Png Image Did Not Start With Ihdr. Note that the png 1 0 and 1 1 specifications define only a single allowed value 0 for either the compression type or the filtering method. Png images are not 32 bit nor are jpegs.
It has been some time since i last looked into this project however this issue looks to me like misuse of libpng and c10t seems to have ignored the png size limitations set by the png standard itself according to the specification it should be 2 31. This signature indicates that the remainder of the file contains a single png image consisting of a series of chunks beginning with an ihdr chunk and ending with an iend chunk. When you do this a dialog will appear hdr toning and your picture will look horrible.

The output of the code in console is. Also tried opening in paint but can t display and tried changing the file name to jpg or jpeg. If we were interested in whether the image is interlaced or what compression and filtering methods it uses we would use actual values instead of nulls for the last three arguments to png get ihdr. On a 32 bit machine e g go playground int is int32 in retrospect i should have probably used int32 in the struct or come to think of it uint32 could have been a better choice.
