/跟踪你所读的内容

The FileStream object should accomplish what you need.

If "171A" is the value you are looking for, you can cycle through it until you find 171A and then start keeping track of what you read

if "171A" is the offset address then you can probably use the Seek() function to seek to 0x171A and then start reading/keeping track of what you read

嘿谢谢你的回复，但我可以对这些类型的函数进行排序？请，


谢谢
