Hi,
I have a question. i have base64 string which contain image
image_control = Uncrypt(based64_string, "", cryptNone)
it seem work but there are few image not display out.
I have tested the base64 string on this site http://codebeautify.org/base64-to-image-converter
the image showing correct but not showing in image control.
am I missing some step before assign to image control? |

Hi
I haven't tried this, but I would put the result of the uncrypt into a buffer, THEN set it in the image.
Best regards |

Hi,
I have used your base64string, but I think this is cutoff and the original string is larger.
When I use this code
MyImage is Image MyImage = Uncrypt(gsBase64Image,"",cryptNone) IMG_NoName1 = MyImage
I get the following displayed:
[attachment 1892 Screen1.png]
I have used this before to display images in base64 format, and I have had no trouble displaying the images. Make sure that it is a supported image format on android (JPG, PNG, BMP, GIF, WebP)
I included the test project as attchement (Remove the .GIF extention)
Good luck !

Hi,
Probably my mistake, I copied the string again and now this is shown.
[attachment 1895 screen2.png]
So it should work correctly !

Hi Danny,
I can't get it work on my phone or tablet which is running android 4.2.
I think but I found the cause
I did test crypt() and uncrypt() and found the last 4 bytes (AE 42 60 82) is loss
m_file = fLoadBuffer(image_file)
BufferToHexa(m_file) -> AE 42 60 82 is exist
M_img64 is buffer = Crypt(m_file,"",cryptNone)
m_buff is buffer = Uncrypt(m_img64,"",cryptNone)
BufferToHexa(m_buff ) -> AE 42 60 82 is gone
some bytes in the contain may or may not loss. i can only notice the last
I in deep shit because this bugs, I don't know how many images in database corrupted |
