android - Working with pixels and argb -


मेरे पास एक लूप है जो कि i & lt; Pixels.lenth तब जब पिक्सेल = बिटमैप .getpixels (..) । अब मेरे कोड में यह कोड है: 

  int argb = 0; Argb + = ((पिक्सल [x]> gt; 24) & amp; 0xff); // अल्फा आर्गब + = (पिक्सल [x] & amp; 0xff); // नीला argb + = ((पिक्सल [x] & amp; 0xff) & lt; & lt; 8); // हरे argb + = ((पिक्सल [x] & amp; 0xff) & lt; & lt; 16); // लाल पिक्सल [x] = argb;

समस्या यह है कि छवि ग्रे और बोल्ड (यदि किसी को भी जरूरत है तो चित्र जोड़ सकते हैं), शेष सामान्य की बजाय क्या कोई मेरी मदद कर सकता है? बहुत बहुत धन्यवाद

आप गलत क्रम में जा रहे हैं यह होना चाहिए: 

  int argb = 0; इंट अल्फा = ((पिक्सल [x]> gt; 24) & amp; 0xff); // अल्फा इंनाल्यू = (पिक्सल [x] और 0xff); // नीले ग्रीन हरे = ((पिक्सल [x]> gt; 8) & amp; 0xff); // हरी इंट लाल = ((पिक्सल [x]> gt; & gt; 16) & amp; 0xff); // लाल पिक्सल [x] = अल्फा & lt; & lt; 24 + लाल & lt; & lt; 16 + हरा & lt; & lt; 8 + नीला

c++ - How to load a bitmap from file into the samples buffer -

I am trying to add text to the bitmap obtained from the DirectShow filter. First of all I tried to use gdiplus, but that was not working so now I just call a net program that connects to bitmap. The problem is that I do not know how to reload the bitmap from a file into buffer samples in a direct save.

Media samples are a part of the agreement between filters on specific pin connections. You usually do not load media samples until y...

To do this, I had planned to store the information in the database and create the above array based on the results, by researching how to us...
