How to change the 2D array's size of a picture

I have read a jpg picture by LabVIEW and got 2D array data of it .

Now ,I need to change the size(the real pixel size , not the size shown in front pannel).

I have two method, one is to use array modules , one is to change the size of the 2D array, the other method is to resample the picture when reading it . But , each method is difficult for me ,I can not find the blocks from Labview back panel's modules. 

I had also seen the page https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z0000019Ko3SAE&l=zh-CN,but nothing is done, because there are so many blocks ,(灬ꈍ ꈍ灬) .

any suggestion will be appreciate .
