Hi,
The app I'm currently building in PowerApps utilizes a camera and pen input function, where in essentially you take a picture and you're then given the option to draw on said picture using the Pen Input function so as to add notes, annotations, etc. At the moment I have it so that when the picture is taken and the notes are added, both are added to Azure Storage as two separate images, and what I'm trying to do is merge them using a Flow, which receives all the information about the images, and then uses HTTP call to a free API called 'Convert API' to join them together.
Below is my Flow as it currently is:
For the most part it runs smoothly, however when it reaches the HTTP step, it fails with the below error:
"{"Code":4002,"Message":"Bad JSon format. The input is not a valid Base-64 string as it contains a non-base 64 character, more than two padding characters, or an illegal character among the padding characters. "}"
I'm thinking that the error is possibly coming from the HTML input that gets passed along, specifically the "data:image/png;base64," header, but I'm not 100% sure, and if it is that how would I go about removing it?
Any help would be appreciated - Thank you!
I think the issue here is with the additional source path that is being added.
Regarding the source path that you are getting in the content output, that is coming from the azure output where the data is being stored once you convert the data into base64() format you will get that source path added.
You can use the formula Mid(base64() value of the image, 24,Len(base64() value of the image) - 24)
Use this formula to get rid of the extra path information.

Thanks for the response - I'll give it a shot! Whereabouts in the Flow would I put the Mid formula? Would it be in it's own action entirely? Sorry if this is a stupid question, I'm not particularly adept at Flow or Powerapps!
You can put it in the place where you are converting the Azure Blob storage value to a Json data.
This will extract the path from that Json data.
The best idea in this scenario will be to declare a variable in flow of type string/json.
Store the Image Json data in the variable.
Then apply the mid() formula on output of that variable.
Mid(Output of variable, 24,Len(Output of variable) - 24)
Thankyou for your assistance so far - as advised I've now stored the data in a variable and used the mid() formula on it, which when looking at my output now appears to have removed the extra path information, however the Flow is still failing and I'm still getting the same message as before:
"{"Code":4002,"Message":"Bad JSon format. The input is not a valid Base-64 string as it contains a non-base 64 character, more than two padding characters, or an illegal character among the padding characters. "}"
There must be a junk character in there somewhere, but I'm having no luck finding it:
The only other thing that's occurred to me that could possibly be incorrect is the ImageHTML variable I've got in the Flow, and whether the DataURI Expressions I'm using are causing an issue:
If you have any input I'd be most appreciative.
Further to my last post, I've tested sending the Photo and Drawing variables separately to the API and both have been successful, so as I see it there's no issue with the base64 of the images themselves.
In which case, I think the issue comes down to my writeup of the ImageHTML variable, which includes both the Photo and Drawing variables (base64 makeup of both images) and the sizing information.
Can anyone helps me how to make pen drawing on captured camera photo. I have been looking into this for the last few days.
I know my answer is about 3 years late, but anyways: You were using double quotes in your HTML, which would not work in a JSON, since it is recognised as end of string. If you want to do anything like this in future use single quotes in HTML, so they don't interfere with the JSON.
Hi together,
here is my Solution with SVG to Merge Images without Flow/Third parts or Code-Components.
— It's a Component with Pen Input and Background

Hi there,
I tried your component, it seems to only contain the edit bit though - missing the "Change Background" and "Merge Output Image" parts your Github screenshots show - am I doing something wrong?
Hi @ShannonC ,
I will Update the Readme.
You can usw the zip File to import as Canvas App. Then you can Show my properties.
did you find the problem? I have the same one and I can't fix it
I have updated my Merge Module.

The Reading Dynamics 365 and Power Platform User Group is a community-driven initiative that started in September 2022. It has quickly earned recognition for its enthusiastic leadership and resilience in the face of challenges. With a focus on promoting learning and networking among professionals in the Dynamics 365 and Power Platform ecosystem, the group has grown steadily and gained a reputation for its commitment to its members! The group, which had its inaugural event in January 2023 at the Microsoft UK Headquarters in Reading, has since organized three successful gatherings, including a recent social lunch. They maintain a regular schedule of four events per year, each attended by an average of 20-25 enthusiastic participants who enjoy engaging talks and, of course, pizza. The Reading User Group's presence is primarily spread through LinkedIn and Meetup, with the support of the wider community. This thriving community is managed by a dedicated team consisting of Fraser Dear, Tim Leung, and Andrew Bibby, who serves as the main point of contact for the UK Dynamics 365 and Power Platform User Groups. Andrew Bibby, an active figure in the Dynamics 365 and Power Platform community, nominated this group due to his admiration for the Reading UK User Group's efforts. He emphasized their remarkable enthusiasm and success in running the group, noting that they navigated challenges such as finding venues with resilience and smiles on their faces. Despite being a relatively new group with 20-30 members, they have managed to achieve high attendance at their meetings. The group's journey began when Fraser Dear moved to the Reading area and realized the absence of a user group catering to professionals in the Dynamics 365 and Power Platform space. He reached out to Andrew, who provided valuable guidance and support, allowing the Reading User Group to officially join the UK Dynamics 365 and Power Platform User Groups community. One of the group's notable achievements was overcoming the challenge of finding a suitable venue. Initially, their "home" was the Microsoft UK HQ in Reading. However, due to office closures, they had to seek a new location with limited time. Fortunately, a connection with Stephanie Stacey from Microsoft led them to Reading College and its Institute of Technology. The college generously offered them event space and support, forging a mutually beneficial partnership where the group promotes the Institute and encourages its members to support the next generation of IT professionals. With the dedication of its leadership team, the Reading Dynamics 365 and Power Platform User Group is poised to continue growing and thriving! Their story exemplifies the power of community-driven initiatives and the positive impact they can have on professional development and networking in the tech industry. As they move forward with their upcoming events and collaborations with Reading College, the group is likely to remain a valuable resource for professionals in the Reading area and beyond.

Ayonija Shatakshi, a seasoned senior consultant at Improving, Ohio, is a passionate advocate for M365, SharePoint, Power Platform, and Azure, recognizing how they synergize to deliver top-notch solutions. Recently, we asked Ayonija to share her journey as a user group leader, shedding light on her motivations and the benefits she's reaped from her community involvement. Ayonija embarked on her role as a user group leader in December 2022, driven by a desire to explore how the community leveraged various Power Platform components. When she couldn't find a suitable local group, she decided to create one herself! Speaking about the impact of the community on her professional and personal growth, Ayonija says, "It's fascinating to witness how everyone navigates the world of Power Platform, dealing with license constraints and keeping up with new features. There's so much to learn from their experiences.: Her favorite aspect of being a user group leader is the opportunity to network and engage in face-to-face discussions with fellow enthusiasts, fostering deeper connections within the community. Offering advice to budding user group leaders, Ayonija emphasized the importance of communication and consistency, two pillars that sustain any successful community initiative. When asked why she encourages others to become user group leaders, Ayonija said, "Being part of a user group is one of the best ways to connect with experienced professionals in the same field and glean knowledge from them. If there isn't a local group, consider starting one; you'll soon find like-minded individuals." Her highlight from the past year as a user group leader was witnessing consistent growth within the group, a testament to the thriving community she has nurtured. Advocating for user group participation, Ayonija stated, "It's the fastest route to learning from the community, gaining insights, and staying updated on industry trends."
