Converting bitmap to jpeg or gif or png format.

[hhemant]

Hi everybody,
I am trying to develop an application for Nokia 7650, which can convert and save the bitmap image in formats like jpeg or gif or png. I am following the bitmap manipulation example 'BMPMANIP' and using the class 'CMdaImageBitmapToFileUtility' for converting and saving the file. But it uses the 'TMda24BppBmpCodec' & 'TMdaBmpClipFormat' and saves it as a bitmap file. I tried to replace these classes by 'TMdaPngCodec' & 'TMdaPngClipFormat' to save it as a png file. But it gives me error.

So can anybody explain me what the error can be and how to save the bitmap information I have, as a png or jpeg or gif file.

Thanking in anticipation.

Yes. I managed to save bitmap files to jpeg files. For this I had to use CMdaImageBitmapToFileUtility and CMdaImageFileToBitmapUtility class. I had to use NULL, NULL for codeces...

Hi hhemant,

You can save the 24bit bitmap to .jpg?

I also tried the bmpmanip sample code and change the SaveL( ) as following:

TMdaJfifClipFormat jfifFormat;
jfifFormat.iSettings.iSampleScheme = TMdaJpgSettings::EColor420;
jfifFormat.iSettings.iQualityFactor = 45;

iFileSaver->CreateL(JPEGSaveFileName, &jfifFormat, NULL, NULL);
iConvertState = EConvertStateSaving;

where JPEGSaveFileName is a .jpg filename

However, error is returned in MiuoCreateComplete(TInt aError).

Can you give me some hints for such an error?

Rgds,
Jason
