How to control quality of uploaded image

Support - Assistance technique
1

Hello DHIS2 Support Team,
I noticed that there is some loss of quality of a image after being uploaded in a data element. Can I upload any image without quality loss? Because some sofistacated images (e.g. ECG) become totally unreadable after upload. Using DHIS2 version 2.34.0.

Thanks in advance.

Hi @riaz.somc
DHIS2 uploads image in four different sizes. Large(1024, 1024), Medium(512, 512 ), small(256, 256) and Original. This size/dimension can be provided while accessing image resouce. For example
fileResource/<uid>?dimension=Large.

Thank you @zubair for your kind help. Now I am facing the problem when the image is uploaded using DHIS2 Capture android app. When uploaded from web browser the quality remains good. @Hannan vai, drawing your kind attention.

Hi @riaz.somc,

DHIS2 Android capture app uses MEDIUM quality to download and upload images to server. Currently, it is not possible to select LARGE quality: the reason for that was to avoid high mobile data consumption and data storage. But it is true that it could be used in certain environments (stable WIFI, etc). Please could you create a ticket in JIRA with this request?

Has anyone found a solution to this?

Changing the file format from image to file works. The picture quality remains good. I’m not sure about the storage issues though

Hi please. So where is the documentation for this? Even changing the upload quality for webversion?

Hi @lillian1n2,

webversion doesn’t impose a restriction in data quality. Would you like to change the quality of the images captured in the web app?
